Bmw 1m mhd ots tune

[nick_r]

I flashed my bmw with the mhd stg2+ ron95 tune.
Bmw 1m, 22.000km, intercooler,exhaust,downpipes and charge pipe.
I have timing corrections in combination with throttle corrections just after i hit the pedal to start a log or after a shift..
Always use ron 98 fuel.
I tryed ron 100 fuel and installed new ngk spark plugs, no solution.
Is it possible that i have timing corrections because the overboost?

Timing corrections can be seen on a simulated stock tune also, especially part throttle.

I found no difference using stage 1 or stage 2 cobb maps, and was also running better fuel than the map called for. I eventually went with a custom tune, and even with that there are occasionally timing corrections which I have been reassured are a normal part of the DME's elaborate timing control.
