So over 6000 rpm as i undestand, I raise the numbers of the main map to keep the fuel rich but I reach 100% of duty cycle cause IJPU(usec) was to 12 instead of 22.
I do not know if this was the real duty cycle of injectors(doupt for that) but the prob was that motec believes that was real!

That post makes no sense. Just where are you getting the info from that you are at 100% then ?

The numbers on the main fuel map mean nothing and certainly not duty cycle.. Larger = more fuel, lower = less fuel. It's as simple as that

You can manipulate the IJPU etc to achieve the number 100 meaning 100% duty in some instances, but you simply change the IJPU to either give the main map better resolution, or for it to display a range of numbers you feel happy working with.
Whether that be 0-100, 0-50, 100-200, it really doesnt matter.
