Installation Notes:
The following sensors are included: TPS - IAC - MAP - CTS - MAT - Wideband O2 ECU is certified to ISO 8846, SAE J1171 & United States Coast Guard Requirements for Ignition Protection & Fire Resistance. 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 I/Os than are available. If more I/Os are required, users should choose the Dominator VMS. These kits require the use of a small diameter distributor, such as a small cap GM HEI or most MSD distributors. A large cap GM HEI will not fit with these kits. Software and firmware updates can be downloaded here for free.
