Let's get some more info on this?
well I don't have much to report,
I had this issue with my scan gauge and now with this piece. It shuts off after about 4-5 minutes............. but if you shut off the truck and restart it stays on, so it must be tied to the odb2 port somehow, but my snap on scanner never turns off when plugged to it.
Other than that, it has a lot of options, different parameter set ups, and I just ordered a mount that should work with it mounted to my gauge pod cluster.
the only other issue that I have is that the cord should be longer from the odb2 port, it works well enough, but if it was about a foot longer, I could run it along the bottom of the dash, up the driver pillar, and mount it with the suction cup mount above the rear view mirror.
