Adjusting Parameters Problem

[blderman]

I have an Intune i1000 and am using it on a 2014 F150 Ecoboost. Whenever I try to adjust any parameters the odometer goes blank and the PCM will not respond. I have to then restore the vehicle and load a tune back on again. The same thing happens when changing from one tune to another, yesterday the pcm actually went blank while I was driving and I had to pull over. I am about ready to sell the Intune but wanted to see if I could get some help first.

the pcm cant go blank while you are driving, what exactly happens here?
