predator sport
I cant look up any other info because it wont talk to my truck or computer now. Getting the "application is missing or corrupt" on the predator and on connection step one where it says to update when having this issue i can click the link all day and nothing happens whether its plugged into the PC or not. I'm using downloader 2.3.1.0. the tuner came with 3 files on it already and when just trying to set it up to my pc it never really worked anyway, but now I want to flash the truck and cant.

were you trying to update it?

you need to select legacy connect on dsdl under options and select the correct COM port that the cable is assigned to then you can reload the update file.

Not home now. But I wanted the towing tune for today. I'm calling you guys at 520 am tomorrow to walk me through it since nothing is working and I can't even begin to know what you're saying.
