Use Vin Number to get an OS??

[auspeed]

I have found a service that allows me to convert an holden Vin number & it provides the calibration the car should have..

Is there anyway to work out what OS a car has if I know the calibration #?


I'm not aware of a register that shows what calibration relates to what OS.


I'm trying to have tunes pre-built before the car arrives...

Is it like this: http://tis2web.service.gm.com/tis2web

when you enter the VIN it tells you the id's of all the calibrations including the OS id.

yep that's the one... e38's give OS but LS1B's dont appear to.. they give a cal id

You wont be able to have tunes pre-built for incoming cars unless you use Tis2Web and flash a new PCM/ECM and use that. This just tells you the latest OS for that make/model/year, it has no idea what's actually IN the car now.

Do you see something like this:

14721 14722

well i was thinking I could use a pre-built file and use the compare & update function or make a script to update the OS in the car...

Just looking for some time saving....
