I have a MAF based system on a BMW M54B25 6 cylinder.
I am having problems with getting the cranking and cold start ironed out.
Does any one know which point on the main fuel table is used for the first injection and cranking comp?
At what point (rpm or other condition) does it start using other points on the main fuel map? (cranking to post start comp change over)
On the factory ECU it is all in ms injection times, not % like in the M800 I have.
In the factory ECU (MS42) I can get a sharp start(easily under 1 second to running) but with the M800 it takes 2-5 seconds to catch(fully charged Optima D34/78 @15V)
Thanks
