Head #7? Head #8? I don't know. Tested the injectors, and #6 failed the return flow test. Replaced #6 Injector, and saw that the cam was flaking as well, so did that (22000 hours on it). Plugged in insite, it ran fine empty pulling hills. Some information:

1. Fuel pressure commanded would come down when coming out of a pull empty, but fuel pressure measured would keep climbing up.
2. After injector replaced, above was not happening. Climbing a hill pulling about 53,000 kgs, fuel pressure measured and commanded looked like below.
3. Now another day of work, no insite plugged in, and it has started pissing out fuel from the same point on the head again.

Orange is commanded, grey is measured, blue is RPM.


What am I missing?

How do u get to that screen on insite ?

I took the data output from a data log, and then plotted it in excel using a pivot chart and filtered it for %load so I could get to the hard pull. Sorry if my post implied that was insite.
