hey guys well as some of you know my engine went out, now the only thing i cna remember while i was logging runs is that i saw the duty cycle of the injectors and it was showing 80 percent but during the run the duty cycle will drop to about 4 % for a split second and hten back up does this happen to anyone else

thanks

Ed

It might have been when you were shifting.

yeah it happens on some PCM's. It happens on mine, but when looking at the A/F's, they dont change. Someone, i believe funks, correct me if im wrong, did some looking up on this and found no negative effects. Sorry to hear about the motor.

My duty cycle drops during logs. It appears to be voltage drop outs from the e-manage firmware because, as stated above, there are no changes in A/F. There would definately be a change in A/F if actual injector cycle drops occured.

The e-manage is more than likely not the problem. Look into your nitrous set-up. For example how much spray, how much boost, A/F on and off spray, ignition advance or retard, RPM's your spraying, throttle switch, etc... Give us more info on your setup.
