Hey everyone I was wondering what the pros and cons of each system are and in your opinion which is better for tuner hondas. I just bought an 06 accord coupe, one of the L4's and it has iVTEC. Also Im not very knowledgable, what exactly is the diference between the two systems?

 

google is your friend.

all vtec and ivtec does is allow you to have multiple profiles of your engine:
1. low rpm normal driving
2. high rpm "race mode"

iVTEC does what VTEC wishes it could do. But when it comes down to a full built race car, vtec is a pain in the ***.

 

i-VTEC introduced continuously variable camshaft phasing on the intake cam of DOHC VTEC engines. 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 maximum advance at full throttle and low rpms. The effect is further optimization of torque output, especially at low and midrange RPMs.

 

Hey that's what I was going to say J/K No really that's a good explenation.
