S-AFC


Piggyback Fuel Computer


Modifies air-flow meter signal (pressure signal in some vehicles) to optimize fuel-air ratio; Vacuum Fluorescent Display (VFD).


The second-generation S-AFC is a fuel computer that adjusts fuel/air ratio by modifying the air-flow meter/MAP sensor signal. The S-AFC features 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. On hot-wire vehicles, the Deceleration Air Flow Correction function is capable of curing the erratic idle and stall problems associated with open-atmosphere blow-off valves on hot-wire air-flow meter systems. 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, and Air Flow Correction %.

AVC-R


Advanced electronic boost controller


Highly flexible boost control with revolutionary new functions; Vacuum Fluorescent Display (VFD).


The Super AVC-R is the premium closed-loop electronic boost controller on the market. The AVC-R allows flexible control over virtually every aspect of boost control and adds new innovative functions such as injector pulse monitoring and gear specific boost control. Some key functions include: RPM-based boost and solenoid duty cycle control, scramble boost, self learning mode, 2D ghost map trace mode, analog display mode, real time replay and peak hold data modes. The AVC-R utilizes an ultra-fast microprocessor and a high quality solenoid valve to control boost. The result is ultra-fast response and accurate, stable boost control.
