AFR at WOT
Those of you with tuned cars or canned tunes with wide bands, how consistent is your afr at wide open throttle? I need to know as I evaluate my tune.
Thanks!
Thanks!

Ugh, yep. Mine is screwed guys, it pulls in getting rich, say from 14-13-12-11.8.9.8.6.8.4.2 (then it leans out, this is @ 5k-5500) 12.1.2-11.9.9(@ about 6k is comes back down)11.2-10.8.5.2
If you can read than in a way that makes sense (xx is the point and .x is in the same point but the tenth) , thats what it looks like. Dang. I'm upset about it too. It is all over the place, roughly the same everytime. What do I need to make him fix. CHEVYCOBALTSS3 help me out man lol. I know your out there ha ha.

Your AFR at WOT will be whatever you tuner set it for. I borrowed hpt and adjusted the afr. Cause I am a beginner tuner and did it quickly mine goes from 10.8 and steadily rises to 11.4 -.6. Dont quote me on the below. Most afr guages only go as low as 10.0 so if your guage is reading 10 then it could be 8 for all u know.
Tuners have their own preference. Afr could be flat throughout the rpm range, ramp up I.E. 11.2 @ 2k -11.8 at redline, ramp down I.E. 11.8 @ 2k -11.2 at redline, or maybe even a lean-rich-lean or rich-lean-rich combination.
Someone did a comparison or a ramp up and ramp down tune a while back and the dyno runs were negligible at best.
Anything above 12afr especially in the upper rpm range is usually considered aggressive but the afr is just one part of the tune.
Me personally I would tune in the winter and set it a little lean so when summer comes around it will richen up a bit and u dont have to retune to be safe.

when at idle or even partial throttle, it's normal to bounce around but should be around 14-16 consistently, at WOT or full boost it should be between 11-12 on the AFR gauge. <-- that is the one that matters most. if you're tune or canned tune isn't presenting these numbers during the high boost conditions... then there's something wrong
