well, the same ECM was used for both MAP and MAF at times, the 7727/7730 being a good and common example. since the ECM certainly didn't change between them, would need to get ahold of one of the MAF and MAP MEMCALs and compare the LHM chips to see if they changed.

between map and maf v8 the netress was the same part number.

and that was even with changing from the 7165 to 7730/7727...

All the 730 and 727 v8 use 16072665 and 16133420 I have just noticed this on some 89 165 v8's. The other 86-89 165 v8 ones are numbered 16055375 and the 16055376.

Still looking for the post / info this is a followup to. Threads used to drift a bit over there...
Another attachment from an old ecm info page.

87? so a GM prototype?

Yes. It was supposed to be destroyed but instead got used as a racecar for a few years then ended up being restored by a Vette guy.
Actually, while searching for a proper link, I found it's an 88 MY produced in early 87 and the ZR1 RPO hadn't been assigned to the car at the time.

The car the memcal is from is the blue one near the bottom of the page.
