If your unfamilier with the whole tuning stuff I would suggest reading some information from Hondata's website- even if you dont go with Hondata for your ECU needs, the site has great basic information. I learned alot about ECU's and tuning from this site. They also have a list of compatible ECU's depending on your car, and for which ECU modification you decide to go with.
