Is MIVEC oil or mechanical controlled?

Plug and unplug...
So the rev limits to 5k, no problem.
Sure there is no harm to the engine or something?

it does not harm the engine unless over reving it.... but why on earth would you want to take it off anyway?
funny thing is no one has dare mention the way i managed to modify cam timing.... work like a charm but is a suicide for the warranty....

OK how did you manage to modify your cam timing? What improvements does it brings? Sounds risky...

Something weird going on here... I filled up the tank last night, then drove 80.4 miles (back and forth between Anaheim and UCLA). Filled up again when I got home this morning. Pump first shut off at 1.734 gallons, and then I topped it off at 2.134 gallons.
That means 46.4mpg or 37.7mpg... wth... last night I hit mad traffic on the 5N, and when I came back I was going 75-80mph.
Am I missing something here? You can get 40mpg just by disabling MIVEC?
Can someone else try this?

Yeah, PR_MIVEC I would like to know too, what does it actually do to MIVEC?

ok i now realize all you guys are magazine mecanics..... to ask the efects of cam adjustment is like been a catholic and not knowing the pope.....
arithmetic; in short by changing the cam timing (retard, advance/overlap), we tune the overall drivability and performance aspect of the car. even stock engines can benefit by dialing-in cam timing/overlap. these are typical variances in production tolerances that when fine-tuned to your particular engine set-up will easily produce added power. many factory cams, ours includded, operate on the conservative side of performance due to emissions and drivability standards, meaning there's always more power to be gained by learning how-to adjust the intake and exhaust valve timing
and guess what i managed to do this wo/ an aftermarket cam gear....

with DOHC, where one controls the intake and one controls the exhaust, you can control overlap.. but on a SOHC, the cam dictates it.. using cam gears you are just "shifting" the overlap around.. (it stays the same)
