the famous VTEC light

[myeverlovinsir]

I wish I could believe that there were some explanation here.
My dilema is still there, after reading the thread on the ELEMENT
(5 times) and following every other available link on that site.
I am still puzzled as to what is happening with our rides, I
know some have responded with the same feelings, just don't
want to label or prejudge what is going on at 4800 rpm (and above).

I will be patient and hope my hondata dealer will have more
on this next week.

btw: thanks for providing the link SLOlife.

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

...? Our Si have valve control only at our intake valve, while the RSX have it on their intake and exhuast valve.
