I like the idea, but I see some problems.
First, I'm not going to buy it before I test it out. I need to be able to DL a trial before I have to fork over the $49 for the whole thing.
Second, $49 is just high enough that I'm having seconds thoughts about whether I really need this. A few bucks cheaper and I would be happy to pay you right now.
Third, there are no instructions anywhere as to what I need to do. I DL'd the file, tested out INPA just to make sure that all was good, the opened up your program, and I couldn't get it to connect. I'm guessing that it was because I hadn't paid you yet, but I'm not sure. It wouldn't respond to anything I did. Maybe some status lights to tell me that I'm connected to the car or just something.
