I was wondering wats the difference between different chips for your ecu? I did a search and all i found was p30 this, p72 that, but wat the hell does that mean? I have a GSR swap and i was looking into ecu's to get but i dont want to mess up my engine. So what it all comes down to is, what chip/ecu should i get to keep my rev limiter and get ried of my govener? And also wats the difference of a Hondata and a normal Ecu? Sorry if these are newbie questions but i just dont get it. And never hurts to ask.
