Which ECU for the Ford Mustang GT 2011–14 (Coyote 5.0)?

Every ECU below has a harness for this car. They all run the engine basics; the difference is how many of the stock ECU's other functions each one can still wire, and how much spare I/O is left for add-ons such as boost control or a wideband. “Of 59” counts the stock functions at least one ECU here wires.

Confirm before building, whichever ECU you pick:

  • Needs CAN (ford_mustang_2011_14); not documented for this ECU
  • This car has PATS immobilizer; needs a delete/bypass

The wiring below doesn't depend on these, so these harnesses are drafts until someone confirms them.

Most complete

MaxxECU PRO REV10+

Can carry 56 of 59 stock functions, with 33 spare outputs and 27 spare inputs left.

“Smallest” is by pin count, not price. Picks come from harnesses with no validation errors (none here yet, so all are considered).

Categories are read from the stock pin names and are a guide; each item shows its full stock name. Power and ground pins aren't compared, since every harness powers and grounds the ECU. Prices aren't considered. Always check the harness's own findings before building.
