[s-cars] WTB : MAF

[Michael Bess]

IIRC, when I got the MRC software, there were differences if you used the
stock MAF vs. the RS-2.  In addition, the Pastore-Eichlin software
specifically requires the RS-2 MAF.  I believe the voltage-flow rate curves
of the two MAFs are different at the top end of the range, although very
similar at the low end. Thus you run the risk of non-ideal A/F ratio
(uncertain if too lean or two rich) under high air flow conditions.

Whoa, dere, Mark.  I wouldn't be assuring you it's a direct hardware  
fit.

It's beyond my personal experience, but I didn't see anything changed  
in the software for the MAF change.  You'll have to get that  
confirmation elsewhere, like a
second opinion, good practice anyway.  There have been others say  
that they have interchanged the MAF with no effect on operation.  I  
just wanted to point out
that options do exist if you are having trouble with the stock part.

Tom      Sorry I can't be more help.
