ECU & Harness

Complete 1997-Up GM LS Engine Plug and Play Engine Controller Kit

Looking for a plug and play kit for your GM LS engine? The HP ECU allows you to accurately control the fuel and ignition of your engine plus much more! Is your cam too wild for a MAF? Power adders? You name it, and Holley EFI can handle it. Kits are not designed to control VVT (Variable Valve Timing) or Drive-by-Wire. VVT should be locked. Dominator ECU is required for drive-by-wire applications. Holley HP EFI systems are equipped with 4 programmable inputs and 4 programmable outputs that are ideal for most vehicles with a single power adder. This feature allows the user to configure the system to support a wide range of controls including boost control, progressive nitrous, water/meth injection, speed inputs, fuel pump control, AC inputs, timing retard inputs and various other uses. When selecting an ECU, users need to ensure their planned controls can be run with the 4 inputs and 4 outputs as certain combinations may use more inputs/outputs than are available. If more inputs/outputs are required, users should choose the Dominator VMS. ECU is certified to ISO 8846, SAE J1171 & United States Coast Guard Requirements for Ignition Protection & Fire Resistance.
