I've re calibrated mine, its running like a bag of pants. Stalled on the way home, engine light on going in. I haven't checked the codes yet.

but being lazy I re calibrated it, tweaked the map quickly before tee. But as title, what am I looking for in the lambda readings to insure its not lean. Guide says it should be a solid 0.8-1 volts iirc, at wot. What's the tolerance, is more or less than that value rich or lean, or doesn't it work like that...?

It's a narrowband sensor, so it will pretty much be 0.8-1v or it'll be way down at 0 - 0.3 v or so.

In reality, it's easiest to identify the lambda traces in the little scrolling graph along the bottom (turn the other traces off) and check that neither of them "dip" down on a full throttle run starting from lowish revs and letting the speed build.

Ok thanks Kev, should be an interesting drive in, in the morning.
