Initial Bench ecm testing (Programming 101 included)

[Bruce Plecan]

Grounding the gear switch or not, vss signal or not make no huge
difference in injector pulse widths.  Using me eyes and O-Scope
can measure no differences in pulse length/freguency, but follow
up testing to follow with more accurate PWM devices.

Applying a lower than desired rpm to the ecm doesn't make the 
IAC extend fully, matter of fact it stays a fair ways out.  When close
to but higher than desired rpm it extends all but to about the last 30
counts.  

There was mention of a 747 bin that cycled the knock counts to
255, then 0 to 255, and kept repeating that, it's BCC ABUL.

Cheers
