Professional ECU Tuning Services
Custom ECU file services prepared by our team — performance tuning, emission system removal, fault code clearing and more. Based on your original ECU file, delivered ready to flash with your favorite tool.
What we do
GTBackup specializes in original ECU files and professional custom modifications for diesel and petrol vehicles. We work with all major ECU manufacturers — Bosch, Continental, Delphi, Siemens, Magneti Marelli, Denso — and support cars, vans, trucks, motorcycles, agricultural machines and marine engines.

Frequently asked questions
How long does it take to receive my tuned file?
Standard turnaround is 24 to 48 hours after we receive your original file. Urgent requests can be processed within a few hours — contact us for priority handling.
What do I need to send to get a quote?
To prepare your custom file, we need: vehicle VIN, ECU label photo (showing part numbers), your reading tool (KESS, KTAG, etc.), and the services you want. Once your ORI file is read, send it to us with your order.
Is the modification reversible?
Yes. We provide both the modified file and your original (ORI) file. You can revert to factory state at any time by flashing the ORI back to your ECU.
Do you offer Stage 2 or Stage 3 tuning?
No. We focus on Stage 1 performance, emission system delete and DTC services. Stage 2 and Stage 3 require hardware modifications and dyno calibration that fall outside our service scope.
What if my ECU is not listed?
Our database covers 99% of modern ECUs (Bosch, Continental, Delphi, Magneti Marelli, Denso, Siemens). Contact us with your VIN and ECU label — we’ll confirm support within hours.
