Jackpot 2 LS EFI – TBI System
Modern EFI control for carb-style LS swaps.
Jackpot 2 LS TBI is designed for builders who want the simplicity and look of a 4-barrel throttle body setup, but with real standalone LS control behind it. Whether you’re swapping a 5.3 into a classic truck, cleaning up a street car build, or building a weekend warrior that needs consistent drivability and repeatable tuning, this system keeps the install straightforward while giving you the control that matters. The throttle body features four 100 lb/hr EV6 injectors and supports GM LS engines up to 650 HP. It’s controlled by a remote-mounted Jackpot ECU that manages fuel and LS coils, and it can be configured with built-in GM transmission control (select versions), eliminating extra boxes, complex wiring, and add-on TPS sensors.
Gen 2 Platform Advantages
Jackpot 2 LS TBI is built on Aces’ OEM-standard 32-bit ECU architecture, designed to manage input and output signals, voltage stability, and RPM response faster and more consistently than many common aftermarket alternatives. The remote-mounted ECU design also helps protect the electronics from heat and vibration, improving long-term reliability and serviceability compared to throttle-body-integrated ECU designs. Jackpot 2 also adds a more refined guided setup and learning experience, so you can get running quickly on common combinations, then step into deeper manual control whenever your build demands it.
What It Is
Jackpot 2 LS TBI is a complete LS engine management package centered around a remote-mounted ECU and a 4-bbl throttle body injection unit. The ECU controls the critical pieces of an LS swap in one system:
- Fuel control through the included TBI throttle body and injectors
- Ignition control for LS coil-per-plug (no external timing box required for basic spark management)
- Optional ECU-based GM automatic transmission control on supported applications (select versions)
It’s designed to get you running quickly using a startup wizard and base calibrations for common LS combinations, then refine drivability using wideband closed-loop learning. Self-learning is strongest on stock-to-mild builds. For aggressive cams, power adders, and anything that needs tighter control, Aces’ free laptop tuning software provides full manual tuning access.
What It Fits
Jackpot 2 LS TBI is designed for GM Gen III and Gen IV LS-based engines using the following trigger patterns:
- 24x/1x crank and cam trigger pattern
- 58x/4x crank and cam trigger pattern
The same kit works for both early 24x engines and 58x engines without needing additional harnesses, so you can buy confidently without getting trapped in a “wrong harness” situation.
Important Fitment Exclusions
This system is intended for LS swap-style standalone control and is not designed to manage active VVT or AFM/DOD strategies as part of its ECU control approach. If your engine uses those functions, plan your build accordingly (common delete/lockout paths apply in many swap scenarios).

What You Need for Most LS Swaps
Fuel System Requirements
Your fuel system must be designed to support a proper EFI regulator strategy and stable pressure under load, sized to match your horsepower goal. This matters even more on swaps where tank design, pickup location, plumbing size, and return strategy vary wildly. If you plan to run ethanol blends, build the fuel system accordingly and plan on tuning for the fuel. Note: The system does not support flex fuel sensing.
Exhaust Weld-in Bung Installation (for O2 sensor)
Wideband learning depends on proper sensor placement. You’ll need a correctly installed bung and a leak-free exhaust near the sensor to ensure accurate readings and stable learning behavior. Poor placement and exhaust leaks are some of the fastest ways to create chasing-your-tail drivability issues.
Electrical and Grounding
As with any standalone ECU, clean power and solid grounds are essential. Many sensor and drivability issues come down to grounding quality, voltage drop, or electrical noise. The system includes a PDM (Power Distribution Module) to help keep your power distribution clean and consistent, and to support swap-friendly outputs like fuel pump control and fan outputs, depending on your configuration. The PDM uses IGBT transistor control in place of traditional relay styles, which helps filter transient voltage spikes and better protect electronics connected to the system.
If You’re Running Boost or Nitrous
Jackpot 2 LS TBI is boost compatible and includes nitrous timing control features when configured correctly with the right sensors and tuning strategy. Each TBI unit includes a built-in 3-bar MAP sensor that supports up to 27 psi of boost capability when the fuel system and calibration are built to match the combination. For boost control itself, use a standalone boost controller as needed based on your setup and goals.
