Been trying to log some boost readings with the Torque App. I have a 5.3 with Vortech supercharger, speed density tune, 2 bar map etc. If I log boost, the vacuum is 100% correct but when I go into boost it stops at 0.5 psi. I have also tried logging intake manifold pressure and it maxes out at 105kpa. Is there a special PID I need to install etc? I am running 10lbs of boost according to my boost gauge, I would prefer to be able to log it for some different driving conditions etc. Any help or suggestions would be appreciated.

Do you have MAP selected?

 

I sure do. I havent tried any of the other settings since i dont have a maf etc. I really thought the infake manifold pressure would read correctly and i would just have to convert it, but no such luck. Hopefully someone can figure this out because it is kickin my butt.

 

If you have it tuned with HPT, its not the typical MAP sensor you need to log, its the custom 2 bar map in the PID list.

 

Yes i am tuned with hpt. I dont seem to have the custom PID in my list though. The only 2 i have are boost and intake man pressure.
