Land Rover LR2 Volumetric Efficiency (VE)
Using an OBD2 reader/logger, it calculated my 2008 LR2's Volumetric Efficiency at 60%. I understand that you like to see values of at least 75 or 80%, so my VE of 60 is low.
Does anyone else have a VE measurement of their LR2 to share?

I assume that you are looking at something like the VE from the Torque App
The calculation is based on how much air enters the engine vs. the theoretical 3.2 liters
To get higher VE you want to be at the Torque peak, which is about 3500 RPMs for a LR2
So if you want to see a higher number then put the transmission in manual mode and drive around and try to keep the revs at 3500 or a bit more
ideally find a long steep hill and foot to the floor at 3500 RPM
Then check the VE
Note: higher VE will make the engine seem very responsive but it will be horrible for fuel economy
Because the LR2 has variable valve lift (Intake) and variable valve timing (intakeand exhaust) the ECU is reducing the VE to get better fuel economy (Edit: Variable timing and lift is on the intake only)
