Engine remapping
Stage 1 for suitable standard vehicles; Stage 2 and custom projects after a hardware review.

ECU software & tuning. Choose the right route.
More usable performance, a replacement ECU that needs matching, or a failed software update? These are different jobs. Start with your symptoms or your goal and we will confirm the right service.

Gearbox tuning
TCU software for supported transmissions, matched to the vehicle and engine torque.
ECU cloning
Transfer supported data from the original ECU into a compatible replacement. Compatibility first.
Programming & recovery
Assessment after a failed flash, corrupted software or replacement-module installation.
Emissions fault diagnosis
DPF, EGR and AdBlue/SCR faults investigated with the equipment retained and functional.
Workshop software support
Trade enquiries with ECU identifiers, original read details and a clear job specification.
Understanding the result
More than a peak power number
Illustration only. These curves are not measured results, a vehicle quotation or a promise of gains.
Baseline illustrationExample calibrated shape
A useful calibration considers how torque builds through the rev range, not just the highest number. We discuss realistic targets for your engine, fuel, gearbox and condition before booking. Actual power and torque require a suitable measurement; a bench flash alone cannot confirm them.
A clear process
How it works
Identify the vehicle
Send the registration or VIN, engine, gearbox, existing modifications and your goal. ECU type and software version determine which methods are available.
Check the condition
We agree the diagnostic checks needed before calibration. Existing starting, boost, fuelling, temperature or transmission faults must be resolved first.
Agree the calibration
We confirm the supported read/write method, backup or recovery route, scope and price. The intended fuel and any supporting hardware are part of the specification.
Write, check and document
On supported units we write and verify the software, then agree the appropriate vehicle checks. You receive a record of the work and any remaining checks or limitations.
Before you book
Performance or repair?
For a healthy car, explain the response or performance you want. For warning lights, limp mode or no-start, send the symptoms and scan first. Changing software without establishing the cause can leave the original problem unresolved.
Local and UK-wide
Vehicle work is arranged by mobile appointment where suitable around Mansfield and Nottingham. Supported module work is available by post. Parts drop-off is available by prior arrangement. Contact us to agree a handover time.
Your questions answered
How much extra power will my car make?
That depends on the exact engine, ECU software, fuel, hardware and condition. Send those details for an assessment. We do not apply a universal percentage or present illustrative curves as your dyno result.
Can I send just the ECU?
Some supported ECU work can be completed by post. Reading or writing the ECU on the bench does not test the engine, drivetrain or road behaviour. We agree the vehicle checks and any follow-up work before accepting the unit.
Does tuning repair a fault?
No. A remap is not a repair for low fuel pressure, boost leaks, worn components or faulty emissions systems. Diagnostic work comes first if the vehicle has symptoms.
Start with your vehicle or module details
Send clear label photos, the vehicle details and a short description of the problem. We confirm the appropriate service, price and next steps.
