Attachment 141005Attachment 141004

Hello,

I need an opinion to do the right thing. I'm trying to return my stock file to my LBZ and I had got my stock file from the tuner that he tunned my car previously and its ctz. file

someone help me to get it in HPT as I faild to do it through the convert tools online. I'm not sure why and if the file its locked.

I go to write it to the car and I have enough credits to get specific license but the option not shown. see attached screenshot.Attachment 141006

I went to the Tune Repository page https://www.hptuners.com/my-account/tunerepository/

and I got a stock file for my lbz. Do you think I can write this file with no issue? Shall I change the vin and how?

Writing another vehicles file is a no no which you likely are aware. Though I've done it will no ill consequences but there are dangers. That said, make sure the OS and segments match. And yes, you'll blow 2 credits on the new file.

Can you use your current tune file to copy stock settings into? Or it won't let you pull it from the truck?

i have efilive and hpt. ctz is the efilive format isnt it ? i could possibly get something figured out with my lbz and read the file out with hpt.
