I know one of the user adjustable settings with the XCal2 is axle ratio. What I am trying to find out is;

Is the axle ratio setting changable on multiple cars, such as reading error codes, or, is this one of the settings, such as the tune, that is only adjustable on the car the XCal is "married" to?

If only usable on the vehicle the tuner is "married" to, what would the process be to uncouple the XCal from the original car, use it on the second car to adjust the axle ratio, then return to the original car, or is this even possible? Would it matter if the original car is a GT, and the secondary car is a 6 banger?

Thanks in advance,
Mike

 

I'm pretty sure it's for the car it's "married" to. Reason is the adjustment is made to the .ll3 file in the tuner and then you have to upoad it to the car. Unlike codes that it only reads it from the PCM and can be done in a different car.

 

I'm pretty sure the axle-ratio adjustment is married to the car, as I believe it's one of the "optional parameters" of the tunes. Since the tunes are tied to the car, so would be those options.
