Strange LBZ Issue
First off, I have to say I didn't write this file. I don't know who did; the customer gave me this file and said "it's really smoky, hang shifts, here's a datalog."
I really would like to better understand these older trucks - I don't know why the truck is only commanding (maybe better said - is only allowing) 40-50ish mm/3 of fuel in first, second, and third gears. When it gets to the end of third it comes to life and starts commanding near 100mm/3 (which is what the tune file seems to call for).
Can anyone shed some light on what may be causing this issue? All of the limiters seem to be set to allow for more than 50mm/3 - and I am not aware of a limiter that is "by gear." Sensor issue? Supply Pressure issue? I'm stumped on this one.
The truck has a single S472, 100% over injectors, and a 12mm stroker pump...pay no attention to the file names...I don't know why it says 60% overs and 10mm pump in the file name (and I didn't bother renaming it).
TIA for any suggestions/help!
