BMW DME ECU OBD Unlock for OBD2 Tuning - MG1 - B46 B48 B58 S63 S58

BMW and Toyota Supra - Bosch MG1 DME OBD2 UNLOCK service.

Most newer BMWs with the later MG1 DMEs are locked by the latest BMW software updates, which prevent tuning software like MHD Bootmod3 MG-Flasher from being installed by the customer via the OBD2 port. This service will unlock the OBD2 port and allow the DME to be flashed with a tune of your choice. We make a full 100% original DME backup before the unlock, so it can always be restored to original data.

We have a special harness that we built, that allows us to quickly and safely to connect to your DME with original OEM connectors. So there's no chance of bent pins or damage to pins, this is very crucial as the MG1 DME pins are very small and very close together. A lot of cheaper inexperienced companies can damage, bend or break off your pin, or short the pins out if they're not careful. Our special harness we built, not only saves time but also saves and protects your DME as well. 

For this DME UNLOCK service, you will have to send in the original DME. You will need to remove it from your car, confirm it's not too new, place the purchase order here, and then print the tuning form. Place the filled-out repair form and your DME in a box, and ship it to us for unlock.

If you have any questions, or concerns or want to confirm that we can unlock your DME, please send us an email and a picture of the ECU stickers.
