Hi,
Faced a problem with the ignition angle retard. When measuring on dyno everything was fine, the ignition angle differed from the base angle by only 1-2 degrees. But when driving on the road, I noticed that for some reason the ignition angle was off by 8-10 degrees from the baseline.
I noticed that the IAT advance parameter has a value of -12 degrees. The intake temperature is in a good(30-35 Celcius) range and there should be no decrease in ignition angle. I am confused.
Maybe the problem is that I did not increase the virtual torq maps and the diagnostics P0101, P0106, P0121 I left factory.
I'd love some help, guys.
