there is a mod for the jdm but the time messing with it, and the freeware software to work with it and adding configs for unsupported chips etc. you would be MUCH happier paying the 40 bucks for a PicKit2. seriously i have spent way too much time screwing about with mine to get it to be able to program a 16c717 and 18f4553 i'm buying one myself after christmas.
