BMW 330e G20 Stage 1, ECU Unlock & Gearbox Tune

Another G20 330e with our full package — this 2022 car went from a combined 292hp and 420Nm to around 400hp and 700Nm, up 108hp and 280Nm, with its locked ECU unlocked and the ZF 8HP gearbox tuned in a single visit.

Hybrid power, properly calibrated

The 330e pairs BMW's B48 2.0-litre turbo petrol engine with a plug-in hybrid system, which gives it a lot of potential. The calibration transforms acceleration, mid-range pull and response, while the power delivery stays smooth and progressive enough for everyday driving.

One visit, no ECU mail-in

This car had a locked Bosch MG1CS201 ECU. We removed and unlocked it at the customer's location with our mobile bench equipment, refitted it and finished the Stage 1 calibration through the OBD port, with no return appointment needed.

Work carried out

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

Why tune the gearbox as well?

The ZF 8HP tune improves shift response and torque management so the gearbox keeps up with the extra performance. We are fully mobile across Bristol, North Somerset, Somerset and South Wales.
