    Looking for a plug and play kit for your Ford Modular 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. 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 ECU. ECU is certified to ISO 8846, SAE J1171 & United States Coast Guard Requirements for Ignition Protection & Fire Resistance.

  • I have a couple of questions 1 of them is can this be used on a 97 f150 even tho it says it's for a 99 and up and will this also run the transmission I tell to make it work properly

    Asked by: Sparkplug110
    You will need to modify the wiring harness and add the required sensors to make it work on a 1997, it is designed for the 99 and later applications.

    Will this kit run the 2008 5.4 4 valve with fly by wire throttle pedal?

    Asked by: Justin1984
    Yes, this should work for your application. Here is a link to the instructions -http://www.jegs.com/InstallationInstructions/500/510/510-550-616.pdf
