is a link I found whilst rummaging around in the
seattleautomotive.com web site. If you go through
the drill you will get a list of GM PCM calibrations
(just numbers, not the files or anything like that).
Vehicle Calibration Information
VIN: 2G1FP32Gxxxxxxxx Summary
Selected # Description
12212156 OPERATING SYSTEM
9358576 ENGINE
9358901 ENGINE DIAGNOSTIC
12587156 CALIBRATION TO IMPROVE 2-3 UPSHIFTS UNDER HEAVY THROTTLE
16264429 TRANSMISSION DIAGNOSTIC CALIBRATION
16264619 FUEL SYSTEM CALIBRATION
9373540 SYSTEM
9362080 SPEEDOMETER CALIBRATION
Now, what interests me here is the apparent revised
transmission tune 12587156. I've tuned my own car
for the same thing (among many other details). But
I wonder whether anybody here has had this redo,
done and better yet, read it back out with HPTuners
so I could get a look at what's been modified.
