Shift strategy
Discuss shift points and response on supported TCU software. The aim is appropriate behaviour for the vehicle’s use.
T-Tronic Automotive | UK
Gearbox tuning that works with your engine.
Considering DSG or automatic gearbox software? We check the transmission type and condition before discussing shift behaviour and a calibration matched to your vehicle.
Service availability and price confirmed for your exact vehicle or unit.
Choose the right service
What do you need help with?
Engine and gearbox
Review the engine calibration and torque information alongside the transmission’s supported software and hardware limits.
Faults come first
Slip, harsh engagement, overheating or fault codes require diagnosis. TCU tuning is not a repair for worn clutches or mechatronic faults.
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
What we need
Registration or VIN, gearbox identification, TCU hardware/software numbers if available, service history, fault codes and engine modifications. DSG/S tronic, ZF, Mercedes or Ford names alone do not establish support.
After programming
Adaptations and learning procedures are performed or specified only where required for the exact transmission. We record what was changed and which on-vehicle checks remain necessary.
Your questions answered
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.
Can it be returned to standard?
Where a suitable original file or supported recovery route is available, restoration may be possible. We confirm this before work. Dealer software updates can overwrite a calibration; contact us before further programming.
What about insurance and warranty?
Tell your insurer about the planned modification and confirm cover before proceeding. Manufacturer or third-party warranty cover may be affected. Our written job scope explains the cover for our own work; this is not a warranty on the whole engine or gearbox.
Will higher torque limits make the gearbox stronger?
No. Software cannot increase the physical capacity of clutches, gears or cooling. Hardware condition and manufacturer limits remain relevant.
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.
