Is this service for public-road vehicles?

These services are intended only for motorsport, off-road, export, test or other legally permitted use. The customer is responsible for local law, inspection and insurance consequences.

Why is support file-dependent?

Aftertreatment strategies differ by ECU, software version and hardware state. We check the original file before confirming what can be prepared safely.

What should I mention in the order?

Describe the hardware condition, current faults, sensors, warning lights and intended use. Clear information helps us prepare the right file faster.

NOX OFF

Order NOx Off for supported ECU software where NOx monitoring or NOx-system diagnostics need to match a permitted setup. WEREMAP checks NOx sensor logic, SCR/AdBlue dependencies where fitted, related diagnostics and checksum handling from the uploaded file.

File notes for NOX OFF

Use must be limited to motorsport, off-road, export, test or other applications where the requested change is legally permitted.
