S-AFC

Programmable @ 8 points
500 rpm increments


S-AFCII
Programmable @ 12 points
200 rpm increments
Knock Sensor monitor (for cars with a knock sensor)
Drive Voltage Warning
Various User customization settings/display settings/warning settings
Password protection
Internal memory - if you disconnect the unit, you will not lose your programs or settings.


The major difference is the S-AFCII can house 2 separate programs. You can program one for the street, and one for the track, or whatever you prefer.

I have one what's your question?

bbarbulo, what I never understood about Safc is that, sure, it fools the ecu into thinking that the car is getting more air by giving false MAP sensor readings... so the car will run richer/leaner, but doesn't the o2 sensor notice this excess/deficient mixture and then tell the ecu to RE-compensate, thereby eliminating any real effect?

Am i totally wrong here?

ultimately, all fuel control is overtaken by the S-AFC. O2 is an input into the SAFC, so whatever the ECU could do, the SAFC can do too... except the ECU maximum injector parameter is 320cc, so 440s are out of the question for a stock ECU.

As I understand, the SAFC does NOT fool the ECU in any way - it's not a hack like that - it's literally a true fuel controller, and based on certain inputs it's able to run your injectors as per the tuning maps that you program into it. The stock ECU only have a restricted range of fuel maps that are just not designed for pressure conditions like boost.
