What are the major differences, i have been running through the web
looking for information but unfortunately the sites that i find about S-
AFC II are only in Japanese. Also what is the major use of the SAFC ? I
am currently contemplating whether i should get it or not.

The S-AFC is a fuel computer that adjusts fuel/air ratio by modifying the
air-flow meter/MAP sensor signal. It has a user-definable, eight-point,
adjustable fuel curve that can be set in 500 RPM increments. The range of
fuel adjustment is +/- 50% at each of the user-defined setting points.

The S-AFC is capable of monitoring and replaying the following data
channels in Numerical, Analog Meter and Graph displays:
Intake Manifold Vacuum/Boost Pressure
Air Flow Capacity
Intake Manifold Pressure
Karmann Frequency
Engine RPM
Throttle Position
Air Flow Correction %


On the other hand the S-AFC II is an improved version with more fuel map
points (12 if my memory serves me right), has a password feature, 2 set of
maps and a knock sensor.

Nuttin' to do with turbo or non-turbo. Applicable to both types of
engines. Just that with forced induction, the gains are more as compared
to NA.