What It Supports (Aftermarket and Stock Compatibility)
Jackpot 2 LS TBI is designed to work with common OEM and aftermarket LS swap components as long as the combination fits the supported trigger patterns and does not require active VVT or AFM/DOD control. It is built for real-world swaps where chassis wiring, accessory routing, and sensor layouts vary, and it’s designed to keep requirements clear so you can plan the build without surprises.
Key Features at a Glance
- 32-bit Power Architecture-based processor for faster response
- Compatible with both 24x and 58x engines, with no additional harnesses to buy
- Single Bosch LSU 4.9 wideband O2 sensor
- Self-learning adaptive idle, fuel, and ignition controls
- Boost compatible
- Nitrous timing control
- Sequential fuel and spark control with individual cylinder trim
- Programmable RPM limiters and launch controls
- Multi-fuel capable (tuning-based, no flex-fuel sensing)
- Map switching
- Optional ECU-based transmission control on supported GM 4-speed automatics (select systems)
Engineered Hardware and Electrical Protection
Jackpot 2 LS TBI is built around a remote-mounted ECU architecture for durability and serviceability. Keeping the ECU away from throttle body heat and engine vibration helps improve long-term reliability. The system is designed with stable power handling and OEM-style electrical protection so the ECU and connected components remain consistent across changing voltage and load conditions that are common in swaps.
Fuel and Spark Control
Jackpot 2 LS TBI delivers modern ECU strategy on a carb-style intake setup. It supports sequential spark control for LS coil-per-plug and advanced fueling strategies through the included 4-injector throttle body, while using wideband feedback to refine drivability in closed loop once the engine is at operating temperature. It also includes the control features that matter for real builds, including map switching, ignition trim control, rev limiting, and launch control functionality.
Ignition Compatibility
This system is designed to control LS coils directly, so you get real ECU-driven spark control instead of relying on external ignition boxes for basic timing management. That’s a major advantage over generic “carb-style EFI” approaches on LS swaps because it keeps fueling and ignition strategy unified inside one ECU.
Injector Compatibility
The throttle body comes configured with four integrated 100 lb/hr EV6 injectors. Injector selection is not a decision point on this system like it is on multiport setups, because the injector package is built into the TBI unit and designed around the system’s intended power range (up to 650 HP, fuel system and calibration dependent).
Cooling Fan Control and Outputs
The system is designed for swap-friendly integration and supports common ECU-driven outputs used in LS swaps. Depending on how you configure the install, this can include typical control outputs for items like fuel pump and fans, helping keep the wiring clean and centralized.
Dash and Gauge Integration
Jackpot 2 LS TBI is designed to support common swap gauge strategies and Aces integration accessories, with handheld monitoring and optional app connectivity depending on configuration.
Fuel Level Input (Gen 2)
Gen 2 adds a dedicated fuel level input so you can bring your tank sender signal into the ECU and view fuel level directly on the handheld display or through the Aces Connect App when using the Bluetooth module. This is especially helpful on swaps where the factory ECU is removed, and the original cluster fuel signal is no longer being driven the same way.
Setup is handled through the handheld/app settings: connect the sender signal, select the appropriate configuration method, then calibrate and verify the reading (including optional smoothing/filtering if needed for stable real-world display). Once configured, you can monitor fuel level alongside key ECU data like RPM, speed, voltage, and sensor readings.
For factory gauges, most tachometers can be driven by the Jackpot 2 using a square-wave tach output. For broader gauge coverage, the included Aces handheld (or an optional Bluetooth module) can display tach, speed, battery voltage, fuel level, and other key sensor data. All Aces EFI systems are also compatible with Dakota Digital gauges using the Dakota Digital EFI BIM module.
Installation Expectations
Most installs can be completed in a little over a weekend when the fuel system plan is solid, wideband bungs are installed properly, and wiring is routed cleanly. More complex builds, such as transmission control setups, custom dash integrations, or high-power boosted combinations, will require additional time and setup.
A simple first-start checklist always helps: verify fuel supply and pressure stability, verify grounds and clean power, confirm trigger pattern selection, confirm ignition configuration, start and warm up, then allow closed-loop learning to begin.
Setup and Tuning Experience
Jackpot 2 LS is built to be approachable for first-time EFI builders without limiting experienced tuners.
Guided Setup (Handheld or Bluetooth)
After the install, initial setup is straightforward. Using the included handheld touchscreen (or the Bluetooth module if that’s the option you choose), you’ll run through the setup wizard and answer a few basic questions about your engine and configuration—things like cam type, ignition/timing setup, and other core inputs the ECU needs to start safely and learn correctly.
