The highly anticipated release of the new A'PEX VAFC II started a new revolution in piggy-back style fuel controllers. Building upon the world wide success of the previous VAFC, the new VAFC II has taken the proven technology of the last VAFC to the next level. For optimal fuel control, the VAFC now allows for 12 point fuel manipulation in 100 RPM increments. The VAFC II also allows for the VTEC engagement point to be manipulated from 3000-7000 RPM, including the new i-VTEC systems. The redesigned case features a center push button with a rotating outer switch for easy and precise data input. To protect data maps from being tampered with, the new VAFC II features a password protection system.
