Hello everyone,
Just thought I would post this on here because I cannot seem to find out why, at idle, my car's RPM will jump up and down like a nutcase. Basically sounds like it has rotational idle at times but it doesn't.....
Basically, what is happening is that when at idle, I have noticed in the "Monitor" function that the ignition timing will jump around. Say from 20, to 0, to 15, to 2, to 5, to 20 etc. This seems to be what is causing the "hunting" RPM. Even though the settings on the IGN map says to sit at 15 at idle. Most of the time it will sit at 20....or jump around.
What the **** is going on as myself, a local tuner over here as well as another workshop cannot figure out what is wrong.
The car has not had a full tune as of yet, but the maps have just been cleaned up to suit larger nismo injectors as well as 80mm AFMs.
Any help is greatly appreciated!
