Hey guys

i was wondering what a good air fuel ratio would read on a wideband. At idle and WOT

I did search online and the links threads didnt work and no one had anything definitive.

thanks

my car is running 10.5 to about high 12 low 13 afr

 

WOT should be mid 11's. Idle and daily driving should be around 14.7

 

You are thinking of a turbo engine but n\a is a bit leaner as mid 11's would be quite rich on a n/a car.

 

OP did say a 1iz, so its safe to assume its boosted.

 

Oops I was thinking 1uzfe for some reason so my bad lol but yea mid 11's is pretty much spot on!
