I'm finishing my Megasquirt install into my M104 190E and it's time for me to start looking for basemaps.

Does anyone have the factory ignition curves/maps for the 3.0 or 3.2L m104's? If you have the fuel maps/curves too that would be lovely.

Thanks

I do not have any maps but the max timing is around 18 degrees and the max injection duration is 18-19ms. The stock injectors are around 19-20lbs if I remember. Around 10-12 degrees of timing at idle. I run around 28-30 at light load cruise and scale down from there. The cam should come on around 2000rpm and cut off at 4800rpm.

I haven't been able to find the ignition curve for the m104 980 engine but what little info I found is the following :
- ignition advance without vacuume : 21-25 @ 3200 rpm
- ignition advance with vacuume : 34-38 @ 3200 rpm

Here is the timing map I'm currently using it's street tuned to 0.6 bar (160kpa), my car runs great with it .



P.S. My timing at idle is 8 degrees, I use the "Idle advance setting" in megasquirt
