I have a MN12 EEC tuner that I am selling. It is a v5.2 and I was using it in a 90 xr7/sc with A9U2 computer code. Will this tuner work with other SC computer codes, or is the unit I have specific only to the A9U2 EEC? Just wondering what SC's it is compatible with for potential buyers.

I've used mine in both in the 89 and 94. I believe the 92-93 M2y had problems.

I believe Bill McNeil is running the same EEC tuner in his '93 SC with M2Y EEC. I don't think he's had any problems with the tuner whatsoever. I was pretty sure that all ShiftMaster EEC Tuners V5.1 or V5.2 would work with any year of SC, and any EEC for the SC's.

Perhaps Dr. Fred or Brian Herron or someone like that might know differently.

Best regards,

Sean

Anything newer than V5.1 wouldn't work in my 95.
