Description

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.

Features:

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 wide band O2 sensor
Self-Learning adaptive idle, fuel, and ignition controls
Boost compatible
Nitrous timing control
Sequential fuel and spark control with individual cylinder trim
Systems with GM transmission control include harnesses for most popular GM 4-speed automatic transmissions
Programmable RPM limiters and launch controls
Multi-fuel capable
Individual cylinder ignition trim (RPM based)
Map switching

The Jackpot TBI system was designed with a 4150-style flange. If your manifold is different, you can simply use a flange adaptor to make it work.

Computing Power

A robust remote-mounted 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. A remote-mounted ECU allows it to avoid dreaded heat-and-vibration-induced hardware failures that are prevalent in other aftermarket systems.

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.

Boost it, baby!

Each TBI unit comes with a built-in 3-bar MAP sensor that will allow you to run up to 27lbs of boost!

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.
