Anyone well versed in HP tuners?

I have some questions about credits and VIN's.

I pulled a tune off a car before it went to dealer. I have no idea what the dealer did, they may have flashed it back to stock.

I hooked the tuner back up to the car when I got it back from dealer and it wanted me to re-register the car and use 2 more credits. I agreed to that and now it still won't write the file without using another credit.

Any idea what's going on?

HP tuner pro on GM car.
 
No, only if they changed the Traceability Number and Broadcast Code (which should only change if either 1. I do it LOL or 2. They replace the ECM).

I'd be curious to see the vehicle data portion (where it shows the segment ID's) of the old file and the new read.

OK, now you went WAY over my head...:lol: I have the file I pulled off the car before it went in. I will try to pull the file off the car now.
 
All of my tuning shit is packed up sadly :( Basically all I wanted to see was the vehicle info screen that should have the vin and segment ID's for both reads I believe that shows the traceability or some other identifier.

When I hooked it up, it only gives me the option to write to the vehicle, the read icon is grey. Does that mean that its the same file that I currently have on the computer?
 
If I were to read it right, and you did the following:

A] Applied credits to the PCM for that vin.
B] Read the PCM for that vin
C] Saved the PCM file from aforementioned "Read" for that vin.
D] Flashed the PCM with inputted parameters meeting the vehicles needs for that vin.
E] Flashed the PCM back to stock using the previously saved "Read" flash file for that vin.
F] Took the vehicle to a shop that applied there own "flash" or "update" to it not using the same file nor software you have been using for that vin.

That raises great probability that the credits first used are now o.b.e. and will require new credits to get your pcm back to the file it once had.
If you extract another PCM's flash file and want to load it over (in to) your PCM, chances are you will need to also apply credits (license) to enable the use of that function as well.

2 for the first time
2 from the dealer override
2 for the use of the second vehicle file
=
6 credits in total if I am assuming the for three attempts.

I read the file, saved a copy of it. Did not write or change any parameters.

Took the car to dealer. No idea what they did. They may have flashed it, not sure.

Hooked up the tuner after picking up from dealer and tried to write the unchanged file copied before the dealer.
