APEXi Power FC Mazda RX-7 FD3S (Ver. V)

The A'PEXi Power FC is a complete standalone ECU that replaces the factory ECU to provide total control over engine management. It is ideal for high-performance, track, and race applications, offering multi-point fuel and ignition control, VTEC engagement (Honda), and boost management. It's a plug-and-play installation for many models, retaining factory functions like A/C, and includes JDM-based base maps for faster initial setup. Optional FC Commander or Commander PRO enables in-depth tuning, data logging, and real-time monitoring. Available in L-Jetro (MAF-based) and D-Jetro (MAP-based, requires additional sensor kits) versions.