The wizard process is the same whether your build is stock or aggressive. Where the difference comes in is how far you rely on self-learning. Self-learning is intended for stock to mild combinations and is excellent for daily driving, cruising, and normal load transitions. Wide-open throttle pulls, dyno tuning, and higher-risk operation (especially with aggressive combinations or power adders) should be handled with manual tuning using the free laptop software.
The handheld or Bluetooth module is needed for initial setup, adjustments, and monitoring, but it does not need to remain plugged in once the system is configured and running correctly. Think of it as your setup and control interface: use it to configure, make changes, and view live sensor data whenever you want.
For stock and mild applications, the guided setup wizard and self-learning fueling strategy help deliver quick startup and strong drivability with minimal tuning complexity. Once the engine reaches operating temperature and transitions into closed loop, the system begins learning fueling in real time. After a few drive cycles, fueling accuracy and response continue to improve, and when you are satisfied with the results, you can lock the calibration.
For performance builds, the included USB cable and Aces’ free laptop tuning software give you full manual control, so you can confidently dial in aggressive cam profiles, power adders, and race-focused combinations with complete authority.
Takeaway
The Jackpot 2 LS EFI – TBI System gives you the carb-style LS look with real standalone control. You get a 4-barrel throttle body built around four 100 lb/hr injectors, a remote-mounted 32-bit ECU that controls fuel and LS coils, wideband closed-loop learning (single sensor included) for strong drivability on stock-to-mild builds, power-adder compatibility when tuned correctly, and optional built-in GM transmission control for a cleaner, simpler swap without stacking extra boxes.

What You Need for Most LS Swaps
Fuel System Requirements
Your fuel system must be designed to support a proper EFI regulator strategy and stable pressure under load, sized to match your horsepower goal. This matters even more on swaps where tank design, pickup location, plumbing size, and return strategy vary wildly. If you plan to run ethanol blends, build the fuel system accordingly and plan on tuning for the fuel. Note: The system does not support flex fuel sensing.
Exhaust Weld-in Bung Installation (for O2 sensor)
Wideband learning depends on proper sensor placement. You’ll need a correctly installed bung and a leak-free exhaust near the sensor to ensure accurate readings and stable learning behavior. Poor placement and exhaust leaks are some of the fastest ways to create chasing-your-tail drivability issues.
Electrical and Grounding
As with any standalone ECU, clean power and solid grounds are essential. Many sensor and drivability issues come down to grounding quality, voltage drop, or electrical noise. The system includes a PDM (Power Distribution Module) to help keep your power distribution clean and consistent, and to support swap-friendly outputs like fuel pump control and fan outputs, depending on your configuration. The PDM uses IGBT transistor control in place of traditional relay styles, which helps filter transient voltage spikes and better protect electronics connected to the system.
If You’re Running Boost or Nitrous
Jackpot 2 LS TBI is boost compatible and includes nitrous timing control features when configured correctly with the right sensors and tuning strategy. Each TBI unit includes a built-in 3-bar MAP sensor that supports up to 27 psi of boost capability when the fuel system and calibration are built to match the combination. For boost control itself, use a standalone boost controller as needed based on your setup and goals.
What It Supports (Aftermarket and Stock Compatibility)
Jackpot 2 LS TBI is designed to work with common OEM and aftermarket LS swap components as long as the combination fits the supported trigger patterns and does not require active VVT or AFM/DOD control. It is built for real-world swaps where chassis wiring, accessory routing, and sensor layouts vary, and it’s designed to keep requirements clear so you can plan the build without surprises.

Engineered Hardware and Electrical Protection
Jackpot 2 LS TBI is built around a remote-mounted ECU architecture for durability and serviceability. Keeping the ECU away from throttle body heat and engine vibration helps improve long-term reliability. The system is designed with stable power handling and OEM-style electrical protection so the ECU and connected components remain consistent across changing voltage and load conditions that are common in swaps.
Fuel and Spark Control
Jackpot 2 LS TBI delivers modern ECU strategy on a carb-style intake setup. It supports sequential spark control for LS coil-per-plug and advanced fueling strategies through the included 4-injector throttle body, while using wideband feedback to refine drivability in closed loop once the engine is at operating temperature. It also includes the control features that matter for real builds, including map switching, ignition trim control, rev limiting, and launch control functionality.
