Since you have WB's what is your AFR at 840 and your friends at 860?

Oh sorry, thats about 11.8-12:1 AFR for the both of us. I meant to post that ><

Also- not saying you should run that, just saying NB o2's are next to worthless.

Ah ok. Yes your example and mine of 910 -920 being 11.6, shows the unreliablility of NB readings.
