Im also interested to hear if the script can be altered to make vehicles less prone to stall. I know i tried to tweak the script for a 4x4 truck and when i start the engine in neutral, it will stall every time when shifting to the first gear. So i ended up pretty much having to start the engine in first gear and only then, will it shift up without stalling. So if there was a way to tweak the stalling threshold, it would be nice to hear about it.
