A'PEXi Turbo Timer
This turbo timer allows you to set a predefined amount of time (between 10 seconds and 10 minutes) for the engine to continue running after the key is removed from the ignition. The purpose is to allow the oil to continue to circulate and "cool" down while the turbos also "cool" down. Doing so can help prolong the life of the turbos. The e-brake is part of this system - the turbo timer will only work if the e-brake is engaged. This makes for an easy way to determine if you want the turbo timer to operate each time you turn off the car.
