Look along L17, note it reverses direction from 126 to 124 at N15/16. Based on what I have seen, that's never happens. They always need more fuel at higher rpm, not less

I have done a bit of tuning and if you have a flat AFR say 12:1 then the injector duty cycle will rise from low rpms to the point that you reach peak torque and then drop a bit to redline.

As it doesn't actually reach L17 I don't know how much the PFC blends the map so it may not even matter.

SLVR32GTR: Matt Spry will sort it out no problems. Pmed you.
