Hi there I have a problem that I have been working for a long time.
The advance of the vehicle at idle is not stable.
Any suggestions?

Re: kpro prb v3 idle ignition jumpy?
The K-series ECU uses ignition controlled idle and it will jump around at idle.

Re: kpro prb v3 idle ignition jumpy?
thanks for your answer
I wanted to consult you because this is strange to me
is everything normal?
afr fluctuate with sudden falls of up to 18 s failure?
Is there a setting I need to check.
I have installed base map again.
close loop or open loop does not matter, it is constantly fluctuating
ignition advance on the road as we have specified in the map
my car k24a2 ekkswap
engine renewed 87.5 mm standart cr piston fitted. this problem started

You will need to post the calibration as well as a datalog made with that calibration showing the issue.

Re: kpro prb v3 idle ignition jumpy?
The o2 sensor is working and the engine is in closed loop but the short term trim is not moving.
Why are errors P1167 and P0134 disabled? Does the short term trim ever move?
A warm idle manifold pressure of 41 kPa is high, especially on a K24. To me this indicates the cam timing is not correct.

-Yes is moving, but the datalog is not noticeable because it is too short.

-Tuner did. I will fix it.
