[Gmecm] Fuel Trim

[Darren Freed]

The '95 monte 3.4 was still OBDI, at least with the '6401 pcm.  The
things you're looking for in the aldl list are integrator (short term
fuel trim) and BLM (long term fuel trim).

Interesting responses... Did you get what you were looking for??
The scaling details convert the raw integrator(short term fuel trim)
and 
block learn (long term fuel trim) numbers into +/-1-100%
Try these in Mode $01
