who programmed these? and whats different. the main reason you get a new ecu programmed for you is for YOUR specific mods. 250 for a "universal style" "programmed" ecu is way too much. when you can send it in to hondata and have it programmed to your needs to match your car for optimal gains. (given it may be just a bit more, i think 250 is for a base price) either way.

because hondas run on MAP sensors. when you upgrade something, such as an intake, your engine doesnt know any better. it wont have its biggest gains it can have. thats why having a prepgrammed ecu like that isnt going to help. because it has to be changed after. okay i think i wrote all that right. might be a bit confusing. oh well.
