The Holley Terminator X system is an excellent standalone ECU upgrade to control your Fox Body Mustang. Most of the fine tuning can be done on your own or in a controlled environment with a dyno. However, like any new system the startup and base calibration may not be suitable for your vehicle. It may hardly run or run very poorly. There are actually a few things the owner must do in the software versus the included handheld.

Here is what you are getting with an Anderson Base Tune file for the Fox Body Terminator X ECU: Appropriate Sensors for your specific application, fresh timing map more closely related to your combination (conservative for boosted applications), a better target air/fuel map, adjusted startup settings, and correct pin map settings for Ford. This applies for both Anderson Gen1 and Gen2 kits.

*We highly recommend some basic - midlevel computer knowledge or contact a remote tuning service to assist if you are uncomfortable navigating through the software.

Please read and understand the following:

PLEASE READ YOUR TUNE FILE EMAIL IN ITS ENTIRETY!!!! This email will contain basic instructions on setting up.

There will still be a few steps that the end user MUST do before driving on the included tune. You will still need to verify your timing under static timing. You will also still need to do a TPS autoset (usually prompted when powering on the ECU and loading the tune file) You will want to confirm the IAC percentage once vehicle is warmed up and adjust the throttle blade if necessary (perform TPS autoset if you change or adjust throttle blade)

REMEMBER!!!!! This is a base tune file only and can be adjusted by the end user or tuner. We do NOT send revisions nor do we provide e-mail tuning assistance or remote tuning assistance at this time. This should be performed in person at a performance shop, dyno facility or remote tuning service.

The tune files sent are created using V2 or V3 Terminator X software. Please confirm which firmware on the ECU you are using (in the form). V2 users will need to have build 80 firmware updated in the system. - As of early 2024 Holley has been sending out ECU's that have V3 build 110 already on them. You can confirm this on the box of your ecu.
