When logging my truck over the last year or two, I noticed that I was never crossing 130mm^3 cmd on the WOT pulls. I didn't give it much thought since i was trying to iron out some other things, but then I found a thread on EFI Live last night that was requesting information of fueling status codes.
As it turns out, my OS doesn't like how quickly I am telling the engine to accelerate, so it switches from code 7 (normal operation)
to code 45
I was being old and fell asleep while i was searching for entry conditions that make the system switch status codes.
Something I am curious about is, I know that the file I'm currently using is not the one that I created originally as James that was helping me tune already had a tune that worked with the injectors that I purchased.
I will eventually hunt down what the OS is looking for and try to minimize it. The first thing that caught my eye was that it set when boost passed 70kPa but thats a very low number that would happen routinely during stock operation.
My next thought is RPM rate of increase.
Maybe someone has sorted this or just jumped OS and ignored the issue?
Image showing the status change, Also, something caused it to drop out of inhibit and go right back.
Here is the cummins status code document that was found on EFI Live
