ECU Tuning & Fuel Management - vtec engage?

i have a 02 civic si andi recently put a vtec light in and it seems that mine turns on at 2250 rpm wich seems really low does anyone know if thats right?

Thats way off. The VTEC should engage at about 5100 rpm.

hmm thats what i thought...its consistant in every gear i wonder ifi got the right wire...

what did you hook the vtec light into?

A newbie question. I kind of have an idea about what VTEC is but I'm not so sure. Most likely I assume that my civic doesn't have VTEC or I'd have more knowledge about it. Does it give the engine more power? If so would I be able to get VTEC on my ride, is it something you can install? How much would it be? My civic is a 2003 LX model.

If your civic has the stock motor in it then no, it does not have vtec. Do a search for vtec on this forum to find the video that exlpains how vtec works. I could explain it to you but pictures or video in this case speak a thousand words. As far as adding it to your car I'm not sure. 6th gen civics like mine you can do mini me swaps (add vtec head) but I have never heard of doing one on your car. To swap to a D17 vtec engine from an EX civic would probably cost around 2k but I am not sure. Do some research on hear, you will find some good stuff.;)
