Holley EFI Terminator X Max Engine Control Module - 3.5 in Touchscreen - GM LS-Series

Take control of your LS engine and 6L80 transmission with our Terminator X Max bundle kits! Best of all, you can save up to $90 by purchasing our kits versus the separate components. Part numbers 550-917-6, 550-918-6 and 550-928-6 add GM 6L80 and 6L90 control to the ever growing lineup of high performance Terminator X Products. Terminator X Max comes fully loaded with engine tunes for common LS engine combinations to get you out of the garage and on the road/track fast. The 3.5-inch touch screen LCD handheld contains an easy to use calibration wizard as well as tuning and gauge display functions. Also included is Holley EFI's industry-leading, easy to use software suite that allows full laptop access for advanced users. Whether you are building a budget beater or a boosted race car, Terminator X MAX has the features and technology you need at a price that won't break the bank! Additional features include real-time fuel learn, high impedance injector drivers, an integrated 1 BAR MAP sensor, and 4 programmable inputs and outputs. The inputs and outputs are ideal for electric fans, boost control solenoids, progressive nitrous control, and much more. A departure from traditional Holley EFI transmission control, the Terminator X Max ECU allows the ability to use 2007+ GM 6L80E and 6L90E transmissions by communicating via CAN with the internal TCM (Transmission Control Module). The supplied Holley EFI OBDII Transmission Tuning Handheld is used to adjust Shift Points, Tire Size and Gear Ratio. The Terminator X V3 Software provides the ability to dial in Torque Management to optimize the desired shifting characteristics when using a 6L80/90E Transmission. Terminator X V3 software also allows a user to control the Secondary Shift Mode within the Transmission TCM and allows use of Tap Up/Down Shifting.

Top racers are making the switch to Holley EFI every day. Racers like Tom Bailey who set three new records and took the overall event win on the 2013 Hot Rod Magazine Drag Week and John Scali who used it to win the 2013 JEGS All-Star race. But that’s not all. The world’s best hot rod builders and tuners are making the switch to Holley EFI. Builders like Dave Lane who used Holley EFI to power the 2013 Goodguys Hot Rod of the Year and tuners like Steve Morris who use it to build some of the baddest forced induction beasts on the planet. It’s the easiest, most refined, feature-rich system that money can buy. But, don’t take our word for it, see what the best are saying about Holley EFI!
