E9x M3 DCT Final Drive (Differential Swap) Remote Coding

ECUWorx can remotely flash your DCT control unit (mechatronic unit) with custom DCT software that will resolve shifting issues created when final drive changes are made to your E9x M3.

Popular changes are 3.62, 3.91 and 4.10. We can cater for each, just please let us know in the notes field when ordering.

The final drive flash will not interfere with engine maps / tuning.

An ECUWorx Flashing Cable for E60 M5, E65 M6 and E92 M3, along with a Windows laptop and an internet connection is required for this service.

A non ECUWorx Flashing cable may result in a failed flash!
