DIGISOFT / MANUAL FILE SERVICE
OPF / GPF Off
Gasoline particulate filter calibration requests.
What we do
We assess OPF / GPF Off file-service requests for the exact ECU software and gasoline particulate filter application. We confirm suitability and the agreed calibration scope before processing an eligible request.
Application review
Availability is confirmed from the original file, control-unit software and intended use. A listed service does not imply support for every vehicle or ECU.
Emissions, noise and vehicle-limit changes are assessed only for applications where the requested work is permitted. No road-use approval or emissions-inspection result is implied. Confirm applicable requirements before requesting a modification.

One file, up to 20 MB. An original file is required for mileage correction; files are optional for other enquiries. Work is performed manually by the Digisoft team. Submitting saves a request and may open a prepared WhatsApp message; it does not send that WhatsApp message automatically.
