Default 11.7 A/F at WOT

What could be causing this? I thought turning the COT funtion to false would fix this but its still there. Whats going on?

Just so you know I'm seeing this A/F ratio reading in EFIlive and autotap and not on a wideband.

There is your problem....thats probably the a/f the computer is asking for. You need a wideband to know for sure

Thanks cablebandit. I'll get a wideband next spring after my new clutch goes in. I'll want new dyno numbers at that time anyways.

If your computer thinks it wants 11.7:1 then you should check for positive LTrims in PE mode.

Positive Ltrims huh? How about 20 for postive? What the heck do I do about that. Noticed it last time I was logging. Isnt it supposed to be 0 to -5 ? Or am I looking at the wrong thing? LTFTs or something...? I'm still attempting to learn these parts. Please explain if possible, I'd appreciate learning something new.

if your ltrims are positive at WOT, then you need to richin up your Ltrims. and if yoru ltrims are at 20 at WOT, then you need to richin it up ALOT!

richin up your ltrims about 10% and then see what changes you get from there and make changes as you go,, put your 02's at 0 until you get 0 lrims at wot

How do I put my O2s at zero and how do I richen up my Ltrims? Multiply some table by 1.10 I'm guessing. I'm 1slowcamaro by the way. Sorry to be confusing.
