I have a question concerning OBD2 cars, specifically ones using the Cobb Accessport and 5mt. The Accessport is able to display what gear the car is traveling in. Since the transmission does not have a gear selection sensor, I would like to know how the ECU is determining the gear.
My theory is that it is a function of vehicle speed sensor input and RPM. Can anyone shed some light on this?