Ignition Compatibility
This system is designed to control LS coils directly, so you get real ECU-driven spark control instead of relying on external ignition boxes for basic timing management. That’s a major advantage over generic “carb-style EFI” approaches on LS swaps because it keeps fueling and ignition strategy unified inside one ECU.
Injector Compatibility
The throttle body comes configured with four integrated 100 lb/hr EV6 injectors. Injector selection is not a decision point on this system like it is on multiport setups, because the injector package is built into the TBI unit and designed around the system’s intended power range (up to 650 HP, fuel system and calibration dependent).
Cooling Fan Control and Outputs
The system is designed for swap-friendly integration and supports common ECU-driven outputs used in LS swaps. Depending on how you configure the install, this can include typical control outputs for items like fuel pump and fans, helping keep the wiring clean and centralized.
Dash and Gauge Integration
Jackpot 2 LS TBI is designed to support common swap gauge strategies and Aces integration accessories, with handheld monitoring and optional app connectivity depending on configuration.
Fuel Level Input (Gen 2)
Gen 2 adds a dedicated fuel level input so you can bring your tank sender signal into the ECU and view fuel level directly on the handheld display or through the Aces Connect App when using the Bluetooth module. This is especially helpful on swaps where the factory ECU is removed, and the original cluster fuel signal is no longer being driven the same way.
Setup is handled through the handheld/app settings: connect the sender signal, select the appropriate configuration method, then calibrate and verify the reading (including optional smoothing/filtering if needed for stable real-world display). Once configured, you can monitor fuel level alongside key ECU data like RPM, speed, voltage, and sensor readings.
For factory gauges, most tachometers can be driven by the Jackpot 2 using a square-wave tach output. For broader gauge coverage, the included Aces handheld (or an optional Bluetooth module) can display tach, speed, battery voltage, fuel level, and other key sensor data. All Aces EFI systems are also compatible with Dakota Digital gauges using the Dakota Digital EFI BIM module.
Installation Expectations
Most installs can be completed in a little over a weekend when the fuel system plan is solid, wideband bungs are installed properly, and wiring is routed cleanly. More complex builds, such as transmission control setups, custom dash integrations, or high-power boosted combinations, will require additional time and setup.
A simple first-start checklist always helps: verify fuel supply and pressure stability, verify grounds and clean power, confirm trigger pattern selection, confirm ignition configuration, start and warm up, then allow closed-loop learning to begin.
Setup and Tuning Experience
Jackpot 2 LS is built to be approachable for first-time EFI builders without limiting experienced tuners.
Guided Setup (Handheld or Bluetooth)
After the install, initial setup is straightforward. Using the included handheld touchscreen (or the Bluetooth module if that’s the option you choose), you’ll run through the setup wizard and answer a few basic questions about your engine and configuration—things like cam type, ignition/timing setup, and other core inputs the ECU needs to start safely and learn correctly.
The wizard process is the same whether your build is stock or aggressive. Where the difference comes in is how far you rely on self-learning. Self-learning is intended for stock to mild combinations and is excellent for daily driving, cruising, and normal load transitions. Wide-open throttle pulls, dyno tuning, and higher-risk operation (especially with aggressive combinations or power adders) should be handled with manual tuning using the free laptop software.
The handheld or Bluetooth module is needed for initial setup, adjustments, and monitoring, but it does not need to remain plugged in once the system is configured and running correctly. Think of it as your setup and control interface: use it to configure, make changes, and view live sensor data whenever you want.
For stock and mild applications, the guided setup wizard and self-learning fueling strategy help deliver quick startup and strong drivability with minimal tuning complexity. Once the engine reaches operating temperature and transitions into closed loop, the system begins learning fueling in real time. After a few drive cycles, fueling accuracy and response continue to improve, and when you are satisfied with the results, you can lock the calibration.
For performance builds, the included USB cable and Aces’ free laptop tuning software give you full manual control, so you can confidently dial in aggressive cam profiles, power adders, and race-focused combinations with complete authority.
