Cranking rpms are normal. Just as fast as my lml. Didn’t try unplugging the regulator but it is looking for 43mpa at idle and getting it once it’s running. I don’t recall what the mA was at.

oh thats terrible. healthy main injection rate is 8-10mm3. This is why your balance rates are going to 0 because the main injection rate is probably falling to damn near 0 or 0 which is the injectors just completely shutting off. You can get a lope from this too.
This could mean shot injectors or the tune has been dicked with in the 0-10mm3 area. you can bandaid it by cutting pulse width down in that area and may help teh starting issue
I kind of thought so but not sure.
That was main inj fuel flow rate on the pid.
It’s at about 4 in drive.
return rates wont tell you what the main injection rate is telling you. the injectors are letting too much fuel in the cyl. The computer notices this and stars pulling pulse width back on the injectors. they can only go as far as 0 unless you scale down the table in the idle area or put injectors in that are not leaking. You just happen to have injectors who have all worn out evenly. Being they are most like VOC injectors, this does not surprise me a bit.
the hard starting is probably from the fact the injectors are on the cusp of returning too much fuel and the fact the tips are leaking. crack an injection line just a bit loose on a known good running truck and it will do what your rig is doing. Like Corbin is saying, all signs say "injectors"

Why no haze at all if they are hucking too much fuel into the cylinders? Nothing even on startup. And I mean nothing. No codes either. Wouldn’t you get something if it had to pull that much fuel? Just trying to understand what’s happening.
because all 8 injectors have worn evenly and the computer can still account for too much fuel in each cyl. it reduces pulse width and you dont get a haze. You would never get a code cause there is no reason to throw one (dont believe there is a OBD2 code this type situation to begin with in a diesel). you dont have some injectors that are flowing the correct amount and some that are not, that is MUCH harder for the computer to even out and as the varience grows, hazing starts and increase.
Ok
Well trying to load a file in to my v2 to log this calc frp flow via bbx but every time i go to program it I get error code for a write failure. Starting to get pissed off at this whole efilive thing. Not sure why they had to complicate it with this v8 bs. 7.5 worked fine.
