Ive been looking for a while now for piggyback ecu's and im very interested in the greddy e-manage ultimate. my question is however, is this compatable on my 2004 spec v, if it is thatd be awesome and can anyone give me tips on installing it, but if its not does anyone have good recommendations for a system that can adjust spark timing a/f ratio and so on.

thanks
