As they say, never give up. Whenever you face a brick wall, frustrated with nowhere to turn, eat some food, get some rest, and then tread on some more. The ECM VIN and PIN change via DPS have had me baffled for some time. Today I had another go at it, and after drinking seven cans of Redbull and a lot of thinking, I solved the puzzle/hack.
Changing the VIN and PIN in a used secondhand GM ECM module is very important for those who want to recycle GM ECM modules. With this solution, you can achieve just that. At this moment, it only works for 2-Byte seed ECM modules. I have some 5-Byte ECM coming from the USA. Hopefully, I'll figure out the 5-Byte ECM VIN change with DPS when they arrive.
Watch the video below to see how quickly you can change the VIN in the ECM.
