didn't capture duty cycle at the drv very well as i was using my handheld scope, but from what i could see, when the engine revs were dropping the DRv duty cycle would reduce, and then as the revs picked up the duty cycle would increase...
would i be right in saying the ECU appears to be trying to control the fuel pressure via the DRV as it is seeing an issue with the ZME?
