I just recently bought an 98' M3 supercharged and intercooled with the OBD1 conversion, but I now have to get it smogged in Arizona. So I would like to know what exactly do I have to do to get it back to OBD2 to get it smogged, OR is there a way around all this mess. Thanks for the info.
keep it regesterted out of state, i hate obdII, if you want a real answer you need a complete harness and all of the sensors/computers, plus restoring whatever that may of been done to the car's systems to make it work with a obdI harness
all america wants is cold beer warm cat and a place to take a poop with a door on it
