I've been running the Quad mileage max module (with great results) and now I've upgraded it to an XZT. My mileage went from 17mpg stop and go to 11mpg.(Even if I behave myself.) My question is, Can I program this thing back and forth between the 2 : MMM and XZT? I would like to run the MMM most of the time and program the XZT for when I want to play or haul a heavy load. Thoughts or comments??

 

Do you have 3 settings on theXZT box? If so I think you can download (I am guessing it is the new box) a mileage tune that eliminates the first setting and makes it the Mileage tune. The other 2 settings are as when new. Should be originally 25hp/45hp/65hp. With the new upload its Mileage/45hp/65hp. Look on Quads web site for the tunes available for your box. When I first bought the XZT box on my 04 truck I quickly saw a 1-2 mpg increase with it as long as I kept my foot out of the throttle. With my Std X2 Quad box same thing, keep foot out of it and mileage is good, heavy footed numbers go down quickly.

 

I know I was able to run through the 3 settings on my XZT with the Commander hooked to it. Do you have a Commander?

 

You can do this by going to www.quadzillapower.com and download the update for the Max Mileage Tune. There are two different ways. If you are using the Commander, the update will turn setting #1 into the Max Mileage Tune and the other settings will stay the same. If you don't have the Commander, you can still do an update and turn the whole box back to the Max Mileage Tune, but you wont be able to change settings. You will have to do another update and go back to the XZT. The updates take only a minute to do.

To clarify a couple of things, my module originally was a MMM only. I have no commander. I tried to go back to the MMM software and it won't let me. I keep getting messages saying invalid module in the update box then I get an error message from the computer. I'll call Quad tommorrow and ask them. I want my mileage back!! I've run several days now normal driving and I can get no better than 14mpg. I can almost see the fuel guage moving. My MMM really did help a lot, in hind sight. Thanks for your input.
