Lambda
Sensor 3 & 4 Pin Sure Seal Wiring Instructions
Important Note:
If there is not a lambda sensor currently fitted or you wish to use a wide band lambda controller, your MBE ECU Lambda details will be disabled, therefore the MBE ECU will have to be returned to SBD Motorsport for calibration. The cost will depend on the ECU model & under certain conditions the car may be required for emission control calibration. Contact us for details.
