just a thought at the mo, but why cant the "V Tec" be bought into play at lower revs? or can it? where can i find out more?
regards Steve

 

The whole point of VTEC is to enable the engine to run well at low revs while also allowing it to run well at high revs. Without VTEC, the car would run like a horse below 5k and would probably have to tick over at 3k. I believe that the existing VTEC line is set there to allow you to go through all the gears at high revs and never have to drop out of VTEC. i.e. a 9k up change in one gear will not drop the engine revs below the VTEC line.

So, in short, the answer is, no, that would be missing the point Mechanically, I have no idea if it's possible to move the "engage" point, but someone elso may...

 

it is posible to lower the v-tec engage point with a v-tec controller(a search should bring up relavant posts)
but in doing this your basically undoing what honda has set up as the optimum settings for the car/engine.

Ok, you could have VTEC cams in all the time:

That's called a stage 2 racing engine, it won't idle or run below 2,000 RPM, spits unburnt fuel unless revved etc etc.

You get the drift?

 

If it spits flames out of the exhaust, I'm sold. Where do I queue?

 

How do TODA cams fit into this?

Are they simply a more aggressive profile, but with the VTEC still engaging at the same point ?

 

The cams control both duration and the lift but NOT the point at which the profile changes, ie. the vtec changeover point.

So the TODA cams, I believe just give a different profile to the Honda ones, they don't actually change the point at which the profiles are changed over.
