you might as well get a chipped ECU and a ROM burner - you would have more flexibilty and capability than a S100...
S100 = marketing.
Marketing research showed Doug of Hondata that a decent number of people never do any tuning on their own - dealer tuning only, or just run the base tunes. Beyond that, there is a perception at hondata (and based on the kids around here with hondatas, I'd have to agree) that few people know how to tune them right. So few people use their hondata to its fullest potential, so why bother making it tunable at all? Enter: S100... S100 is cheaper, so more ppl who aren't gonna tune can get a hondata because they don't need to drop $$$ for a S200. From a business standpoint, a GREAT decision. From a technical standpoint, leaves something to be desired.
As long as you're happy with what you get, that's what matters.
