BMW M235i Stage 2 ECU Calibration

Engine Tune:

Stock 326 hp / 450 Nm +89 hp
Stage 2 415 hp / 620 Nm +170 Nm

The M235i already delivers strong performance from the N55 3.0 turbocharged engine, but with the supporting Stage 2 hardware there is significant scope beyond the factory calibration. Our Stage 2 tune delivers considerably stronger mid-range torque and improved power throughout the rev range, while still maintaining the smooth, easy-to-drive BMW character that makes the M235i such a capable everyday performance car.

This vehicle also received several additional calibration options, including cold start solution, exhaust flaps open in Sport mode, speed limiter solution and BMW Sports Display recalibration.

This M235i runs a Bosch MEVD17.2.G ECU and was safely calibrated via AutoTuner OBD, with the original ECU software securely read and backed up prior to programming.

Included:
• Cold start solution
• Exhaust flaps open in Sport
• Speed limiter solution
• BMW Sports dial recalibration
• Original ECU file securely backed up

Dealer-level diagnostics carried out before and after tuning.

BMW X5 G05 xDrive30d 265hp Stage 1 ECU & Gearbox Tune

Engine Tune:

Stock 265 hp / 620 Nm
Stage 1 310 hp / 720 Nm
+45 hp / +100 Nm

The G05 X5 xDrive30d already delivers strong torque and effortless performance from the B57 3.0 diesel, but there is plenty of scope within the factory calibration. Our Stage 1 tune improves throttle response and significantly strengthens the mid-range, giving the X5 a noticeably more responsive and effortless drive while retaining its smooth OEM character.

This vehicle also received a gearbox calibration to complement the increased torque, featuring optimised D & S shift points, faster shifts, quicker paddle response, optimised torque converter lockup, raised torque limits to suit the tuned engine and gear display activation.

This G05 runs a Bosch MD1CP002 ECU, which was first unlocked via AutoTuner Bench to enable OBD read and write protocols. Once unlocked, the ECU calibration was safely completed via AutoTuner OBD, allowing future programming through the diagnostic port without removing the ECU again.

Included:
• Speed limiter removed
• Original ECU file securely backed up
• ECU bench unlock for OBD programming

BMW 435i Gearbox Calibration

The BMW 435i already delivers strong performance from its 3.0-litre N55 engine, but the factory ZF 8-speed automatic transmission calibration can be further optimised to provide a sharper, more responsive driving experience.

This vehicle received our ZF8 gearbox calibration, programmed directly through the OBD port using AutoTuner. The calibration improves shift behaviour and makes better use of the N55’s power and torque, while retaining smooth, OEM-like drivability during normal driving.

Gearbox Calibration Includes:
• Optimised D & S shift points for better acceleration in part and full throttle situations
• Faster shifts overall
• Faster paddle response time
• Optimised Torque Converter Lockup
• Torque limits raised to match tuned engine
• Gear display activation

The original TCU software was securely read and backed up before programming, allowing the vehicle to be returned to standard if required.

Engine Tune:
Stock 184 hp / 290 Nm
Stage 1 260 hp / 420 Nm
+76 hp / +130 Nm

The BMW G20 320i is an excellent all-round performer, but our professionally developed Stage 1 ECU calibration transforms the way the B48 engine delivers its power. With significantly improved throttle response, stronger mid-range torque and smoother power delivery, the car feels far more responsive while retaining OEM-like drivability and reliability.

As this vehicle is equipped with the locked Bosch MG1CS01 ECU, a professional bench unlock was first carried out before programming.

The Ford Fiesta 1.6 TDCi is renowned for its excellent fuel economy and reliability, but our professionally developed Stage 1 ECU calibration unlocks noticeably stronger performance throughout the rev range. With improved throttle response, increased mid-range torque and smoother power delivery, the Fiesta feels far more responsive in everyday driving while maintaining OEM-like refinement and reliability.

This particular Fiesta was professionally calibrated via Magic Motorsport Flex OBD using the Bosch EDC17C10 ECU, meaning the entire process was completed through the diagnostic port with no ECU removal required.
