I think its 5000 for the dodge cmr software. I think when you buy it, Diablo has a training class to attend I think. Maybe Mike will chime in.
I also was told there's a data bank of many many starter tunes or previous working tunes to chose from to start with.
I haven't kicked the 5 g YET.

I'm open to any of it.
