Wide Bands Come on In A/F

[mikea074]

I wanted to know what my A/F should be at idle and at WOT
I am using a LM-1 unit with a Tune from James @ RWTD.

I am showing around 14.1 -15.00 at idle

When I mash the gas at WOT I get around 12.4

Please tell me what you guys are seeing on your wide bands.


Thanks

I just did some datalogging with my LM1 last night. At idle I see 14.3-14.5, but from 3000 - 5000 rpms my AFR drops to around 11.35.

Idle doesn't really mean much. The computer is going to keep the car close to stoich, which is 14.7:1. You'll want the car running mid-low 11s at WOT for a safe tune. Many feel that high 11s is also acceptable. I would not run the car with an A/F above 12:1 much above 3500rpm.

I get about the same at idle, but at WOT I am no higher than 11.8:1 ...
