The Best of Breed in EEC Performance Tuning

We support more than 5000 processors covering 1984 thru 2004. Please select one or more categories to determine whether support for your specific application exists. If there are no search results found, you can email us at  and we can confirm for you if your application is supported, as there are many EEC-IV calibrations that have yet to be entered into our database.

You can search on the Year AND/OR Model name  OR you can search for your specific calibration code (aka catch code). This is NOT a complete list and may contain models that have the unsupported new processors that Ford switched to in 2005. There were some crossovers earlier than 2005. Many of the supported EEC-IV catch codes have not been entered, but we will add them as time permits.

See below for information on the location of the EEC/PCM in various vehicle models, the catch code (Yellow Circle) and hardware code (Black Oval) location.
