Tuning files for workshops: the calibrated file written on your read
You send the ECU read, we send back the file: written by a technician on the original map, checked against the stock file and matched to the exact hardware and software version of the vehicle in front of you. No subscription, credits only when you need them.
How it works
Open a free account
Registration takes a minute and costs nothing. The account is for workshops and installers.
Buy credits
One credit is one euro. You buy them securely and spend them only when you order a file.
Upload the read
Read the ECU with your tool, OBD, bench or boot, and upload the file with the vehicle details and the options you want.
Download the file
Usually in under an hour during working hours. You write it with the same tool you used to read.
What we write
Calibrations on the original map, not generic patches. Every file is built for the specific engine, gearbox and ECU software version, and keeps the factory safety strategies in place.
Performance
From a standard car to a heavily modified engine, plus trucks, tractors and automatic gearboxes.
- Stage 1 carsOptimisation on a completely standard vehicle: no mechanical change, torque delivery improved across the usable rev range.
- Stage 2 carsFor vehicles that already carry hardware changes, typically exhaust or intake. The map is written around the parts actually fitted.
- Stage 3 carsUpgraded turbo, injectors, intercooler: handled case by case, with the specification agreed before the work starts.
- Trucks and agricultural machineryStage 1 for commercial vehicles, tractors and industrial engines, where low-rev torque and consumption matter more than peak power.
- Gearbox Stage 1 and 2DSG and automatic transmissions: torque limiters, shift speed, clamping pressure and launch behaviour, aligned to the engine calibration.
- E85 flexfuelFuelling and ignition adapted to ethanol blends.
ECU and TCU services
The jobs a workshop runs into every week, the ones that keep a car on the ramp when the original file or the tooling is missing.
- IMMO OFF, ECU and TCU cloningImmobiliser handling and virgin-unit cloning when a control unit is replaced.
- Back to stockReturn to the factory calibration, from our archive of stock files or from your own read.
- Airbag crash dataCrash records cleared from the airbag control unit after a repair.
- File checkSend us a modified file and we tell you what has been changed in it before you write it.
- TDI injector knock patchCorrection for injector knocking on TDI engines, supplied with the Stage 1 calibration.
- EDC17C69 white smokeSpecific fix for the FCA white smoke fault on EDC17C69 control units.
Diagnostics and emissions systems
Work on the after-treatment systems and on the OBD monitoring that goes with them, evaluated case by case on the specific control unit.
- After-treatment systemsDPF/FAP, EGR, AdBlue/SCR, swirl flaps and lambda circuits.
- OBD emissions monitoringCorrection of readiness and monitoring behaviour where the diagnosis calls for it.
- Oil pressure strategySolution for oil pressure management faults on the engines where this is a known pattern.
A note on emissions equipment
Removing or disabling after-treatment devices is not permitted on vehicles used on public roads in the European Union and in many other countries. These services are supplied for motorsport use and for vehicles used on private land only; the workshop is responsible for how the file is used.
Prices in credits
One credit is one euro. Prices refer to the electronic work only: downpipes, filters and labour are charged by the workshop. Options are added to a Stage 1 or Stage 2 file, several of them at no extra cost on Stage 2 and 3.

The archive behind every file
A file is only as good as the reference it is written against. The service runs on an ECU catalogue and on an archive of stock reads that grows with every job.
- 22,968vehicles in the ECU catalogue, with hardware, software and update numbers
- 17,863configurations with measured power and torque figures
- 170manufacturers covered: cars, vans, trucks, bikes, tractors
- 54,000+stock files listed by make in the original files archive
- 8languages on the platform
Who writes the files
MasterTuning has worked on engine electronics for over twenty years: design, optimisation and development of the firmware that runs injection control units for petrol, diesel, LPG and CNG engines.
Calibrations are developed and tested in-house. Performance, reliability and consumption tests run on a PowerScan dynamometer with instruments for fuelling, temperatures, boost pressure and emissions, alongside current diagnostic systems.
The same technicians answer the requests that come through the platform: a file is not generated, it is written and checked before it goes back to you.

Frequently asked questions
What is a tuning file and who can order one?
It is the calibration file written on your ECU read: Stage 1, 2 or 3, or a specific job such as IMMO OFF, back to stock or a file check. The service is for workshops and installers with an account on the platform; owners with a car to tune go to a MasterTuning centre.
How long does it take to get the file?
Usually under an hour during working hours. Special jobs, such as a Stage 3 or a repair, are agreed beforehand and can take longer.
How much does a file cost?
You pay in credits and one credit is one euro. A Stage 1 for cars costs 100 credits, a Stage 3 250, a stock file 30, a file check 20. Options (EGR, DTC, AdBlue, launch control and the others) are added to the base file. Prices refer to the electronic work only.
Which tool should I use to read the ECU?
Any professional tool that produces a complete read of the control unit, via OBD, bench or boot: for example Flex or The Genius, which you also find in our shop. The file comes back ready to be written with the same tool you used to read.
Does the file keep the factory engine protections?
Yes. Calibrations are written on the original map and keep the factory safety strategies: temperature, pressure and torque limits stay in place, moved only where the engine allows it.
Are DPF, EGR and AdBlue deactivations legal?
Removing or disabling after-treatment systems is not permitted on vehicles used on public roads in the European Union and in many other countries. These services are supplied for motorsport use and for vehicles used on private land, and the workshop is responsible for how the file is used.
Can I have a file modified by someone else checked?
Yes: the file check service costs 20 credits. You send us the file and we tell you what has been changed compared with the original, before you write it to the car.
