I searched but only found a 1 year old thread. I just bought a 2021 Blazer 2LT with the 3.6 engine. I really want to disable the AFM on it. I guess I'm not trying to start a discussion on the pros and cons of doing this. I know a company called "Range" makes a device that plugs into the OBD-II port and prevents the AFM from functioning. I couldn't find one on their website for my vehicle. So I sent them a message asking about it and they replied that they don't have one for my car. I replied asking them to hurry up and produce one. In the mean time, anyone around here use a device to disable AFM? I think I found somewhere where someone claimed they are using the Range device and it works on our Blazers?
