I know that if that valve moves any one bit while you are driving (popping the clutch with the system off) than it turns the system off until you turn off the car and turn it back on. this has only happened to me twice and i pop the clutch every so often to race, i mean get ahead of someone.
i wonder though, if i did wiggle the asc valve while the motor is running, if it would disable the speed limiter??? i think it uses the same valve to limit the top speed because the ignition is not cut when you get to 120. instead the car will just hover there indefinitely w/o gaining or losing speed. any incite?
