Benefits
- Support for catalyst or rear oxygen sensor DTC cases
- Reduced warning lights from supported lambda monitoring
- Useful for modified exhaust applications
- File matched to ECU strategy
O2 / LAMBDA OFF
O2 / LAMBDA OFF service.
Oxygen sensor and lambda diagnostic software support for supported petrol ECU applications.
What this service does
Technical file support for supported ECUs.
O2 / LAMBDA OFF adjusts selected oxygen sensor monitoring and diagnostic logic, usually for modified exhaust or motorsport-use cases.
When it is needed
- Lambda or oxygen sensor DTCs are confirmed
- The exhaust setup has changed or the use case is eligible
- Sensor, wiring and fuel trim issues have been checked
Process
- Review fuel trim and DTC data
- Read original ECU file
- Prepare O2/lambda-related software
- Flash and confirm DTC status
FAQ
Will this fix bad fuel trims?
No. Fuel trim issues must be diagnosed mechanically and electronically.
Is this only for petrol vehicles?
It mainly applies to petrol ECU strategies with oxygen sensor monitoring.
Can front lambda sensors be removed?
Front sensors are often essential for closed-loop control and are not treated like rear monitoring sensors.
