Needed before some tunes can be flashed
Many 2020-on BMWs have a locked ECU that has to be unlocked before any tune can be flashed, with MHD, bootmod3 or a custom map. We unlock it on the bench, in house, the same day. No shipping it abroad and no days off the road.
Can't get to us? Post your ECU with next-day delivery. We unlock it and send it back the same day.
