A´PEXi Electronics Descriptions

It was less than five years ago that A´PEXi hit U.S. shores with its first line of electronics. The enthusiasm for A´PEXi electronics was overwhelming. A´PEXi has since invested heavily in the electronics division to develop products that have become known to be the best-of-breed among piggyback computer systems. A´PEXi now builds fully programmable fuel injection computers that can be used in place of the factory ECU. You will find that A´PEXi electronics are the preferred choice among many race and performance enthusiasts today.

APEXi Electronics Applications and Accessories

APEXi SAFC II

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 SAFC is a fuel computer that adjusts fuel/air ratio by modifying the air-flow meter/MAP sensor signal. The SAFC 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 SAFC 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 %.

APEXi VAFC II - Vtec Controller

Piggyback Fuel Computer with Integrated VTEC Controller

Modifies manifold pressure signal and alters VTEC engagement point on Honda VTEC engines; Vacuum Fluorescent Display (VFD).

APEX introduces the first digital fuel computer that combines fuel computer functions with a VTEC engagement controller. The V-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. The Fuel Adjustment function considers wide/narrow throttle and low/high camshaft settings, from which four different fuel maps are created (wide-low, wide-high, narrow-low, narrow-high). The integrated VTEC Controller adjusts the point at which the engine switches from the Lo to Hi cam during acceleration, as well as when the engine switches from the Hi to Lo cam during deceleration.

APEXi AVCR Boost Controller

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.

APEXi Rev Speed Meter

Like the original, the new Rev/Speed Meter GP is a complete multi function measuring device designed to measure and monitor data such as vehicle speed, engine RPM, and elapsed times. However, the strength of the new unit lies in its differences. Probably the most obvious being its completely redesigned look. This new aesthetically pleasing model was crafted to match the likes of other highly popular A'PEX electronics such as the SAFC and the AVCR (Boost Controller). The new screen utilizes the easy to read VFD (Vacuum Fluorescent Display) with built in light sensor used in many of A'PEX's line up. The new unit also delivers a host of new functions. One of the most exiting of the new features is the option to utilise the revolutionary A'PEX G-Sensor.

APEXi Auto Timer

The Apex Auto Timer allows the vehicle to idle for a preset amount of time after the ignition key has been removed. In turbocharged vehicles this prevents hot oil in the engine from coking up in the lines. Hard driving can raise engine oil temperatures to dangerously high levels. Proper cool down is essential for a healthy turbo and engine. In normally aspirated cars, the Auto Timer can also be used to warm/cool the inside of the car without having to sit inside. The Auto Timer stands as a technological marvel. The pen shaped, compact size makes the Auto Timer one of the smallest turbo timers on the market. This allows a clean and stylish installation virtually anywhere inside the car. The unique multi angle joystick button allows easy navigation through the many feature menus. Upgraded in every way from the previous model, the new Auto Timer can automatically determine the necessary amount of after idling time. A Manual Mode allows the user to preset desired idling times from 0 sec.~10 minutes in 16 increments. By inputting O2 sensor voltage, the Timer can also display theoretical air fuel ratio. Since the Auto Timer uses the factory O2 sensor which is primarily designed for emissions, the readings may not be as accurate when the O2 sensor is cold. A'PEX recommends that the O2 sensor readings be compared to a high grade"tuning" O2 sensor for comparison. The Timer can also display critical data such as O2 sensor voltage and Battery Voltage. To prevent potential theft while running, the handbrake safety feature shuts off the vehicle when the handbrake is released without the ignition key.
