i hope i posted this in the right section - Mods please move if not

i have a 05 duramax diesel but i dont think my issue is diesel related


I have been trying to build a custom dash( A) (B works fine) for a while i can change certain things and had better luck along time ago ...

when i try to add a new gauge no matter what i pick it comes up as RPM
im not even picking RPM i have tried with differnt PID lists...no luck

the gauge i would like to have mostly is actual fuel rail pressure
and dsp5 voltage and well all sorts of different ones i dont need baro
ECT so i thought i would delete them and then add new gauge

ive also tried changing the existing gauge and same thing comes up i pick the one i want and wham theres RPM and it wont change no matter what i pick


the reason i want this Dash A so badly as i recently installed a touchsreen monitor and would like some extra info while driving i do like to review in dash B but that one i have no probloms picking and choosing its seems its just with A

sorry about the long rant just wanted to give as much info as possible
thanks for listening
