Several days after installing the XZT+ I started to have power lock issues. At first the truck would lock itself with the engine off, then when I raised the electric windows the doors would lock. Finally the locks would continually cycle as if the locking switch was stuck in the locking position. This occurred even with the engine off!
I checked all the switches and wiring and could find nothing wrong. Finally, I unplugged the Quad and the problem stopped.
I've been running the more aggressive tune (XZT+ 2000) Anyone else have similar issues? If so, how did you solve this problem?

 

Try sending Jeremy at Quad an e-mail. He helped me with a different problem, but was extremely helpful. He responds quickly to your e-mails. I am no expert, but did you try a different program on it? Or try reloading the same program?
