Product Info

Overview

Adding a TBI system to a GM LS engine has been done for years, but the JACKPOT series GM LS TBI EFI makes the conversion easier than ever! The throttle body features 4 100 LB./HR. EV6 injectors and supports GM LS engines up to 650HP and is controlled by a remote-mounted Jackpot ECU. The ECU controls not just the fuel, but also the LS coils, and can be configured with built-in GM transmission control, eliminating the need for additional boxes, complex wiring, or add-on TPS sensors, saving you both time and money. The same kit works for both the early style 24x engines, as well as the 58x engines, without the need to buy additional harnesses. The kits with GM transmission control come with harnesses for popular 4L60E, 4L65E, 4L80E, and 4L85E transmissions. Jackpot TBI comes with base maps pre-installed for common LS combinations to help you dial in your engine and get on the road more quickly.

Jackpot GM LS TBI is also available in a Top End Kit, which adds a mid-rise single plane aluminum intake manifold with the required 4150-style mounting flange. Intakes are available for both cathedral (LS1/2/6) and small rectangular (LS3) port cylinder heads.

Features:

32-bit Power Architecture® based processor for faster response
Compatible with both 24X and 58X engines with no additional harnesses to buy

Computing Power

A robust ECU that utilizes our OEM standard 32-bit architecture. This allows the system to manage input/output signals, voltage, and RPM faster and more consistently than our competitors.

Plug 'n' Play

Not a tuning wiz? You don't need to be since we provide a wizard for you. Our self-learning* functionality means you only have to 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.

*Self-learning works best for stock-mild applications. For more aggressive applications and even some stock-mild applications, we offer free tuning software on our website.

It Takes Two

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.

Pedal to the metal...and the wire

Whether you need drive-by-cable, drive-by-wire, or both in one, the Jackpot LS EFI system has you covered.
** Select systems include sub-harnesses for both 6 and 8-pin pedals.

Aces Fuel Injection, Inc. Jackpot LS (Lite)

A need 4-speed

While manual transmission compatibility comes with each of the Jackpot LS systems, some versions also include trans control for GM 4-speed transmissions such as 4L60E & 4L80E.

Master Kit Feature

Master Kit Feature

Distributors for Days

Each Master Kit will also come with a Distributor of your choosing and an ignition coil to allow you to run timing control.

ACES Fuel Injection. Black Jack Pro Distributor

Magnetic Pickup Distributor

With over 15 options to choose from, our line of Black Jack Pro Magnetic Pickup Distributors lets you run your EFI with mechanical advance or lock it out to allow the ECU to control timing.

Ignition Coil

The high-output magnet in the Black Jack Pro Ignition Coil creates 50,000 volts, or about 70% more spark energy over most stock-style applications, giving you a significantly hotter and larger spark for more complete combustion. This helps create more horsepower and torque, providing smooth acceleration throughout the entire RPM band.

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.

Android is available via download here, or in the Google Play Store Fall of 2025.
iOS is available Fall of 2025

Most common questions

Quick answers to our most common queries for this product.

Will it work with my engine and existing components?

The Killshot Fusion is designed to work with any classic 4, 6, or 8 cylinder engine that is under 650 hp, uses a 4150 style flange, and has a fuel system rated for EFI (43 PSI).

The self learn will work for most stock-mild builds, while some mild and more advanced builds may require manual tuning.

Will it work with aftermarket components?

The Killshot Fusion is designed to work with most stock or aftermarket ignition components. It will work with most tachometers and is compatible with Dakota Digital dashes using their Aces BIM Module (BIM-01-2-ACES).

Is it self-tuning?

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.

Can it be custom-tuned?

Yes! You can make many changes using the Bluetooth or handheld interface, and we also offer a free PC app for more advanced tuning.

What do I need to upgrade from Carb to EFI?

The Killshot Fusion can work with standard stock or aftermarket ignition components, but if you want to run timing control, it will need either a magnetic pickup distributor that has been locked out or a Hall Effect distributor. You will also need to make sure that your fuel delivery system can support 43-58 PSI. Whether or not you need a return line will depend on your fuel delivery system and if the regulator is inside or outside the tank. Whether or not you need to replace your tank will depend on which fuel delivery system you choose. We offer complete Master Kits for each EFI system that come with new ignition components and a fuel delivery system. You can visit the Killshot Fusion Master Kits page here.

Is it boost & E85 compatible?

Yes to both! The Killshot Fusion is compatible with both blow-through, draw-through, and nitrous applications and is also compatible with E85 Fuels. The Killshot Fusion's 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.

Super Fast Shipping!

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)

Well when opening the box I thought this would be a great system. But once getting everything out and laid out I noticed I recieved a Jackpot 2 ecm. Not jackpot Pro LS ecm. Got everything hooked up and no start. No injection or coil pulses. Tried to email tech line no reply. Then got a hold of tech line said problem was I needed to add relays in there harness. So I did that and still not running. Tech line asks for pictures of install which makes no sense system doesn’t run. Not due to wiring routing or anything else. Still waiting for tech support to get back to me. Will update if the system does start and run or is waste of money.

purchased Jackpot EFI for LS motor June 2025. Received kit with very different inventory parts than paperwork. Worked out with customer service. Easy install but system didn't work. Tech help supplied replacement MAP. Didn't help. Next tech call indicated ECM fault, but try a couple changes. Didn't help. Called to request warranty coverage (under 90 days) and suddenly No calls returned!
Email confirmed Warranty coverage, but needed tech to return call to process. After 2 weeks of calling and emails not returned, I did a reverse charge through credit card as fraud.
Look under "aces tech help" page and see how prevalent this is. Bad product with intentionally bad service.
