The Power FC proudly stands as Apexis answer to the constraints and limitations
associated with most piggy-back style fuel controllers. The Power FC is a
complete, stand alone, total engine management system capable of handling
virtually anything thrown in its path. From multiple point fuel and ignition
control to VTEC engagement (Honda applications) and boost settings, the Power FC
is capable of accommodating even the most demanding performance enthusiasts.
The Power FC replaces the factory ECU and controls all engine parameters. (Off
road use only, no OBD-II) Installation is as easy as replacing the factory ECU.
(Some minor rewiring is required on select vehicles.) The factory engine harness
does not need to be replaced and all critical accessories such as air
conditioning continue to function. By using the optional FC COMMANDER, the user
can adjust and modify a wide range of settings. By changing various parameters
and data, the Power FC will adapt to any of your performance needs. Since there
is no need to upgrade ROM chips or trade in ECUs, the factory ECU can be kept by
the original user.
The Power FC operates off of three Main Menus. These menus are: Monitor,
Setting, and ETC.
In Monitor Mode, the Commander can display up to 10 parameters of data in real
time. Monitor Mode can display:
Air Flow Voltage (Pressure Sensor Voltage)
Injector Duty Cycle
Intake Air Temp
In addition, there are 4 display patterns allowing 1-8 parameters to be shown on
screen at once. The data displays in numerical real time values with the option
of a real time 10 second graph display. Peak Hold values and Display Hold
functions only require the touch of a button. The Map Trace Mode allows Ghost
Map Tracing of the Fuel Correction and Ignition Timing maps. This allows the
user to visually see what point of the map is being used in real time. The Ghost
Map Trace function leaves markers on the used portions of the map for easy
Setting Mode allows full access to the 20x20 ignition timing and fuel correction
maps. The user can adjust any portion of this map in 5x5 sections. Air flow
correction values can be entered for vehicles upgrading air flow meters.
Injector pulse correction menu is used when upgrading injectors on the engine.
The Acceleration Enrichment Correction function improves response under hard and
sudden acceleration. The Cranking Fuel Injection menu corrects the amount of
fuel when the engine is being cranked, or when the water temperature is cold. A
separate Water Temp menu allows fuel correction according to water temperature.
The RPM menu allows rev limiter settings and idle RPM levels. Access menus also
vary according to specialty engines. Rotary engine Power FCs accommodate leading
and trailing ignition maps. Honda engines Power FCs allow for VTEC control.
Complete boost control is possible by using the optional Boost Control Kit (Not
necessary for vehicles that come factory turbocharged.). Changing data is easy:
just access the desired point on the map or data, and push the FC COMMANDER keys
in the appropriate direction.
The ETC Menu contains utility parameters such as: version information, LCD
screen Brightness, and Initialization of all Data. In addition, the ETC Mode
allows the user to monitor all factory sensors through one screen. This screen
can tell the user if any sensor is in use or malfunctioning.
The Power FC also comes preprogrammed with several base maps. (Currently with
Japan Domestic Market Vehicle Maps. Minor initial tuning may be required.) This
makes the initial tuning process much quicker. As with all other fuel
controllers, the POWER FC should be tuned on a dynomometer by a trained
professional. A high grade air/ fuel ratio monitor is also recommended during
tuning to ensure best results.
Very Good Condition.
