how do you convert the KPA reading to a PSI reading?? The map is shown in the KPA form and im trying to figure out how to read it as PSI.. Thanks!

To convert kilopascals to pounds per square inch, multiply the kpa value by .14503773773020923

Then the values are wrong on the trinity... When I put the boost gauge around "0", it says ~100Kpa... Could you guys look this up to see? When im crusing on the highway, its around ~65Kpa, and im in vac, deffentily not 9lbs of boost lol..

Thanks

0 Boost is atmospheric pressure, which is 14.7 psi....so, 100kpa x .1450377=14.50377, right about 14.7 psi which is atmospheric...

ahhhhh thanks then.. Forgot about the baro.

So is there a way, using MAP kPa, baro, and whatever other readings, to get a value in psi which is the actual psi being sent into the manifold? Is there another value to log which I am missing? My obd2 aeroforce interceptor scangauge is able to do it.

Is this possibly a dodge related issue showing atmospheric?

Yeah, it is simply the way the factory PID works.

I was logging our Duramax this weekend and it shows actual PSI with 0 being atmospheric.
