    Complete 1999-04 Ford Modular Engine Plug and Play Engine Control Kit - Uses Jetronic ''Bosch Style'' injector harness & Bosch Wideband O2

    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.

  • Designed specifically for 1999-2004 Ford Modular Engines
  • Plug and play with factory sensors; crank, cam, TPS, coolant temp, etc.
  • Plug and play with factory actuators; coils, injectors, IAC
  • Connectors for Holley fuel pressure and oil pressure sensors
  • Connectors for expanded inputs and outputs
  • Complete plug and play kit includes HP ECU, Bosch wideband O2 sensor, MAP sensor, coil drivers and all necessary harnesses

  • so with the Holley Dominator being so close in price the difference is minuscule really, its huge Landry list of capabilities endless amounts of features it would seams to be the better option. Or is there any reason or benefit to this kits instead?

    With this kit you will still need to provide the throttle body. EFI is superior in most applications. There are a number of complete kits like this option http://www.jegs.com/p/FITech-Fuel-Injection/FiTech-Easy-Street-EFI-600-HP-Throttle-Body-System/5109244/10002/-1

    Can you run e85 or alcohol?

    Asked by: CUNDN Racing
    The ECU can be used with E85, but your fuel delivery system will need to be selected to run E85.

    2003 Grand Marquis. 4.6L 2v, COP. I'm building a tube frame buggy with a T45 and I want a clean wire install. Any reason why this wouldn't work for my project? Would this be a push button start kit?

    Asked by: Hinz Fab Haus
    This would work for the EFI portion of your installation. Please review the installation instructions tab on the web page for more details.

    What about transmission management? We have a 4R75E behind the 4.6 and this kit appears to only take care of the engine. Is there a kit for both, or a separate controller?

    Asked by: Biggerman
    This kit will only control engine management. Transmission control would need purchased separate.
