Which ECU for the Chevrolet Corvette C6 2005-13 (LS2/LS3/LS7)?

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 89” counts the stock functions at least one ECU here wires.

Confirm before building, whichever ECU you pick:

  • Needs CAN (GM E38 (C6 Corvette)); not documented for this ECU

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

Most complete

MoTeC M190 13190

Can carry 88 of 89 stock functions, with 13 spare outputs and 20 spare inputs left.

Smallest that keeps every engine function

MoTeC M150 13150

120 ECU pins. Gives up 4 non-engine functions: charging, dash & gauges, emissions.

“Smallest” is by pin count, not price. Picks come from harnesses with no validation errors.

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.
