I would have to say yes to the legality of Hondata systems since "it's within the original ecu casing". However, having experience with other chip/car manufactures, I have a problem with Honda ecu mods from companies that don't give any real results (gains?) other than force induction. For example, if you where dealing with VW and Audi, manufactures give you real numbers (torque/hp?).
