Anybody with a Syvecs able to tell me what their wideband readings are at idle and 2500 rpm so I can see if my Lamda sensor is working?
Idle and 2500rpm should be 14.7AFR or ocscillating from around 14.3 to 14.9 if using 02 feedback.
If they are not then it will fail MOT.

If using a wideband it depends where the probe is and what exhaust is fitted.
If the probe is in the downpipe/header it should read fine. But if you have a dustbin of a tailpipe and the probe is only in the tip of the exhaust then the idle and light cruise readings are worthless.
