Which ECU for the Honda NSX NA1 1991-2005 (C30A)?

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

Most complete

MoTeC M190 13190

Can carry 60 of 61 stock functions, with 27 spare outputs and 21 spare inputs left.

Smallest that keeps every engine function

Link G4X XtremeX 109-4000

67 ECU pins. Gives up 3 non-engine functions: dash & gauges, emissions, power.

“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.
