HalTech Rebel LS Gen 3 and 4 ECU Kits

Haltech's Rebel LS ECU kits provide the most cost-effective, easy-to-install, start-up and drive aftermarket ECU experience. Designed for Gen 3 or 4 LS engines, the all-in-one kit concept simplifies your purchase decision, eliminating the need for costly additional accessory purchases. Each kit arrives with a Rebel ECU, main engine harness and adapter harnesses for throttle, injectors, T56 tranmission, (DBW -Gen 4) or (cable throttle and IAC – Gen 3) alternator, knock sensor, existing GM MAP, oil pressure sensors, along with a Bosch O2 and air temp sensor with weld bungs. Installation is a breeze, using a labeled and pre-terminated drop-in harness, which easily connects to existing factory LS sensors. Engine start-up is made easy through the Setup Wizard in the Haltech NSP software and the soon-to-be-released Haltech Connect app. Answer six questions – LS Engine type, cam, throttle body, MAP, injectors and coils with the Wizard prompting a throttle calibration and system check, ensuring an engine that will quickly start, idle and drive. Drivability is continually improved with Haltech's advanced self-learning while additional tuning for your N/A, turbocharged, supercharged or nitrous LS is achieved through Haltech's NSP software. Finally, the Rebel LS ECU kit is compatible with Haltech's plug-and-play CAN accessories, such as the iC-7 dash, keypads, PDM, EGT, wideband and flex-fuel sensors. Show Less
