Changed VIN how did I lose my Credits
New user got the HP Tuners today and changed the VIN as directed by Steve Williams (Tuned By Frost) and somehow I've lost the two credits I just purchased. When I try to flash a file I get "vehicle unlicensed". When I did the VIN change the popup message said something like all the parameters matched for the VIN change. I sent the ECM to Steve for a tune last month, received the ECM back, installed with the new LQ9 build. The truck has a horrible mid throttle stumble so I decided to purchase HP Tuners to get some help with the tune. Now I'm further from getting this tune resolved, out $600 for the MPVI Pro and two credits not counting the $200+ sent to Steve
I did open a support ticket number 137081

"At some point you will likely want this gone over in person. After I tuned it, I used a tool to force the VIN to your V6 VIN that matches the truck. This will be a problem for many tuners in the future. Print or forward this email to them and it will explain and tell them how to be able to work with this. Normally, if a controller like yours is setup for a 5.3/6.0/whatever, it CANNOT contain a V6 VIN since there is no V8 matching software for this VIN, only V6. You cannot flash the controller with a file from a V8 that has a V6 VIN in it, but what *I* can do is to to flash it with the V8 VIn and tune it, and THEN use a different tool to change the VIN after the fact. That let's me match it up to your truck.
So what's gonna happen is when your buddy/local shop with HPTuner's READ your ECM to start in-person tuning, it's going to give them an error after they read that will say" WARNING: VIN/OS Pair Mismatch detected, re-flashing will be disabled for this file". That means what it sounds like... they read it out, but they can't change it at all (even on their laptop, much less to actually flash) because of the VIN we are using. Once the file is read out, you will open the VIN tool in HPTuner's and CHANGE THE VIN ON THE FILE to 1GCEK19TXYE272282 and then SAVE the file. That VIN matches the actual software now being used on your truck for this motor/trans combo.
Once they change this, they will be able to re-flash and tune-away on your file. If they do not have the secondary tools to put it BACK to that matching V6 VIN when it's done, and you want it done, we will do it for you/them for this instance for NO CHARGE other than shipping and handling back and forth. So you can take it somewhere and have it dyno/street (whatever, just use a wideband) tuned, and if they can't get the VIN back, you flip it back to us and I'll fix that and get it right back out. If your tuner uses many different tools, they will be able to work around this, but HPTuner's (the popular tuning choice) will not allow the mixed VIN."
