Hi,
maybe a quick question, but maybe i've overlooked something. Can someone explain me why the CL Idle is disabled at 5.906sec and 12.703sec.?!?
Thanks

Hi,
nobody an idea why CL idle is disables in the measurement?
Took a look in the code and did not find any clue.
Maybe some rpmdot spike in between the two measurement points?!?

Re: Why CL Idle is disabled?
Do you have a nice OL idle yet? My perception is that it is difficult to tune CL until the OL is very good.

Re: Why CL Idle is disabled?
OL idle is fine and until a few day's i did not had the CL Idle disable issue.
Maybe PID Parameters and Pre control idle duty is a bit off due to some throttle adjustments some time ago, but as saied, it did not made any problems until today with the same settings.
What is a bit strange, that i don't understand the reason for the status2 to go from 128 (CL Idle on) to 0 (CL Idle off)... i can't see any threshold (most likely rpmdot because throttle is closed) triggered in the measurement, but still status2 changes to CL idle off state.
Just want to understand what caused the CL disableing.

Re: Why CL Idle is disabled?
I don't see where CL idle is disabled in the log, duty cycle never goes below 36.5.
I do see a lot of oscillation even when the duty cycle is unchanged, this should not be happening.
I would suggest turning off CL idle and try warm up only and see what kind of idle you have.
If is is not stable you need to get a stable idle before trying CL idle.
I also noticed when it is oscillating afr swings from 13.803 to 15.993, this needs to be addressed.

EDIT: I would turn off ego correction at idle and adaptive idle for now also

Re: Why CL Idle is disabled?
Hi,
idle duty is not 0% this is true, i guess the engine speed increase comes from deactivating of idle advance function, not the idle air supply.
Please watch status2.bit7 (128dec) there you can see the toggeling of CL Idle.
again, i can finetune everything, but i would like to understand which parameter caused the toggeling, because i assume it should not have happened with the calibration. Independently of the fact that there might be some finetuning necessary.
