So this happened to me 2 times (attaching logs and tune) - so basically every 2-3 engine starts / warm ups so far.
Strange thing as the Idle Control Active goes to ZERO for a second or so and then recovers to ACTIVE with no know to me condition.
I have no clue why this is happening.

I will check with afterstart delay set to 0.1 and to 1.
In the meantime same settings and happened again.
Attaching log from start to end.

Well with 0.1 it’s still there. With 1 it seems it’s not (or I did not notice).

This is happening again. Short spike down - idle control not active and bump up - active again.
Only noticed after engine start (No touch on the gas pedal) and going directly to idle control.

Yes, Idle strategy is a little bit too sophisticated than in V2.
Especially if engine setup is crazy, I mean big turbo, big throttle, extremely hot cams - within slight revving up below 2krpm, idle often can stay in armed state instead of delicate descending style(opposite to V2). No matter of ramping or active state delay or any other setting, which seems to be ok. Same in aterstart, if they oscilate even without touching PPS, idle stays in armed state. It would be nice to have a log channel, which parameter of idle active state is not achieved.
