S-AFC II fuel computer can now be enjoyed by European car enthusiasts! The Super AFC (Air Flow Converter) Select is based off of the world renowned S-AFC II piggyback subcomputer. The S-AFC Select 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 Select 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 Select utilizes a VFD (Vacuum Florescent Display) to display critical data in three different modes.
