Air:Fuel Guage

[tinygiants]

I installed an AEM Air:Fuel gauge. It is reading as erradict as heck. Is that normal? At idle is reading anywhere from 14.2 - 15.2. Under acceleration is bounces all over the place.

Engine trouble? Installed wrong? Normal?

Thanks.

14.2-15.2 is normal...don't worry about idle number, worry about WOT a/f.

Sampling rates will fluctuate too much at idle and decel.

-Red

Thanks for the reply. What is an ideal number?

Thanks.

Under acceleration? Do you mean part throttle or WOT? At WOT it should be steady.

lambda .. 14.7:1

Gauge should read (in a perfect world) 14.7 cruising / Idle / Part throttle, but will fluctuate. Computer will aim for the target 14.7 though...

depending on mods (na) 11''s (rich stock) ..Ive seen 12's...

F/I - 11's
