Does his VSS (Vehicle Speed Sensor) work? Check Engine Light on in his car?

If the ECU does not think the car is moving then the ecu will stay in launch control mode.

Ecus dont just stick in '2 step', its either a bad VSS connection or in limp mode.

Speed sensor, had this problem on drunkinmaster's car. Frustrating how something simple can be such a headache.
