So I have a 12 Ctsv that is in that has been through 5 different tuners. The question I have is the trans pattern seems to be different, not sure if somebody did a segment swap or not. But Pattern A is Normal, and Pattern B is Trailer. So the question I have is, how do I tell which pattern is which when the Ctsv is in "Drive", "Sport" and "Tap up, Tap Down"? The customer is remote, so is there a way to verify which patterns control Drive, sport and tap up tap down? Never seen "trailer" on a car format yet.
