Flash! '747 supports MAF

[Ludis Langens]

Someone who poked around the 1227747 circuit board e-mailed me the
results.  The '747 has a complete MAF input circuit!  Hardwarewise, all
you need to do is connect a GM MAF to pin B6 of the harness.  Software
is the only missing part.

[gotta change my sig]

               unsigned long BinToBCD(unsigned long i) {unsigned long t;
Ludis Langens     return i ? (t = BinToBCD(i >> 1), (t << 1) + (i & 1) + 
ludis at cruzers.com            (t + 858993459 >> 2 & 572662306) * 3) : 0;}
