[Bitchin' Camaro]

No matter the setting, the car always starts with the valves open (bark). And you can't adjust the setting prior to start up anyway. Stealth mode (which is actually the Snow/Ice mode where the valves always stay closed) cannot be set as a default on start up, only Tour or Sport. The difference between these is only at what rpm/throttle % the valves open. Track mode keeps the valves open all the time (but has to be manually selected after start up). So for example, on start up in Tour, the valves are open, then close after about 3-4 seconds. Same in Sport. It won't start in neither Snow/Ice nor Track. If shut off in one of those, it will restart in Tour.
