🔥 BMW 320i G-Series (2021) | In-House ECU Unlock + Stage 1 Custom Dyno Tune + xHP Stage 3

Another post-June 2020 BMW successfully unlocked, tuned and transformed by us completely in-house 💪

This 2021 BMW 320i G-Series came to us for the complete package, starting with the locked ECU.

We carried out the ECU unlock in-house, followed by our Stage 1 custom dyno calibration and finished the package with xHP Stage 3 gearbox software.

📊 Stock: 184bhp / 335Nm
🔥 DC Tuned: 266bhp / 433Nm

That’s an increase of 82bhp and 98Nm from our custom Stage 1 calibration.

The difference on the road is huge. The B48 now has a much stronger mid-range, sharper throttle response and considerably more pull through the gears, transforming the 320i into a completely different car while retaining the smoothness and refinement needed for everyday driving.

The xHP Stage 3 gearbox software complements the engine calibration perfectly, sharpening the ZF8 with faster shifts, improved gear logic and optimised torque management to make much better use of the additional performance ⚡

Being able to carry out the post-June 2020 ECU unlocking in-house also means we can handle the process from ECU unlock through to the finished custom calibration under one roof.

Every vehicle is health checked, data logged and calibrated live on our linked 4WD dyno, allowing us to develop the tune around the individual vehicle rather than simply relying on an off-the-shelf file.

🔥 BMW 330e | Post-June 2020 ECU Unlock + Stage 1 Custom Dyno Tune

Another locked BMW transformed with our bespoke calibration package 💪

This BMW 330e arrived with a post-June 2020 locked ECU. The customer opted to have the ECU sent away for unlocking, which wasn’t an issue at all. We professionally removed, packaged and sealed the ECU before sending it to Autotuner on the Tuesday, and it was back with us by the Thursday, ready for custom calibration.

Once reinstalled, we developed a bespoke Stage 1 custom dyno tune, taking the car from 292bhp / 443Nm to an incredible 413bhp / 721Nm.

The transformation speaks for itself. Nearly 120bhp and almost 280Nm of additional torque completely change the way the 330e drives, delivering instant throttle response, relentless acceleration and effortless overtaking performance while maintaining smooth OEM level drivability.

Whether your BMW requires an in house unlock or a send away unlock, we can handle the entire process from start to finish, keeping everything simple and hassle free.

Every calibration is developed live on our linked 4WD dyno, with comprehensive diagnostics, health checks and live data logging throughout the process. Every tune is bespoke to the individual vehicle never an off the shelf file.

No generic files. No shortcuts. Just precision BMW tuning done properly.

🔥 BMW 545e (2021) | In-House ECU Unlock + Stage 1 Custom Dyno Tune

Another modern BMW pushed to the next level with our in-house ECU unlocking and Stage 1 custom dyno calibration 💪

This 2021 BMW 545e arrived producing 407bhp / 598Nm, and after successfully carrying out an in-house ECU unlock followed by our bespoke dyno calibration, it left delivering an incredible 503bhp / 872Nm.

The latest BMW ECUs are heavily protected, which is why having the ability to unlock and calibrate these vehicles entirely in-house is a huge advantage. No sending ECUs away. No lengthy waiting times. Just a complete service carried out under one roof.

The result is a completely transformed driving experience. Sharper throttle response, relentless acceleration and a massive increase in mid-range torque, while maintaining the smooth refinement expected from BMW’s plug-in hybrid performance platform.

This customer travelled all the way from Scotland to have us unlock and tune their 545e. We never take journeys like that for granted, and we’re incredibly grateful that customers continue to travel from across the UK for our specialist BMW tuning services.

Every calibration is developed live on our linked 4WD dyno, with comprehensive diagnostics, health checks and live data logging throughout the process. Every tune is bespoke to the individual vehicle never an off the shelf file.

No generic files. No compromises. Just precision BMW tuning done properly.

🔥 BMW 420i xDrive | Stage 1 Custom Dyno Tune + xHP Stage 3 Gearbox Software

Not every transformation is about chasing huge headline horsepower figures it’s about completely changing the way a car drives. 💪

This BMW 420i xDrive arrived producing 178bhp / 288Nm, and after our Stage 1 custom dyno calibration together with xHP Stage 3 gearbox software, it left producing an impressive 276bhp / 445Nm.

That’s nearly 100bhp and over 150Nm gained from a bespoke calibration designed specifically for this vehicle.

The difference behind the wheel is immediate. The B48 engine comes alive with sharper throttle response, a much broader torque curve and strong, effortless acceleration throughout the rev range. Combined with BMW’s xDrive system, the extra performance is delivered confidently in all weather conditions.

Adding xHP Stage 3 completes the package. The ZF8 gearbox benefits from quicker shifts, improved shift strategy and optimised torque management, allowing the drivetrain to make full use of the additional power while maintaining the smoothness expected from a BMW.

Every vehicle we tune is calibrated live on our linked 4WD dyno, with comprehensive diagnostics, health checks and live data logging carried out before, during and after the calibration process.

No off the shelf files. No guesswork. Just bespoke calibration built around your vehicle.

🔥 BMW M240i | Stage 1 Custom Dyno Tune + xHP Stage 3 Gearbox Software

Another B58-powered BMW transformed with our complete engine and gearbox calibration package 💪

This BMW M240i arrived producing 342bhp / 515Nm, and after our Stage 1 custom dyno calibration combined with xHP Stage 3 gearbox tuning, it left delivering an impressive 429bhp / 615Nm.

The B58 engine is one of BMW’s best tuning platforms, responding exceptionally well to a bespoke calibration. The result is instant throttle response, relentless acceleration and a huge increase in mid-range torque, making the car feel significantly more urgent throughout the rev range while maintaining OEM refinement.

With xHP Stage 3 installed, the ZF8 gearbox is transformed. Shift speeds are noticeably quicker, gear selection becomes more aggressive when required and torque management is optimised to fully utilise the increased power. The result is a drivetrain that feels sharper, faster and far more engaging to drive ⚡

Every vehicle is calibrated live on our linked 4WD dyno, with full diagnostics, health checks and live data logging carried out throughout the process. Every calibration is bespoke to the individual vehicle, ensuring safe, consistent and repeatable results.

No generic files. No compromises. Just precision BMW tuning done properly.
