Default 92/92 and 94/95 MAF not the same

I recently found they are not the same. When I have my 94 MAF sensor on, I set my AFC to 105 at the lowest setting and it idles. 105 with the 92 won't idle. I had to set it to 113. 113 isn't perfect, it'* a little high, but it doesn't die. I may take it down a notch or two.

That was tried awhile back. I'll confirm for you that they are not the same. Use the each MAF in the TB of the same year.

do 94 and 95 interchange? that would mean a 94 L27 and a 95 L67.

These TB'* interchage right with a L27 gasket? (94-95)

I don't think the MAF'* are the same. The L67 pulls a TON more air through the same TB. I'll do some digging if I have time tomorrow to confirm this if nobody else pipes up.

93 MAF'* are the same regardless of engines. Checking the P/N on the MAF itself, and i'm running one in my car.

If more air goes by, the MAF'* signal reflects it.

I could try the 93 SE MAF I've got to see what happens.
