Been self teaching on my own how to first scan and diagnose different cars I've owned, then realized that if I could edit the ecu I could have fixed some problems with those cars instead of selling them....
Now I have a 2016 Cadillac with the Delphi E80 ECU, which i have learned the newer the model the harder it is to customize and download or flash. Although I have had some success with online GM SPS2 updates and also the GM DPS system, I just do not yet know how to make my own archive files so that I can user tunerpro for editing and then reflash the car. Maybe one day, learn the Type 4 applicatipons that the guide speaks of.
And yes I've seen the camera page online that has tutorials for hundreds and hundreds of dollars, but I'm poor and cant afford his prices. So I learn by trial and error. My secondary ECU to really practice on should be here soon, so I dont mess up my daily driver...
