If your idle is fluctuating in open loop, no worries. Closed loop idle should be steady.

You sound like you know you’re stuff
Maybe you could tell me why my 6th gear makes a noise and higher gears at cruising under minimal pedal application (just flowing along) one of those higher shifts tends to be very…slow to engage. Actually experience a quick jump of 50-100 rpm right before the drop in RPMs and a hard shift.. I’ve never experienced this small stutter or catch in the gears before.. doesn’t happen in manual paddle shifting. Doesn’t happen under WOT. This is also not the known 3-4 hard shift have been able to verify. Sorry to thread hijack
