I'm getting random missfiring when I lean more, and it gets a lot more unstable (probably due to missfiring but not as much to be noticeable enough expect as loss of power).
Lambda=1.25 +/-0,05, what I'm running, and low load (100km/h 130..150mg/s) about lambda=1.10-1.15 since it didn't seem to have any negative effects compared to lambda=1.05.
I did drive most of the time with stock vanos maps, before doing anything for them. Only ignition and fuel maps modified for lean burn.
What I'm most interested, is how it works at 100km/h since it seems to be more difficult.
Load is 165-225mg/s and 2500-3000rpm maps are most commonly used cells at 100km/h
Sometimes 130-150mg/s, but usually not possible to keep the speed around there.
Exhaust advanced to 105 has been so far most stable at low loads (<150mg/s) at higher speeds, so that's why I set it up to 105 at low load.
