Oh ok, thanks matt,

When my engine is warm enough (70°C), the car was leaning itself so i added a bit of k (+/- 48 000).

It's running great now, except my Knock fuel map is highlighted in green as well with the normal Fuel map. Why ?

At low RPM (825/850) my timing keep bouncing around 5 to 15 deg.

To be clear i don't intend to perform the tuning by myself, but i wan to see if there is a stupid mistake before i get the car to the dyno. :oops:

Stream mode (logging) doesn't read the knock flag, so we highlight both maps. That is normal behaviour. Tuner mode can differentiate which map is selected

Timing will fluctuate (along with AAC) to keep stable target RPM idle
