The Jetta/Taos 1.5T ECU (MG1CS011) is now unlocked for tuning!

The latest 1.5T Bosch MG1CS011 ECU with advanced encryption, found in the US/Canada Jetta, Taos, and wide range of other Audi, Cupra, Ford, Seat, Skoda, and VW Vehicles is now available for a simple and quick mail-in unlock.

If you're new to AutoTuner, we make professional universal programming tools and services for tuners around the world. With this latest unlock your favorite tuner can now write a custom or off the shelf tune for your engine! They can flash it with the AutoTuner Tool over Bench, and OBD. Our readouts include both software and calibration. On the bench you'll get a normal read and backup creation ability. On OBD you'll get a virtual read and back to stock functionality. The reading / writing process is quick. 2 minute read, 1 minute write on bench and a 2 minute write on OBD. Of course, checksums are automatically corrected.
