Computing Power
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.
Transmission Control
While manual transmission compatibility comes with each of the Jackpot 2 LS systems, select versions also include trans control for the following GM 4-speed transmissions:
- 4L60E ('96-'03)
- 4L65E ('96-'03)
- 4L67E ('96-'03)
- 4L80E ('94-'03)
ETB Control
Whether you need drive-by-cable, drive-by-wire, or both in one, the Jackpot LS EFI system has you covered.
See the compatibility list here.
** Select systems include sub-harnesses for both 6 and 8-pin pedals.
Additional Control Items
Peace of mind is priceless. Well, it's cheaper than a destroyed engine at least. With Knock Control on the Jackpot 2, you can rest assured that you have a last line of defense against dangerous knock. Never again worry about a bad batch of fuel or imperfections in your tune killing your ride without warning– Aces has your back.
For those looking for optimal launches, whether at the track or the red light, the Jackpot 2 comes with both fuel-cut and spark-cut 2-step rev limiters. These are fully selectable and configurable in the handheld or PC software.
Double fan control = double the cooling power. The Jackpot ECU can easily handle a dual radiator fan setup to keep your engine frosty.
24x & 58x Reluctor Wheel
Whether your LS engine is 24x or 58x, the Jackpot 2 gets the job done. It comes packaged with wiring harnesses for both variations, and can be easily configured for compatibillity with either reluctor wheel type.
Pre-terminated EV1/EV6
Whether your LS engine has EV1 or EV6 connectors, Aces has you covered. Our wiring harnesses come pre-terminated with the connectors of your choice, so you don't have to worry about any fiddly splicing.
2 WBO2 Sensors
The Jackpot LS system utilizes two WBO2 sensors to read each bank of your V8 engine. Dual wide-band sensors allow precise calibration of each cylinder bank, optimizing performance and allowing more thorough tuning of your engine without any compromises.
Fuel Level
Worried about losing your fuel gauge to an aftermarket EFI setup? Don't be. With your Aces Handheld Controller or app, you'll be able to see your fuel level at all times.
Master Kit Feature
(Fuel) Pump Up the Jam
Each Master Kit will come with a fuel system of your choosing. You can scroll down to read more about the available options below.
255 In-line Fuel System

Most common questions
Quick answers to our most common queries for this product.
The Jackpot 2 Super Kit 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 Super Kit are compatible with both blow-through, draw-through, and nitrous applications and are also compatible with E85 Fuels. The Jackpot 2 Super Kit' 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.

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!

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.
