I was looking for something simple to give me couple extra HP in my 1990 Accord LX 5-Speed. I was thinking about digging up an ECU from an EX and puttin it on my LX, will this make any differance? Do I have to have an ECU from another 5 speed, or does it not matter? Can I install it without any modifications? I am told that one from a 92-93 EX will also fit. Any info on this topic will be appreciated!

Thanks!
