Is it possible to disable closed loop lamdba at idle only?

I have nice stable and very close to stoichiometric idle with CCL enabled (wideband). However, I'd like to run it leaner (e.g. 15-16 AFR) at idle and possibly cruise in order to improve my city cycle mileage. I get pretty nice results if I disable CCL globally or if set correction amount to zero. Unfortunately I can hardly stabilize it if I enable CCL and target lean AFR, especially after a blip.

Thanks!

Head to the Closed loop lambda area in Scal under Run mode fueling - Corrections

Then select Wideband lambda sensors

Expect you are using base target 1.

All you need to do is in the idle cells is instead of input a target AFR just input 0

Done

Thanks a lot!
