GM Vehicle Calibration Information

[Fran and Bud]

This is probably "old news" but I just found out about it!

"Obtain the latest engine controller calibration information for your
vehicle
 simply by entering the vehicle's 17 character Vehicle Identification Number
(VIN).

 Vehicle calibration information includes any 1993 or later model year GM
 vehicle equipped with a reprogrammable engine controller (PCM or VCM).

 See 'Help' for specific calibration information vehicle coverage."
