Engine & Gearbox Tuning in Sheffield
Custom engine tuning through ECU remapping, with gearbox tuning also available for Volkswagen, Audi, SEAT, CUPRA, Škoda and BMW vehicles. From Stage 1 software to cars with upgraded turbos, we develop the setup around your vehicle and goals.
All listed prices include VAT. Vehicle suitability and available features vary by ECU/TCU and hardware specification.
Developed in-house
Engine software developed by JBM, not simply supplied as a generic file.
In-house dyno
Development, logging and validation available at our Sheffield workshop.
Engine & gearbox
Engine and gearbox software designed to work together.
Specialist knowledge
Focused heavily on VAG and BMW performance platforms, including MQB and 2.5 TFSI RS applications.
Custom tuning
Tuning matched to your car.
ECU remapping changes the software that controls your engine. We develop the settings around your engine, fuel, hardware upgrades and how you use the car. This detailed development work is known as calibration.
Where required, we also tune the gearbox software so torque management, gear changes and clutch pressure suit the engine setup.
- Improved torque and power delivery
- Sharper, more consistent throttle response
- Calibration matched to hardware upgrades
- Engine and gearbox tuning available
- Logging, diagnostics and dyno validation where appropriate

Advanced MQB tuning
More than a conventional Stage 1 or Stage 2 remap. On supported MQB vehicles, our custom calibration can incorporate switchable maps, security functions, launch strategies, flex-fuel, manual-car features and advanced traction control alongside the core engine tune.
01
Multi-map switching
Choose between multiple calibrations from the vehicle controls, allowing different power, fuel or driving configurations where supported.
02
Immobiliser / non-start map
An additional switchable security setting can be configured so the engine will not start while the immobiliser map is selected.
03
Rolling launch / anti-lag
Advanced rolling boost strategy for suitable vehicles and hardware configurations.
04
Boosted launch control
Static launch calibration with a boost-building strategy where the vehicle and hardware allow.
05
Flex-fuel
Ethanol-content based calibration strategies available for selected compatible MQB setups with the required hardware.
06
FWD boost-by-gear
Boost and torque can be calibrated by gear to improve traction and usability through the lower gears, particularly gears 1-3.
07
Advanced traction strategy
Boost-by-gear works well in most conditions, but when grip changes suddenly, for example if a wheel becomes unloaded over a bump or the road/track is damp, the advanced traction strategy can react dynamically and manage torque far more effectively than the OEM settings.
08
Flat-foot shifting
FFS functionality for supported manual-transmission cars, allowing full-throttle gear changes where configured.
09
Clutch-start bypass
For supported manual cars with an uprated clutch, the clutch-to-start requirement can be disabled to avoid unnecessary crankshaft thrust-bearing / thrust-washer load during starting.
Feature availability depends on vehicle software, transmission, hardware and intended use. Some functions are intended for off-road / motorsport use only. We will confirm compatibility and available functions before calibration.

BMW MG1 / MD1 ECU unlocking
In-house ECU unlocking for custom or OTS tuning.
We bench unlock supported BMW Bosch MG1 and MD1 ECUs in-house, providing the ECU access required for tuning. Once unlocked, the car can be calibrated using our own custom ECU software, or compatible off-the-shelf maps from MHD or Bootmod3.
The unlock is the access stage rather than the calibration itself. From there, you can choose a JBM custom calibration developed around your vehicle and hardware, or use a compatible MHD or Bootmod3 OTS map. Already have a software licence? No problem, the unlock can also be carried out as a standalone in-house bench service. Supported encrypted 2020+ MG1 / MD1 ECUs can be unlocked without sending the ECU away.

ECU and flashing-platform support varies by vehicle, ECU hardware/software version and production date. Supported BMW MG1 / MD1 applications, including supported encrypted 2020+ ECUs, can be bench unlocked in-house. The unlock is £150 as a standalone service or £100 when a compatible MHD or Bootmod3 licence is purchased through JBM. After unlocking, you can use a JBM custom calibration or a compatible OTS map. Contact us with your registration or VIN before booking so we can confirm ECU compatibility and the best tuning route for the vehicle.
The JBM process
A calibration should be verified, not guessed.
The exact process varies with the vehicle and level of modification, but the principle remains the same.
01
Health check
Diagnostics and initial assessment before performance calibration begins.
02
Baseline data
Logging and/or dyno testing where appropriate to establish how the car is currently operating.
03
Calibration
Software developed around the vehicle, hardware, fuel and required driving characteristics.
04
Validation
Key engine and torque-control parameters checked and refined rather than relying on headline power alone.
05
Handover
Final checks plus an explanation of the setup, features and any relevant operating requirements.
Common questions
Before you book.
Is the engine tuning carried out in-house?
Yes. JBM's engine calibration work is carried out in-house and can be tailored around modified hardware rather than relying solely on an off-the-shelf file.
Do I need gearbox software as well?
Not every vehicle requires it, but transmission calibration can be important where additional engine torque exceeds the original TCU strategy or where shift behaviour, clutch pressure and torque management need to be optimised.
Can you tune a modified or hybrid-turbo car?
Yes. Heavily modified cars are one of the main reasons to use bespoke calibration. Send us the full hardware specification when enquiring so we can quote the correct level of work.
Are advanced features available on every vehicle?
No. Launch strategies, map switching, flat-foot shifting and other advanced features depend on ECU software, transmission and hardware. Availability is confirmed case-by-case.
What information should I send for a quote?
Your vehicle registration, current hardware modifications, fuel used, transmission type and what you want from the car. For unusual builds, include as much detail as possible.
