gm dealership couldnt flash pcm?
I took my car in (six speed swap) to get the pcm reflashed, but the guy told me he couldn't do it with my VIN. I know the car had an hptuners tune on it before, but would that stop it from being reflashed?
I didn't want to spend 500 bucks on something that was so simple , and was told gm could do this. Any explanations, or is my car just too old?

When I called him he said it would be "78.72" to reflash it, and he sounded pretty confident. When I took it down their to get it done he said he couldn't do it because of my VIN. He said I would probably have to pay a tuner, and I asked him why it wouldn't let him and he just said it was my VIN.

when the gm technician uses Tech 2 they are carrying a 'SPS' they plug tech 2 into the car to gather the cars info to put a tune in... the way he needs to do it is just to program it through 'Pass Thru' not 'SPS' meaning he tells it what vin to put in and it will flash it. You vin doesnt state whether it is auto or manual. only who made it where and what body shape and engine along with year.
if it is locked with HP's or EFI Live then tech2 will not be able to program it

This happens all the time. Tell them to IGNORE THE VIN.
Get a vin for a 6 speed car of the same year etc
Father is recently retired service manager and I order parts all the time. If you give them the VIN number and it didnt come with the car you are LOOKING for trouble, most likely they will send you what belongs on the vehicle...

Techs are used to doing updates with a Tech2 and nothing more.

if the tech was to just start at the PC without reading the car first then as he goes through the steps it will ask what VIN , he sticks the correct vin for your car then selects down the list whether its auto or manual and it will grab a manual tune

This should not be that hard.
When using TIS, choose "pcm replacement" and regardless of the file in the pcm, (provided it is not locked, or custom OS from hpt that acts locked) the stock file for said vin will get programmed, and the vin number will be reprogrammed.
This can be done without having to go into passthrough mode, remote is fine.
Unfortunately, 90% of dealership techs do not know anythign other than teh basic "check for updates" method of using a tech2, This is why I am glad I have access to a tech2 and tis2000.

Lets not bash GM techs here. We aren't idiots. Dealerships are not performance shops, so we don't do that kind of work. They probably don't want to be held reliable for any problems you may or may not have. We get too many dumbass people that try to blame every problem they have with some sort of repair we have done to their vehicle. If you want work like that done to your car take it to the right shop, not a dealership.

It is always funny how people on the internet are always better at diagnosing and fixing their cars than the dealer technicians. It pretty easy when you only have to worry about your one vehicle and not 20 different ones that have 20 computers each and 10 different model years.
