If you upgrade the M3 to the XZT is it then adjustable on the fly with the commander or do you have to download the mileage or the 70hp specifically and not switch without reloading?

 

With the XZT+ you can adjust it with the commander. You just get the top 3 settings. You'll have to download the mileage program on to the XZT+ when you get it. But like my X2, since I want to use the MMM setting, I have to us the pod that it came with to adjust the X2 to the lower settings.

If you have anymore questions, just call Quad. They're great people. The best customer service that I've run into in a very long time.
