re. MAC 14

[Ben Swann]

Keith,

I assume the '90 200 is a dual knock sensor MC-2 engine car.  The MAC-14 would be the ECU that goes in that car.  There was probably a VIN break where they began using full Motronic in the non-20V engines whcih probably merged into the 100 line in the '91-92 timeframe, but I don't know about the specifics and am at best speculating.

That aside, the MAC-14 you have should work fine.

p.s. LMK if you need a chip for it.

I picked up a MAC 14 from what was allegedly a '91 200, now I wish I woulda looked closer to confirm exact model year.

However in looking at SJM's site it appears the '91 MY never rec'd a MAC 14?  If not perhaps the donor was a '90.

Question is, if I plug this into my '90 200 am I looking at any potential damage?  A MAC 14 is a MAC 14, no?

It looks like the 20V's got Mototronic ECM's, so if I've got something with Hitachi MAC 14 stickers on it it definitely didn't come from a 20V, right?

Finally, the donor was an auto and my 200 is a manual, but from what I gathered from the archives it shouldn't matter as far as ECM's, correct?
