What does a APEXi SAFC do?
APEXi SAFC II Modifies air-flow meter signal (pressure signal in some vehicles) to optimize fuel-air ratio; Vacuum Fluorescent Display (VFD). The second-generation SAFC is a fuel computer that adjusts fuel/air ratio by modifying the air-flow meter/MAP sensor signal.
What is a SAFC tuning?
The A’PEXi SAFC 2 is an electronic fuel-tuning device used to optimize the air-to-fuel ratio in modified engines. Considered a piggyback tuner, the SAFC 2 connects into the engine control unit, or ECU, and modifies the oxygen sensor signal according to your custom settings.

Is an Apexi ECU good?
The PFC is a great ecu its a full stand alone ,it by it’s self will make no more or less power than any other ems out there. It’s plug and play . meaning you install it and start and go tune your car . If you just plug it in don’t expect it to make 1000 rwhp or so .

What happens if you tune the ECU on a SAFC 2?
The ECU compensates for these settings with an increase or decrease in fuel injection. If you do not have prior knowledge and experience with ECU fuel tuning, have your SAFC 2 tuned by a trained professional. An improper tune can cause substantial damage to vital engine components.
How does the SAFC 2 work?
Considered a piggyback tuner, the SAFC 2 connects into the engine control unit, or ECU, and modifies the oxygen sensor signal according to your custom settings. The ECU compensates for these settings with an increase or decrease in fuel injection.
How do I tune the SAFC 2 to a specific RPM?
Program the initial settings of the SAFC 2. Use the button controls on the device to navigate to the “NePoint” menu from the main screen. This allows you to set the rpm intervals for fuel tuning, such as one interval at every 1,000 rpm. Navigate back to the main screen, then select the “Th-Point” menu.
