Jackpot LS
Adam Wichers
Adam Wichers’ 1986 Toyota Corolla AE86 GTS has been heavily upgraded with modern performance parts while keeping the car’s original character. Power comes from a 5.3L aluminum LS engine with an ACES Jackpot system, paired with a T56 manual transmission. This setup delivers strong performance and a true driver-focused feel. A Fox 8.8 rear end was added to handle the increased power and improve durability. The suspension has also been fully addressed. The car runs a full T3 suspension setup along with Annex Suspension Club Sport Pro coilovers. Together, these components improve handling, stability, and overall feel.

Jackpot 2 LS
A complete standalone ECU, wiring harness, and sensor package designed to control LS-based engine swaps without relying on the factory ECU.
Fully tunable with self-learning fuel control, Jackpot 2 LS gives builders the flexibility to get running quickly and fine-tune deeper when they’re ready.












Jackpot 2 LS EFI - TBI System
3-Year Warranty
30-Day Returns
Secure Payment
The Jackpot 2 LS kits are designed to be compatible with 1997-2014 GM Gen III & Gen IV LS based engines that use either a 58x/4x or a 24x/1x crank & cam pattern. Common compatible engines include LS1, LS2, LS3, LS6, LS7, LS9, and many popular LS swap variants such as 4.8L, 5.3L, and 6.0L LS-based engines. Compatibility is determined by the trigger pattern and engine features, not just the engine nickname, so confirming the crank and cam pattern is one of the best ways to validate fitment.
Want all the advantages of EFI on your LS engine but crave that classic throttle body look? Look no further. The Jackpot 2 also comes in a Throttle Body configuration, so you can get that heavy, old-school look you love under the hood, as along with four 100 lb/hr injectors and the muscle to handle up to 650 naturally-aspirated horsepower.
Jackpot 2 LS TBI is designed for builders who want the best of both worlds: a simple, guided setup that gets you running fast, plus true standalone ECU control that scales up to advanced tuning when your build demands it. Jackpot 2 LS TBI is built to keep the install clean, the drivability strong, and the control in your hands.
For stock and mild builds, the setup wizard and self-learning fueling strategy help eliminate the intimidation factor of tuning. For serious performance builds, the free Aces laptop tuning software unlocks full manual control and calibration refinement.

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.
How do I set up and program my system?
Interface Options
Our EFI systems are self-learning for most stock-to-mild engine builds. You’ll use one of the included interface modules (depending on the option selected at purchase) to complete the initial setup and make adjustments on the fly. The startup wizard will prompt you with 6–12 setup questions, after which the self-learn feature takes over.
Additional fine-tuning may be required later, depending on your specific build.

Bluetooth Module
Compatible with Android and iOS devices and plugs into the CAN connection on the main harness.

5" Handheld (3rd Gen)
- Capacitive touch screen
- 64-bit processor

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.

Donavan McDaniel
So, Donavan McDaniel reached out to us this week and showed off his 84 Chevy S10 Durango, and can we just say it looks AWESOME! The truck is a standard cab long bed. He claims it to be a survivor as it came from Ohio with very little rust. Donavan has since addressed the rust, and is putting a 5.3 and 5 speed manual in it from a Colorado. It is not running yet (although it will be running a Jackpot), but Donavan will begin addressing it when he gets back from deployment. Thank you for your service Donavan, and thank you for sending in your beautiful build!

Jakeus Olson, can you or can you not jump a coke can in the K-Mart parking lot?! Thank you for sending us these pictures and videos of your LSA S10! That motor sounds like an absolute beast! All of us here at Aces are tipping our hat to you today. For those that want to know he's running a Jackpot with a Dakota Digital Dash.
