Idle Engine-RPM in VehicleMovementComponent

When using the Wheeled Vehicle the Engine returns Rotation of zero when the Vehicle stands. The Physics-Simulation of the Vehicle seems to be passably realistic but the wrong RPM is a big disadvantage. Our game really needs realistic RPM Simulation. Is there any way to do this?

Hi, I wan to know how you work around this problem, could you please to share you solution?
