So I have been using DHP for some time now and all of a sudden I connected to the car a few weeks ago and went to scan and nothing is there. It's like it reverted to when I first go it and had to set up all of the PID's I wanted to scan. I set it up again, but it won't hold it for some reason and its not monitoring some of the parameters that I have set, they just display 0 in the file and have dashes when I have them set as a gauge.
Anyone know what causes this and how to fix it, other than it's not HPT.....
