Frequently asked questions

Professional ECU and TCU calibration files, supplied as binary files for you to flash with your own tools. BRV Tuning does not carry out any physical hardware work.

Upload your original read in the client portal. Nothing is charged on upload. You pay when you download the finished file. Re-downloading a file you have already paid for is free.

Your original ECU or TCU read, the vehicle make, model, year and engine code, and a note of any hardware fitted, such as an upgraded intake, exhaust, turbo or intercooler. The more detail you give, the better the file matches the car.

Accounts are approved by BRV Tuning. The service is aimed at tuners, workshops and professional users.

Stage 1 car tuning files start from €65 ex VAT at the master file price.

Yes. Slave pricing (Tier E) is 40% off master file prices and applies to accounts ordering 100 or more files a month. Accounts ordering 10 to 99 files a month receive 10% to 30% off. See the pricing page.

All prices are in EUR and are ex VAT. VAT is added where it applies.

A Stage 1 file is a software-only calibration for a standard, unmodified engine. It changes fuelling, boost and timing targets within the limits of the standard hardware. Results vary by engine and car.

Stage 1 is for standard hardware. Stage 2 is for cars with supporting upgrades, such as an intake or exhaust. Stage 3 is for hybrid turbos and built engines, and is quoted per car because builds vary widely.

A checksum file corrects the checksum of a modified binary so it can be flashed. It does not change any performance calibration.

An add-on file is sold inside another job, so it costs less than ordering it on its own. For example, a DPF file ordered with a Stage 1 file.

A file can change what the ECU monitors. For example, a Stage 1 file can change boost and airflow targets, and the ECU may log an underboost or airflow fault if the car does not match the new targets. Read the stored codes before and after flashing so you can see what changed.

Emissions-related binary files are supplied for off-road, competition, agricultural and export use only. Using them on public roads is illegal in many countries. The professional customer is responsible for compliance and for informing the end user.

No. BRV Tuning supplies binary files only. Any hardware work is outside our service.

No. A DPF file changes how the ECU manages the filter. It does not clean soot or repair a damaged filter. A blocked or failed DPF needs inspection by a workshop. See the DPF off guide.

A DTC off file changes which faults the ECU reports. It is supplied for off-road, competition, agricultural and export use only. It must not be used to avoid an emissions inspection or to hide a fault on a road vehicle. See the DTC guide.

Share the code and the car details when you upload. We can tell you which files are relevant, but we cannot diagnose a fault remotely. Faults such as sensor or hardware failures need a workshop.

No. Support depends on the ECU and TCU that are read. Upload your read through the portal and we will confirm whether a file is available for it.
