Unlocking Hybrid Performance Without Compromise

The BMW 330e combines turbocharged petrol power with electric assistance, offering impressive efficiency and everyday usability. From the factory, however, much of the platform’s potential is held back by conservative ECU and gearbox calibrations.

At MTechTuning, our Stage 1 ECU remap and ZF gearbox tune for the BMW 330e unlocks that hidden performance, delivering a substantial increase in combined system power and torque while maintaining smooth, factory-like drivability.



BMW 330e Performance Figures – Stock vs Stage 1

Engine & Hybrid Tune

Stock output:
292hp / 420Nm

Stage 1 output:
400hp / 700Nm

Performance gain:
+108hp / +280Nm

These gains transform how the 330e drives, particularly in the mid-range where the electric motor and petrol engine work together most effectively.

What Does the BMW 330e Stage 1 Remap Change?

Our Stage 1 ECU remap is designed to enhance performance without compromising reliability or refinement.

Drivers can expect:

• Sharper throttle response
• Stronger mid-range acceleration
• Noticeably improved overtaking performance
• Smoother and more responsive power delivery
• Retained comfort and usability for daily driving

Performance improvements are felt in both electric-assisted driving and petrol-only operation, making the car more engaging in all conditions.

Bosch MG1 ECU Unlock – New Tuning Capability

The BMW 330e is equipped with a Bosch MG1 ECU, which is factory locked on many newer models. Until recently, this prevented proper tuning on certain production dates.

Using a newly supported ECU unlock protocol, we’re now able to safely and reliably tune these newer BMW hybrid ECUs. This unlock process allows full access for professional calibration while retaining factory safety systems and diagnostic functionality.

This development opens the door for true Stage 1 tuning on modern BMW hybrid platforms, rather than limited or compromised solutions.

ZF 8-Speed Automatic Gearbox Tune

With torque increasing to 700Nm, recalibrating the gearbox is essential to ensure the drivetrain works as a cohesive system.

Our bespoke ZF 8-speed automatic gearbox tune includes:

• Faster and smoother gear changes
• Improved shift logic under load
• Enhanced torque management
• More responsive behaviour in Comfort and Sport modes

The result is a gearbox that makes full use of the additional power, improving both performance and refinement.

Included Options with the BMW 330e Stage 1 Package

As part of our BMW 330e Stage 1 tuning package, we also include:

• Speed limiter removal
• Sports display recalibration
• Gear display activation

All work is supported by advanced dealer-level diagnostics carried out before and after tuning, including hybrid system and drivetrain checks, ensuring everything operates exactly as intended.

Fully Mobile BMW 330e Tuning

We offer a fully mobile service, meaning the ECU and gearbox tuning can be completed at your home or workplace at no extra cost. This makes upgrading your BMW 330e both convenient and hassle-free.
