My wife's car runs on LPG which is more resistant to knocking. I'd like to take advantage of this fact and increase low-end torque (city traffic) by advancing ignition timing a bit. Can you please share address of ignition maps for this ECU?

Am I looking at the right location? Not sure - the values seems a bit too high for spark advance...

Mini Cooper EMS2000
Spark advance maps size 12x16, factor 0,375,offset -23,625, 8 bit
Base spark advance map in your sw is on 75EF9 address, Y axis rpm, X axis air amount.It is a Siemens, so axis are not in front of map, there is a axis maps area at begin of dump

Thank you Adrian! Now the values make much more sense. I really appreciate it.

Would you be so kind and explain what are factor and offset? Does factor=0,375 and offset=-23,625 apply to all maps in Siemens?

Finally, any suggestion when it comes to advancing the ignition?

Only for spark advance maps.

I'm going to start with the following delta. I could double or even triple the increase but the car needs to run on petrol too. Any thoughts?

You have to define the map axis.Whithout axis, how do you know to change map values????You practically drive a car without a steering wheel.

As you explained earlier: X axis is engine load, Y axis is engine RPM. Ignition timing always advances with RPM and retards with the load. With that said, by just looking at the values, I'm advancing ignition for low/mid RPM and low/mid load. Please correct me if I'm wrong.

I'm wondering about these negative values in the upper right corner. Are you sure factor/offset is correct? Would that mean ignition is retarded past TDC under WOT and low RPM?

Yes.
