I am having a problem since last Saturday trying to get a new DSP2 tune loaded on my truck.
It started out when I was working on it, and I had the batteries disconnected. I hooked them back up, and the truck would not start "just cranked". I found it had a Vats code, and after trying to flash it "unsuccessfully" it finally started. It runs and switches between the 2 tunes just fine, but when I try and reflash it just says "reflash unsuccessful, try again".
PS: also when I hook the Scan tool up to my truck, it comes up with some crazy vin number, and wants me to enter a vin. I enter my vin, and none of the Pids are valid
