I noticed on my datalogs whenever I get a moderate amount of wheelspin my A/F goes leaner. This is causing me to hit lean cut which is annoying. I understand my lean cut is on the aggressive side. Lean 1 never triggers Lean 2 is the issue my Lean 2 settings are below:
Max A/F: 11.8:1
Load: 14.1 psi
Trigger time: 150 ms
This seems to be an intermittent problem and I'm just wondering if I need to loosen up on my lean cut settings or add more fuel. When the tires are hooked AFR's are right where I want them 11.5-11.0. This issue doesnt come into play until about 6800rpm. There is no VTEC crossover that could be affecting the issue.
Lean during wheelspin?
Re: Lean during wheelspin?
Change the lsettings to a leaner AF ratio and a longer time.

Re: Lean during wheelspin?
Thats what I was thinking but wanted to confirm. Thanks. Still curious though is it normal to see a little leaner A/F when wheel spinning. Its not going extremely lean; for example if the wheels aren't spinning and are under load 11.4 AFR when they start to spin 13.5 AFR.
Re: Lean during wheelspin?
You aren't at full load since the tires are spinning.
