    the famous VTEC light

    Just want to know if anyone has done this. For those who don't know what it is. It's a light that comes on when vtec is engaged. I'm curious about this and want to try it. Can anyone give me some tips on how to do this? Will it work with our vtec system?

    Sounds like you are looking for a shift light. You can set them to any pre set RPM. There are many kinds available. I like the one from Pivot.

    I'm not looking for a shift light. I actually have the one by pivot.

    I know what you are talking about. It's a light that comes on when V-tec engauges. I saw them all over ebay a while back. It's acully a dash kit and looks like one of the warning lights inside of the dash. It says v-tec on it. You know how we have an engine light in our dash. Well its the same thing but says v-tec on it.

    Yeah that's what I'm saying. As far as I know, It's only requires an LED wired to the Vtec Solenoid but I don't know where I can find that or how to tap it in.

    lol then what would I use for a shift light if I want it to go off at 6.7 k.

    Here's what I want to do. I just got myself a takara choro q CTR. I wired an LED into the Headlights and just for fun, I want it to light up when the Vtec kicks in.

    I-Vtec Threshold at 2800

    Here's the straight poop on our I-Vtec, (as quoted from Sport Compact Car) the rsx's motor has true intake variable cam timing and lift. at ~6000 rpm, the lifters stop following the wussy little lobes that they follow at low rpm's that gives the motor good gas mileage, then engages big old honkin cam lobes, and varies the intake and exhaust timing accordingly. Our motor (the K20C) has something similar, also called I-Vtec. The motor follows the wussy little cam lobes at speeds below 2800 rpm for good gas mileage. Then at 2800+ the motor engages a little bit more agressive cam lobes on only the intake side, and varies the timing accordingly. That's it, no big high end, (although it still is very good for a 2 liter) but helps get good gas mileage as well as low rpm torque while not sacrificingtoomuch high rpm horsepower.:'( :o

    As you all may have noticed there is a surge in engine power
    near 4800 rpm. Whether this is vtec or not, i think this is the
    sweetest spot on our rides right now. I have only seen articles and
    feedback on what the base RSX engine i-vtec specs are.
    (very diff. intake with smaller dual runners)
    I am still waiting for a good explanation of
    what ever is happening at 4800 rpm. When Hondata gets finished
    building the chip mods to the Si(R) then hopefully we will have
    a better understanding of what is going on at 4800 or there abouts.
    (I'm hoping this IS i-vtec large lifters and not just cam overlap)

    I have one in my ep. It is not what I had expect it to be. The LED comes on @ 2200rpm, which due to the VCT.

    Take a look at this thread maybe this will help?

    But the article is refering to the Element, but I think it is close enough technology.
