Look like it still doesn’t work in 4.14.3.
I tried with the AdvancedVehicle template but I’m unable to notice any change I make to the torque curve.
BTW for some reason I’m also unable to use the SetGearUp/SetGearDown functions.
I couldn’t help but notice that this issue is open since 11 sept 2015 (Unreal Engine Issues and Bug Tracker (UE-21014)).
That seems like a very long time and feel a bit confused about it…