Takeaway
The Jackpot 2 LS EFI – TBI System gives you the carb-style LS look with real standalone control. You get a 4-barrel throttle body built around four 100 lb/hr injectors, a remote-mounted 32-bit ECU that controls fuel and LS coils, wideband closed-loop learning (single sensor included) for strong drivability on stock-to-mild builds, power-adder compatibility when tuned correctly, and optional built-in GM transmission control for a cleaner, simpler swap without stacking extra boxes.

Self Learning & Fully Tunable
Not a tuning wiz? We provide the wizard, so you don't have to be. With Jackpot 2's self-learning* functionality, just answer a few basic questions in the startup wizard, and then the ECU takes care of the rest. After about 30-60 minutes of idling and drive time, the system will build its own tune so you don't have to.
For advanced users and boost control setup, you can use our free tuning software to access even more customizable settings.
*Self-learning works best for stock-mild applications. For more aggressive applications and even some stock-mild applications, manual tuning is recommended.
Boost Control
Looking to boost your ride? While all of our other second-generation EFI systems support single solenoid control, the Jackpot 2 goes above and beyond with dual Mac 3-port solenoid control*. Never worry about dangerous overboost again–our safety features will detect it and drop pressure automatically. Our self-learning features will even pull timing as it sees boost, for smooth, safe acceleration. Of course, you can always use our advanced tuning software to take it to the next level if you have the chops.
*Boost Control is currently disabled in the firmware, but will be added via a free firmware update in the summer of 2026.

Most common questions
Quick answers to our most common queries for this product.
The Jackpot 2 LS EFI - TBI System are designed to work with most stock or aftermarket ignition components. They will work with most tachometers and are compatible with Dakota Digital dashes using their Aces BIM Module (BIM-EFI-1).
Self-tuning is a common term used among aftermarket EFI companies, but we prefer the term "self-learning" as that is more accurate, even for our competitors who advertise "self-tuning."
Our systems are designed to self-learn the fuel MAPs and work best for stock-mild builds. Some mild builds and anything beyond that would require manual tuning, of which the system is fully capable. Additional features like nitrous and boost are also considered beyond stock and require manual adjustments to enable and configure these kinds of features.
Yes! You can make many changes using the Bluetooth or handheld interface, and we also offer a free PC app for more advanced tuning.
Yes to both! The Jackpot 2 LS EFI - TBI System are compatible with both blow-through, draw-through, and nitrous applications and are also compatible with E85 Fuels. The Jackpot 2 LS EFI - TBI System' MAP sensor can be scaled for up to 26 lbs of boost and can be set to retard timing.
Note that for boost, the system is compatible, but cannot control the boost. You will need to use a separate controller for things such as wastegate control or solenoid activation. Use of these features will require manual tuning.

After sitting on the phone over an hour James got my situation resolved and had great customer service and patience to get my order correct
It’s not installed yet, however all the components are very super nice quality. Very excited.
Great price with the Black Friday deal and fast shipping. Everything was packaged really nice but still working on the motor so I haven’t installed anything yet.
Have had my jackpot system for a few months now. And I can definitely say this system is great for its price!! I like the easy install, with everything labeled its kinda hard to mess up i feel. Fired up first try been running on the wizard with some minor adjustment on the handheld. I will definitely buy another system when I build another LS.
Before you believe a negative comment on here ask yourself can the person leaving the review follow instructions to install this system one mistake can make it not work correctly and they jump on here with the tech support bs they aren’t going to come to your house and do it for you follow the instructions get it to start and run then tune it doesn’t tune it’s self it’s a good product I’ve had mine nearly 2 years zero issues (I ran mine for a year before I had a remote tune done it ran good you just have to mess with it to get the AFR correct)
Bought my Jackpot just over a year ago & between everyday driving to long distance from Mo. to NC with not one issue. Once a problem did arise after a yr+ time had past (absolutely my fault) I sent in my equipment as asked & got back it back working again. Very helpful across the board from the emails to phone calls to mailing!! Thanks Again
5.3 Topend kit 🤌
So far we haven't gotten this thing sorted out yet. The engine continues to run after the key is turned off.
