I upgraded today to pro hoping I can see the boost value of my turbo. I can't seem to find any info on how to do this. Help? I can see the boost on other free apps.

Turbo boost not an OBD-II parameter, that is rater "artificial" calculated parameter  Boost = MAP - 1atm
Where MAP is Manifold Absolute Pressure


You could consider using MAP instead of Boost

Thanks!

Hello. I own a Volvo V60 D5 with two turbos. There are two pressure sensors. There is a low pressure turbo and a high pressure turbo. What is the value read by software? That of the low pressure turbo or that of the high pressure turbo? I ask myself the question because the value peaks at 1.5bar whereas it should vary around 1. 8bar. The most surprising thing is that there is no variation once the 1.5 bar reaches.

I think the maximum value of MAP pressure in your APP is 255. Can you change this value and set it to 300? 
So I could measure the 1.8 bar.

Unfortunately the limitation comes from OBD-II standard, that is the maximum reported valule is 255 kPa. 
PID 0B, Intake manifold absolute pressure : OBD-II PIDs

Thanks!
