Im trying to tune my e39 528i with MS41 ECU.
I tried to set ignition timing to 4 degrees earlier, but it's no use, the car runs worse, with higher consupmtion.
But there was no detonation and i run on only RON 98 gasoline.
What i have to change, so the car would be a little more economical and to improve engine smoothness in idle.
Reduce injection duration and advance ignition?
Or what else?
I would be very thankful for some advices.
I'll add the ori file and my unsuccessful mod file:
