BMW M235i N55 Stage 2 ECU Calibration

This BMW M235i went from 326hp and 450Nm to 415hp and 620Nm with our Stage 2 ECU calibration, a gain of 89hp and 170Nm, written around its supporting Stage 2 hardware.

The N55 M235i on Stage 2

The M235i's N55 3.0-litre turbocharged engine is strong as standard, but with supporting Stage 2 hardware there is a lot more available beyond the factory calibration. Our Stage 2 tune gives considerably stronger mid-range torque and more power throughout the rev range, while keeping the smooth, easy-to-drive character that makes the M235i such a good everyday performance car.

Extra calibration options

  • Cold start solution
  • Exhaust flaps open in Sport mode
  • Speed limiter solution
  • BMW Sports Display recalibration
  • Original ECU file backed up

ECU and tools

This M235i runs a Bosch MEVD17.2.G ECU and was calibrated through the diagnostic port with AutoTuner. Dealer-level diagnostics were carried out before and after tuning.

What is the difference between Stage 1 and Stage 2 on an M235i?

Stage 1 is calibrated for a standard car. Stage 2 is written for supporting hardware such as intake, intercooler or exhaust upgrades, which lets the software safely ask more of the engine. We tune at your home or workplace across Bristol, North Somerset, Somerset and South Wales.

  • Dealer-level diagnostics before and after
  • Fully mobile, at home or work
  • Lifetime software warranty and support
