What is V-AFC? In brief, it is an electronic device that allows the driver to alter the VTEC engaging point at various RPM point to suit his driving style & for different driving conditions like a time attack in a race track or street driving.
In addition, the V-AFC II allows the user to alter 12 points with within the RPM range, allows 50% changes in fuel supply manipulation, allows revison of RPM settings at every 100 RPMs, and the option of throttle opening compensation at wide open throttle.
Features
* All functions of the V-AFC II are packaged into a slim body panel.
* Incorporates a large high-tech bright VFD display monitor to display various functions simultaneously. * The control switch adopted for this killer product is a center push & turn button. * Each low cam & high cam manipulation offers 12 setting to provide a total of 24 settings for tuning as compared to the previous model which only offers 8 settings on each cam. This offers the driver a more fine adjustment possibilities. * Applicable to various vehicles, from wagons to sports cars that has a VTEC engine. * It displays real time data on i-VTEC variable valve timing mechanism's cam phase angle. * A revised function of the VTEC load response by providing a faster processing speed. * Prevents the user from making a mistake of programming an operation of 100 RPM setting by incorporating a password system function. * The lead LED illumination whre it indicates that cam operation is shifting to the high camshaft. * The settings & data in the EPROM will be saved & retained even when power from the battery is disconnected. * VTEC change will be not proceed if data from the ECU is not recognized or does not match. This is a safety function. * The supplier mounting offers various mounting locations without having to follow factory equipment. * VTEC conversion changable point will be different depending on car model. Refer below chart for recommendations. The VTEC changable point can be set to per 100 RPM.
VTEC change point setting mode: * Low cam changes to high cam at 5000 RPM * High cam changes to low cam at 4500 RPM.
Monitor display with 4 channel numerical mode: * Battery voltage read out of 13.3 Volts * VTEC solenoid signal turned OFF from the ECU. * RPM read out is at 6419 RPM. * Air correction factor read out is at 0%.
Monitor display with 2 channel analog mode: * Cam advance angle of VTC. * The V-AFC II shows the VTEC solenoid signal. VTEC change point setting mode: * Low cam changes to high cam at 5000 RPM * High cam changes to low cam at 4500 RPM.
