Micro-Tech has been remanufacturing, flash programming, and recalibrating OBD-II ECMs since the beginning. We believe our service and technology is the best in the industry. Apparently so do some of our competitors, as many of the top names in electronics use Micro-Tech to supplement their own programs.

Another feature of the GM unit is that a new or remanufactured unit can be flash programmed to become another part number. There are a number of companies that manufacture flash programming equipment and are available to the aftermarket. However this is not a job for the amateur, as the ECM can be destroyed if the wrong numbers or programs are accidentally entered.
