I'm new to the honda game, but am I a tech at a ford dealer, is there differences in ecu's as performance, or can someone point me into a direction where I can learn about them, p06,p28,p72, all that is to me right now is a bunch of numbers. Thanks

here's an ecu list and what they're out of.. http://civic-eg.com/viewtopic.php?t=11439


in this case, a P06 runs correct fuel/timing/etc for a D15b7. but any OBD1 ECU can be chipped or have vtec added to it to run whatever motor you want.
