Question regarding closed loop

[Todd Beenen]

What are you guys seeing at idle for afr ? On TD’s site it says low 11’s at idle, mines at mid 12’s, just wondering in my sensor is bad, or that’s fine?

That is fine, what you need to monitor is WOT afr and cruise.... Mid 12's at WOT will produce the most safe power...

Roger on that.

soo we had a thread on this last year both myself and Knapp are seeing only in the 11-12's while warming up, after that ours were in the high 13's

Would say normal, don’t worry about idle afr too much if running good. Also the closed loop does not adjust at idle it is speed activated.
