I discovered this screen (under main screen/car/sports display) which shows useful information including oil pressure and temperature.
However, even at high revs the oil pressure reading does not indicate more than 10psi.
Anyone else tried this screen and got more accurate results?

That's the boost pressure from the turbocharger :)

Oil pressure would be in the order of 60psi at higher RPM :thumbsup:

Amuses me that halfway round a tight bend they think you may want to be checking the G-force instead of looking where you're going :?

It's confusing on the screen, my first thought was that it is the oil pressure (as indicated by the oil can icon under the temperature scale).

The G29 User Manual refers to it as the 'charging pressure' which is the turbocharger exit air pressure. It's not very clear at all. Same on mine, shoots up to about 0.7 bar during acceleration but around zero at cruise condition.

I’m sure a remap could put that up to around 1.5bar, hardly any boost needed at cruise, unless cruise is into 3 figure speeds :oops:

I wonder if it measures the G-force when you hit a tree? :?
