So..I got my XZT + Unit..got it in...no instructions on which way the switch goes for what setting...it is kinda important to know which posistion is which on a switch with three settings I would think...anyone have a clue?

Here is what Quad said:

Quads post tells the center is timing and fuel only..but withich position is the =45 and the =70 that the paper claims....they need to send a switch position label of let you know by the wire color or something...surely its not just an off off thing..it isa supposed to have 3 settings...I am needing a specific switch direction...

i had the same question and called quadzilla. middle is timing, and up towards the green wire is timing/fuel. the other position is off.

The notch in the switch housing where the nut goes on is "off". The middle is "timing only" and away from the notch is "timing & fuel".

Yep. Mine the same as ^^^^^^

Thanks for all the rplys guys..a huge help..going to try it after work...anyone know whaty the color of the wire is when it is timing and fuel? just want to be sure. thanks again

Even with the unit "off" does it still keep it from defueling? My truck was switched to the side with the notch...the toggle pointing towards the nut...i put it all the way the opposite way of the nut.

I don't think the XZT+ does any de-fueling at all.

Watch your pyro. You can easily see when it defuels......temps drop immediately.

JPR Ram

hmmmm. What tells the XZT+ when to de-fuel? The pyro? There is no place to attach a pyro to the XZT+.

Unless, are you also using the Commander? Because with out a Commander, the XZT+ does not hook up to anything but the MAP and Data link.

This is correct!!!If you mean, does it still do boost fooling in the off position?? YES, it does boost fooling in the off position.

Thanks Hink..that what I thought. I switched the truck to timing and fuel..and dam..talk about a serious studder...its 100 times worse than it ever was...not sure why..I am running the hotrod pump tune to...no clue here.
