FAQ
File service questions
What is a file service for workshops?
The workshop reads the ECU with its slave tool, uploads the file to our portal and we prepare modified software that the workshop writes back to the vehicle.
How fast do I get the modified file?
During business hours (Mon – Fri 8:00 – 17:00) usually within 40 minutes. Complex and custom work is agreed in advance.
What if a car has an issue after tuning?
Our files are tested and we stand behind them. If an issue ever comes up, we always solve it and never refuse to fix the file.
How do I pay for files?
With credits in the portal. The credit and service pricelist is available after login; new members get a 0.3 credit bonus on their first purchase.
Do you do DPF, EGR or AdBlue off?
No. We do not disable or remove emission systems. We only carry out legal DPF, EGR and AdBlue repairs.
