Skyline GTR34 RB26DETT Apexi ECU

The Apexi 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 Apexi Power FC should be tuned on a dynomometer by a trained professional.

Engine Tuning
Setting Mode allows full access to the 20×20 ignition timing and fuel correction maps. The user can adjust any portion of this map in 5×5 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. 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.

Monitoring
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 and 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.
