165 to late MAF

[Craig Moates]

You can select the option to read MAF as voltage or frequency, right? I've
used the BUA for a while now on my 87 TA, which has a Bosch MAF, and it
seems OK. On the 9340 BUA, I checked bit #2 at loc H$0014 and it was already
1, same for the 1728 version. However, if you look at an APYU (89 Camaro) it
is zero, suggesting frequency. My stock ACXS (87 305 TPI TA) also has a one
in bit #2 location. I'd be interested to hear about '165 applications using
the frequency-based MAFs. Like you said, Bruce, it looks like the
architecture is there in the code.
