IVTEC
So, i ve been cruising around the NA forums for a couple weeks now that i have another S to mess with while i build the turbo S. I did a search in the FI forums about this but only a couple threads came up that even mention it https://www.s2ki.com/forums/index.php?showtopic=712492 . I was wondering with d-craft(the maker) saying the gains should be more on a FI car then NA and they are seeing 20-40% gains(if i remember correctly), is anyone thinking about doing this do their FI setup. I was gonna leave my head alone for the build but after seeing this am quit interested especially for what he says the price point will be

It would be interesting to see if it could be done with the F20c and F22c engines. Would the currently available standalone EMS's even be capable of running this on a F20c or F22c engine?
For those that dont know much about it, here is a basic rundown.
iVTEC(intelligent-VTEC)[3] introduced continuously variable camshaft phasing on the intake cam of DOHC VTEC engines. The technology first appeared on Honda's K-series four cylinder engine family in 2001 (2002 in the U.S.). In the United States, Honda first debuted the technology on the 2003 Honda Civic Si EP3 with the economy version.
Valve lift and duration are still limited to distinct low- and high-RPM profiles, but the intake camshaft is now capable of advancing between 25 and 50 degrees (depending upon engine configuration) during operation. Phase changes are implemented by a computer controlled, oil driven adjustable cam gear. Phasing is determined by a combination of engine load and rpm, ranging from fully retarded at idle to somewhat advanced at full throttle and low rpm. The effect is further optimization of torque output, especially at low and midrange RPM.

He's not asking if it can be done, he's asking if anyone is going to try it now that a solution has been developled, lol
