Aces Jackpot LS EFI - 4BBL TBI System

The JACKPOT series GM LS TBI EFI system converts GM LS engines, supporting up to 650HP, and is controlled by a remote Jackpot ECU that manages fuel, coils, and transmission control.

• 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.
• The same kit works for both the early style 24X engines, as well as the 58X engines, without the need to buy additional harnesses.
