safc
 

hey guys can someone tell me wat a safc by apexi does for your car

why yes, yes I can!

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.

it lies to your computer by altering the air flow signal. Allows you to add or subtract fuel at adjustable RPM increments.

so its sumthing like a chip in a way correct

its a dash mounted computer. you splice into the ECU harness and alter the signals going in

^ You real only ulter one signal. The Air Flow Signal.

No. Chips are usually pre-programmed unless you use a chip such as the RTek from digital tuning. That is a little more then just a chip too. The Apexi SAFC is a user programmable piggi back computer. You Control how much fuel gets injected by using a Throttle Postion vs RPM table.

You can do very serious damage to your engine if you start adjusting the fuel without anyway to monitor the Air:Fuel Ratio. To do that you will need to by a Datalogging Wide Band Monitor.

BTW - Check your PMs
