BMW 330e G21 Touring Stage 1, ECU Unlock & Gearbox Tune

This 2022 BMW G21 330e Touring had our very popular 330e package: Stage 1 ECU calibration, a same-day ECU unlock and a ZF 8HP gearbox tune. Combined output rose from 292hp and 420Nm to around 400hp and 700Nm, a gain of 108hp and 280Nm.

How it drives now

The B48 2.0-litre turbo petrol and the plug-in hybrid system respond very well to tuning. Acceleration, mid-range pulling power and response are all transformed, and the progressive power delivery means it is just as enjoyable day to day.

Unlocking the MG1 on site

Like many newer BMWs, this car has a locked Bosch MG1CS201 ECU. With our mobile bench unlocking equipment, the ECU was removed, unlocked and refitted on site before the calibration was completed through the OBD port, all in one appointment.

What was included

  • Same-day Bosch MG1CS201 bench unlock
  • Stage 1 ECU calibration
  • ZF 8HP gearbox calibration, for sharper shifts and torque management
  • Speed limiter solution
  • BMW Sports Display recalibration
  • Gear display activation
  • Advanced dealer-level diagnostics before and after

Can you tune a 330e at my home?

Yes. Supported newer BMW ECUs can be unlocked and tuned at your home or workplace in one appointment, across Bristol, North Somerset, Somerset and South Wales.