The PDM looks like a real nice idea but, you have to cut up and modify the wiring harness to connect it. That's not a good way to start out.
love it you can tell you guys put in the time this kit rocks ,the quality is top notch ,the ease of the wiring ,the hardware, the touchscreen,,off of the part have the exact Fitment I was looking for ,,the cherry on top the price , you can tell you do it out of love so thank you!!!!.I have used fi tech ,holley , Edelbrock and your kits hold there own ........!!!! everyone look out ace is the real deal,and now I can compete in some real competitions ty ill send pics soon ps it learned my cam with ease and grate drivability ,the power omg crisp throttle , built ,5.3 cam , ace injection , super t10 4 speed , 3,42 posi 1991 gmcSonoma
One of the easy ways to do a LS swap glad I picked this system high quality looks amazing wiring is a breeze
Don’t waste your time or money working with another system. Installation was very easy and the system had my engine running how it should have with the other management systems I’ve used. Had I known the quality and ease of use of the jackpot system I wouldn’t have been wasted the time or money on anything else. Great job on these kits!
Installed a LS3 6.2 crate motor in a C3 Corvette. Looked at all the options for engine management and landed on the Aces Jackpot LS system. Aces had a compact ECU, dual O2s, DBW, and trans control needed for the build. Main harness is nicely loomed with plenty of length, quality connectors, and all wires are clearly labeled. After plugging in all the sensor, connect 4 wires - pwr, gnd, pump, acc and it’s ready to run. The setup wizard is super easy using the 7” screen. Car started up within seconds on the second crank and settled to my target idle. This system is the best value on the market for an LS swap.
First the product was readily available when competitors was not. It came quickly very nicely boxed with everything labeled. Nice cloth loom. Very descriptive manual and labels. No for the company and their supporters. I got my truck going and headed to PTTS and the guys at the aces tent were amazing in support and helping with tuning. They were not satisfied until we got some issues resolved and it purred all the way home from bowling green to southern Indiana. I can not thank Bradley Woodall enough for his help. Long story short I completely recommend this stuff!!
I have used this kit on my own protiuring car.. a 1968 camaro.. and it has proven to be reliable and easy to use
Installed Jackpot for LS on (2) swaps, 6.0 in Foxbody and 5.3 in OBS truck, both performed well, and can't beat the price - very happy with Aces EFI!
Tony in Berthoud, CO
I got this Jackpot EFI unit to replace the stock Corvette 411 computer that I put into my Datsun 280Z. The ACES computer is nice and small compared to the corvette computer. A few things that I did not like about the system. The wire harness was very long, with these big plugs for the sub harness wires. The big plugs where designed to go in the rear of the engine. I the Datsun there is no room for them in the back because of how close it was to the firewall. I cut the plugs out of the harness and spliced the wires back together.The wire loom that was over the wires was not good quality. I ended up cutting al the loom off and replacing it with better stuff. I included pictures of before and after the better quality loom. The loom was cut short, so at the ends of the wires was any where from 2 to 3 inches of tape to cover up the short loom. The plugs for the coils where not the same as the stock Corvette, so I had to get new ignition coils. Then the injector plugs are EV6 and the stock ones are EV1. They don't have a wire harness for the stock injectors, so I had to get some adapters from Ebay. Those would be nice to have included in the kit or have the option to pick what injectors and coils you are running. the oxygen sensor wires are very long also. I would recommend that the wire harness has the option to come none terminated at the ends fro the people who want the length to be custom to make it all fit and look good.The wires had very big white labels on them. It made it easy to know where they went. But after you plugged them in there was this big label there that I had to cut off. I then wrote with a sharpee on the plugs what they went to.There was another big plug that has all the loose wires on it. Again, I cut that off and then just connected the wires that I need for my setup.
Now for the good:
The instructions are very nice and easy to follow. I like that they included the wiring diagrams for this system, very helpful. The user interface on the touch screen is great. The setup was easy, I just answered a few questions and then the car started right up and ran great.I like the two wide band oxygen sensors that come in the kit. It does take a few more rotations of the engine to start than the Corvette computer. I liked the included rubber mounts for the computer. The kit came with it's own relays and two inline fuses. I got the upgraded 7 inch screen, which is nice. I mounted it to the front of my dash for now while I tune the engine, then I will remove it after that.
Overall this is a great system. I am glad I got it and I will get another one for my next project.
This Jackpot EFI system is great, Thank you.
Bought the jackpot and harness kit for my car. Easy to work with and quality parts ! 5 stars !
This is truly a great system very easy to install and the wizard is so easy to understand if I can do it anyone can great job! Aces you guys are awesome and the customer service and tech team are so helpful, if you need a system Go Aces !!!!
