[Shotimes] Which MAF is best?

[John Weidenbenner]

I went through the same problems on my 93 atx. After changing to the TSB
upgrade H3Z2 PCM I installed a BOS. I never found, after 8 program changes,
an LPM program compatible with the H3Z2.

Paul Thomas, on the other hand, has the original 93 atx H3Z PCM  which in
compatible with his BOS.
