A’PEXi Power FC – Complete Standalone Engine Management
The A’PEXi Power FC is the ultimate solution for those seeking to break free from the limitations of traditional piggyback-style fuel controllers. Designed as a full standalone ECU, the Power FC replaces the factory ECU to provide total control over engine management, making it ideal for high-performance, track, and race applications.
From multi-point fuel and ignition control to VTEC engagement (Honda) and boost management, the Power FC delivers the flexibility needed to accommodate even the most demanding builds.
Key Features:
-
Standalone System: Replaces factory ECU (off-road use only; not OBD-II compatible)
-
Plug-and-Play Installation: No need to replace the engine harness; some models may require minor rewiring
-
Factory Functionality Maintained: Retains key functions like A/C
-
Base Maps Included: JDM-based maps included for faster initial setup (minor tuning may still be needed)
-
Optional FC Commander / Commander PRO: Enables in-depth tuning, data logging, and real-time monitoring
-
Some POWER FC available in Two Versions:
-
L-Jetro (MAF-based)
-
D-Jetro (MAP-based) – requires additional sensor kits
-
Whether you're building a street monster or a dedicated track car, the Power FC gives you unmatched control over your engine’s potential. For optimal results, we always recommend tuning by a trained professional on a dyno with proper air/fuel monitoring.
