Ignition timing corrections
I am FBO e50 custom tune, wanted to know why I am getting a lot of ignition timing corrections at idle.
https://datazap.me/u/chris1337/e50-custom-tune-idle That's a data log at idle, this has been happening for a while. New: plugs coils valve cover/gasket Wide open throttle is perfect, just idle is rough |

That channel logs actual timing advance not timing corrections (knock).
Timing at idle will bounce around as the car uses various feedback to control idle load. Log "fuel mode" next time and send the logo off to your tuner with a note that you have a rough idle. |

fuel mode seems to be at 2 on idle checked like every box for the logging so you can see everything |
