Mobile BMW work by MTechTuning, with dealer-level diagnostics before and after.

BMW M4 G82 Competition MG1 ECU Unlock, Ready for MHD

This BMW G82 M4 Competition had its MG1 ECU unlocked in-house so the customer could use MHD for their own tuning. We carried out the unlock and verification only, with no ECU mail-in, no days waiting and no second appointment.

The unlock process

  • Full diagnostics and vehicle health check
  • MG1 ECU type verified through the OBD port
  • ECU removed and unlocked directly on the bench
  • OBD verification confirming the ECU is unlocked and ready for tuning

Can you unlock my BMW for MHD?

Yes, on supported MG1 ECUs. Once unlocked, this customer could carry straight on with their own MHD setup. We are fully mobile across Bristol, North Somerset, Somerset and South Wales, with advanced dealer-level diagnostics included.

About this job

What the work involved

Its Bosch ECU was locked against tuning, so the first step was to unlock it. The original software was saved before any changes were made.

How we carried it out

  • Diagnostic scan for stored faults before any work
  • Stabilised power supply connected while programming
  • Original software read and saved, so the car can be returned to standard
  • Calibration written, then the car checked again afterwards

Thinking about the same for your BMW?

We come to you from our Weston-super-Mare base, across Bristol, Somerset, Gloucestershire, Wiltshire, South Wales and parts of Devon and Dorset. Results depend on the exact car, so we confirm what suits yours before quoting.
