APEXI S-AFC II

The Super AFC II (Air Flow Converter) is the industry standard for sub computer fuel control. The S-AFC II is designed to fine tune and "squeeze" power out of existing engine setups by allowing the user to modify the fuel curve with precision accuracy. Since the act of simply bolting on performance products does not make maximum horsepower, the S-AFC II allows the user to calibrate the fuel system in accordance with performance upgrades as they are installed. The AFC modifies the air flow meter/ pressure sensor signal voltage going to the factory ECU (Engine Control Unit) to change the amount of fuel injected. The S-AFC II utilizes a VFD (Vacuum Florescent Display) to display critical data in three different modes.

Features for the S-AFC II include:
Newly designed case and user interface, single button menu navigation, 12 point fuel correction in 200 RPM increments, data storage for two different correction maps, password protection, integrated knock monitor, and 4 different display options.

The S-AFC II, while not completely universal, comes preprogrammed with 15 of the most commonly used air flow meter/pressure sensor maps. By setting the AFC to one of these programs, the user is able to adjust injected fuel amounts by +/- 50%. 12 user defined RPM adjustment points allow for fine tuning in 200 RPM increments. Fuel can also be adjusted for part or full throttle situations.

The Deceleration Air Flow Correction cures erratic idle problems for Hot Wire vehicles equipped with an open atmosphere blow off valve. The S-AFC II can also display an incredible amount of data including: Air Flow Capacity (Hotwire and Flap Type only), Engine RPM, Throttle Position, Pressure Sensor voltage, Karmann Frequency, and Air Flow Meter Correction.

The S-AFC II displays data in three different modes: Numerical, Analog, and Graph. Numerical Mode allows the user to monitor up to four different parameters in numbers and also shows peak hold values on demand. The Analog Mode displays up to two values in an easy to read meter style display. Peak Hold is also included in this function. The Graph mode offers real time graph plotting with a Ghost map trace feature built in. The graph can replay movement up to 60 seconds.
