This ECU was originally for GTO use outside the US in the Z16A frame with engine 6G72. It is for non turbo models with both 4WD and 4WS.

It was used for both MRPM 4 speed auto and MNPN 5 speed manual models manufactured from Oct 1992 through July 1994.

It is available from a Japanese parts store (Amayama) for just under USD1000.

I do not know its compatibility outside the models it was originally manufactured for. That’s for minds smarter than mine to figure out. :)

This ECU (MD189410) was preceded by part MD159961 in earlier years and superseded by part MD310343 and MD310342 in later years all also for non turbo 4WD/4WS Z16A frame.


If there’s someone out there that needs this in the US or elsewhere, let me know. It’s for sale, and I’m willing to ship overseas to any interested buyer.


Before buying, be sure to verify that this part number is what you need for your vehicle.
