“If you turn 15-degrees, you’re going to hit the wall pretty quick,” Davis explains. “But if you’re on the interstate and you barely turn your wheel you’re eventually going to run out of your lane. Well we know the velocity, we know the feet traveled, we know what a 3-degree deviation is going to do, so then you can fairly easily calculate that in 90-feet of travel the car is going to move 10-feet sideways and there’s a wall there. So then it’s up to the user to set up how much lateral deviation to allow from the starting point,” Davis explains.


To combat user error where turns through the pits or staging lanes could potentially kill the ignition or release the parachutes, one can either disarm the VPS until staging, or program the ECU to only enact the do-if actions once driveshaft speed is above a certain parameter, so the actions won’t occur until the car is under power on the track.
