​Hello,
​I'm working on a tune for a GM E55 PCM, which is only Flash-Supported by EFILive. I successfully had EFILive Support convert my .ctz read into a raw .bin file for third-party editing, and I will be using EFILive for flashing the modified file back.
​I am planning to edit the raw .bin file using TunerPro RT, but I am currently searching for the correct definition file.
​I am urgently looking for the TunerPro XDF file that corresponds to Operating System (OS) ID:
​12623520
​If anyone in the community has this XDF file, or knows where it can be downloaded, please share. Any assistance or direction would be greatly appreciated!
​Thank you!
