My mk1 172 is about to have its decat from ktec racing fitted. My car has two lambda sensors, the janspeed has one hole. Can i still fit it??!!!!! its only the return sensor?!
No problem jsut unplug the second sensor and cover the wires and tape them up away you don't need the second secone hence why there no hole the emmsiosn light only comes on if it detects via the sencond sensor that the emmsiosns values arn't right however if it detects no signal ie the sensors disconnected nothing happens
