i have a 2005 civic si with header intake and catback exhaust. i know that with those bolt ons ur only gonna get so much gain on a stock ecu. but i was wonderin if i swapped out the stock ecu with one from an rsx if first it would be possible and second if it would give me the added adjustments i needed to get the most performace out of those? see i dont have all the money in the world to blow on a fancy kpro you know? so please any info would be great

no man, an rsx ecu will not just plug in and get you gains.
get a hondata reflash http://www.hondata.com/reflash_civicsi.html if you want to improve your ecu without blowing a grand on kpro

The only way a stock RSX typeS ECU will work in the EP3 is to also drop in the typeS engine and transmission.
