The CAMCON-HI allows you to take unrestricted control of your VTEC & I-VTEC's valve timing into your own hands. Along with this, the ability to control your A/F will allow you to more efficiently and precisely tune your vehicle giving you a higher level of performance and fuel economy.

Honda/Acura VTEC & i-VTEC

The CAMCON-H controls the VTEC & I-VTEC's V-tec points and Valve timing of +/- 20 degree in 15 different points of 500rpm increments within 2000rpm to 9000rpm Range.

A/F is controlled -10% to +20% in 17 different points of 500 rpm increments within the range of 1000rpm to 9000rpm.

VTEC (standing for Variable valve Timing and Electronic lift Control) is a system developed by HONDA to improve the combustion efficiency throughout the low to high RPM range. This was the first system of its kind in the world invented by Honda's chief engine designer Kenichi Nagahiro and eventually led to different types of variable valve timing and lift control systems that were later designed by other manufacturers VVTi & VVTLi from Toyota, AVCS fron Subaru and Vario Cam Plus from Porsche. For the K-Series motors there are two different types of i-VTEC systems implemented. The first is for the performance motors like in the RSX Type S or the TSX and the other is for economy motors found in the CR-V or Accord. The performance i-VTEC system is basically the same as the DOHC VTEC system of the B16A's, both intake and exhaust have 3 cam lobes per cylinder. However the valvetrain has the added benefit of roller rockers and continuously variable intake cam timing.

i-VTEC (The i stands for intelligent) 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.). 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 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 rpm. The effect is further optimization of torque output, especially at low and midrange RPM.
