I’m using a sctx4 as monitor (I know it’s not the best option). Does anyone have a list of what all the different gauges should be reading if the trucks operating like it’s suppose to?

I took this off my excel i made for myself... like everything please verify. But this is what i go by...

ICP voltagekoeo - .2 is what you need .18 / .28 (before start to show that other levels, if hpop high koeo -> ICP bad
ICP pressure (HPOP#)500psi to start650psi2,500 rpms, 1400-1500psi4050psi (open throttle), once a month i'm told. Keep turbo from sticking, or 1 a week.
IPR - Duty Cycle (IPR)14%-24%30-ish to high 50-ish.As long as your IPR does not ping 85%, then you are OK, ...normal high is about 60% ish. Ideally you want less than 55% and more than 2500 psi reading taken under sustained full throttle 4-5 seconds. Idle should be 9-13% 5-600 psi. Ideally you want less than 55% and more than 2500 psi reading taken under sustained full throttle 4-5 seconds. Idle should be 9-13% 5-600 psi. HIGH NUMBERS HERE MEANS LEAK OR DYING OIL PUMP!!!!!!! (LEAK = stand pipes, dummy plugs, high pressure oil pump snap to connect fitting.) weak pump will not withstand high pressure. DIESEL RON: how hard the pump works. 15 is fully dumpig, 85 means it cant reach desired pressure.

VGT Duty Cycle (VGT) (turbo venes in %)69-7169-74%40-60%WOT (over 22psi): as low as 38% (commands the PCM is commanding the veins in the turbo to. Never want to see 15 and never want to see 85. If high, turbo is not doing what it needs to, system requesting more (sticking veins). Idle can be 80s.
