I'm really not a fan of emulators and EEPROM chips like hondata uses. If you're going to drop the cash, go with something more complete, like the AEM EMS, which has more adjustibility than you'll probably ever tap into, and doesn't require anything more than a laptop and interface cable. You can't say the same for hondata. Not to mention the EMS is designed to plug into your car without ghettofabulous back-date conversion harnesses.
