The new Super AFC-II utilizes a state of the art visual display lighting called Vacuum Fluorescent Display (VFD) to provide bright & clear visual information. A new dot matrix monitor enabled a variety of information to be displayed simultaneously where the driver can check quickly. Information relayed can be either displayed numerically (analog gauge style) or graphically. The body of this new product is slimmer & smaller (H52 mm x W126 mm x D18 mm) than the previous offering. This ergonomically designed body houses only a "center button" which toggles & rotates where it enables the driver to navigate (4-axis toggle: up& down, and left & right) and to select functions of the Super AFC-II. This button also has a feature that enables the driver to fine tune any parameters. All these features in the new model's user interface made it much easier & efficient compared to the older model. SAFC-II has a new knock sensor function which alerts the driver. This ensures that the engine is tuned to perfection at every stage. This function only works on vehicles that have an engine knock sensor. SAFC-II Can save two data settings from data collected with respected to air flow adjust rate, throttle duration, engine RPM, etc. The driver could use these two settings in a variety of driving conditions, be it track, street, or just plain cruising. The driver can set up various warning functions in order to monitor the engine operation. These functions includes incoming air flow rate, suction pipe pressure, engine knock RPM, etc. OTHER Settings & data stored in the new Super AFC-II will not be lost even if the it is disconnected from the vehicle battery power. RMP signal for air flow & pressure sensors can be adjusted in 12 points in 1% increments depending on fuel settings in +50% to -50%. Or the RSP can be set in increments of 200 RPM
