I bought a stock computer for my 2015 Camaro out of a 15 Camaro when I click on to change vin it pops up to put vin in . I put the new vin and click commit and it saids saved successfully , then I go to click write computer and write it and when done writing I check if it put the new one in and its back to the old one. I did write calibrations only and write entire and neither worked. Am I doing something wrong? anyone know what it is? I figured if it commits and saves it successfully it shouldn't be a problem writing it. please help
another thing is when I save the file and open when not connected to the car it shows me the vin I changed it too, but when I read the pcm it still shows old vin.. IM very confused.
