the dead time is 12v ~1140, 13v~1060
I would suggest that you need to measure that yourself.
if you wind that right back to zero, and wind back the fueling cells at idle to zero, then it should not be running rich.
Surely if the fuel map is at zero, the car should not be running at all ?
He says he has a pulse width of 0.2ms with the map at zero. Surely that makes no sense ?[/quote]
I am not a tuner...
But it seems like the injection open time is a function of the commanded open time and the dead time.
I think the flow is a function of the voltage, dead time, open time, and fuel pressure.
So if he is running too rich:
Then setting the fuel pressure to sensible levels, and reducing the commanded open time make sense.
If it is still too rich, then I suspect that the dead time might not be optimal.
