Apexi V-AFC II

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.

Settings:
* High rotary : 3,000 - 7,000 RPM
* Medium rotary : 3,000 - 6,000 RPM
* Low rotary : 2,000 - 6,000 RPM
