Apexi Power FC
Some information.
The Apexi Power FC has been designed for drag racing use. These units have additional functions over the standard version.
* Ignition cut used for rpm limiter - Regular Apexi Power FCs cut fuel feed when the preset revolution limit is reached. At high rpm, there is the possibility of knocking when the fuel is cut in high powered cars. The Apexi Power FC .CPUs cut ignition at the rpm limit to prevent the knocking that could potentially destroy the engine.
*
0km/h rpm limiter setting - Allows for the setting for an initial rpm limiter that is active whilst the car is not in motion. This allows for mainting a rpm level for consistent launches.
Concept:
The Apexi Power FC proudly stands as A'PEX's answer to the constraints and limitations associated with most piggy-back style fuel controllers. The Apexi 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 Apexi Power FC is capable of accommodating even the most demanding performance enthusiasts.
Characteristics:
Currently available only through Power Excel Shops, the Apexi 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 Apexi Power FC Commander, the user can adjust and modify a wide range of settings. By changing various parameters and data, the Apexi Power FC will adapt to any of your performance needs. Since there is no need to upgrade ROM chips or trade in ECU's, the factory ECU can be kept by the original user.
The Apexi 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:
- Engine RPM
- Ignition Timing
- Vehicle Speed
- Air Flow Voltage (Pressure Sensor Voltage)
- Injector Duty Cycle
- Boost
- Knocking Level
- Battery Voltage
- Intake Air Temp
- Water 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 reference.
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 Apexi Power FC's accommodate leading and trailing ignition maps. Honda engines Apexi Power FC's 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 Apexi Power 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 Apexi Power FC also comes preprogrammed with several base maps. (Currently with Japan Domestic Market Vehicle Maps. Minor initial tuning may be required. Please contact your authorized Power Excel shop for more information.) This makes the initial tuning process much quicker. As with all other fuel controllers, the Apexi 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.
Value: Approx 500-600 Pounds
Rarity: These ECU's are no longer in production (Discontinued) for the EP82/EP91.
