: Desired Boost PID question

Truck is an 06 LBZ, os 4138. I'm running the new v7.5.4 build 65 with the latest bootblock 2.05.08 apr 25, and firmware 2.05.18 jun 25. The desired boost pid GM.DESTCBOST only shows kPa (metric) as the units. I would like it to show psi. I noticed some pids can be displayed either way, but for my truck the desired boost is only metric. Is there a way to change this in a config file somewhere?

On the main screen, go to:
EDIT
Configure Display Units
Select "All"
Select Imperial

My tune tool is setup for all imperial units. I'm talking about the desired boost PID in the scantool. I want to log desired boost vs actual boost, but I can only get desired boost to show in kPa and I want it in psi.

You can create a Calculated PID and convert it... Something like this:
# Diesel Calculated Boost
# =============================
*CLC-00-000
kPa -10.0 400.0 .1 "{GM.BOOST2_DMA.kPa}-{SAE.BARO.kPa}"
psi -2.0 100.0 .1 "{GM.BOOST2_DMA.psi}-({SAE.BARO.inHg}*0.4912)"


CALC.BOOST F5F0 CLC-00-000 "psi" Air "Turbo Boost"


There's a PDF in the help on creating calculated PIDs, but I couldn't get it to work by putting them in the file they talked about, I had to put them directly in the sae_generic.txt file for them to show up (I might have missed something)...

Hope this helps,

It works either way. I've had to make a few of those. Fuel pressure in PSI and desired boost and actual boost and a few others.

Ok, I'll make a calc.pid to convert kPa to psi. Thanks guys.
