need help with wideband think something wrong

[Cool28]

Yes it does

[Cool28]

Hmm now I'm thinking something not right with Maf map. Logged twice for about 30 mins each and each time has me lower low hz and raising high ones.

I'll have to post a log when I get home

[Cool28]

heres my log and my tune. This is a heads and cam ls1.

Maf map uses data from ben from serial WB (factor).

the tune cold starts way lean unless that from pe being turned off for tuning. When warm decal rich(11-1) tip in to throttle lean (15-1). Driving afr look good

Ive tried everything in ve to try to fix decel rich to no end. Also don't know why even after I adjust maf it wants me to adjust it again by the same factor

Your PE is not turned off in this tune... but it is set dangerously lean.

I recommend that you do NOT drive with this tune.

Ah ok I see what u mean the 1.16? Hmm in tuning tips said to set that to 1.16:/. I'll change it back

Yes, set it to 1.16 EQ ratio... you've set it to 1.16 lambda, which is about 17:1 AFR... dangerously lean. Always be sure to check if you're setting a value in EQ or lambda... getting PE wrong like that could cost you an engine.

Big thanks. Afr is right in now on starts. Still have a lean tip in though.

[Cool28]

Hmm just had a thought. Would pe be in control when deceling? Then when I give it off idle it uses ve so I get a lean spike?

+1 what statesman said... set your tunetool units to EQR, restart the tunetool, and redo the PE table.

[joecar]

PE enables when the following are met: B3608, B3609, B3613, B3616.

So the PE table is not active during decel (since B3616 would not met).
