I'm here new, too, and I want to help you :D. I had the problem too that you described. You must hold the Tab Button so that the engine does not go off when you don't step on the gas. Tab = clutch.
Thanks for your reply! I knew that already. But im using a steeringwheel shifter. So, i want to know if its possible to simulate the TAB button in a H-Shifter.
But i really appreciate your help!
