Injector duty cyle at idle is at 3% .. this was both with my stock ECU and now using my wolf3d .. .
Pulsewidth wise, I'm running about 2.5ms depending on electrical load at idle..

it might help if we add what size injectors we are running and what our idle RPM is

i'm running 550 primaries and my idle is approx 1060rpm

Typically about 4% - anything under 3% is pretty unstable.
