The Power FC proudly stands as APEX’s 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.Currently available exclusively through Power Excel Shop the Power FC replaces the factory ECU and controls all vital 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. Since there is no need to upgrade ROM chips or modify ECU, the factory ECU can be kept by the original user. The Power FC also comes pre-programmed 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 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.– L- Jetro Kits are MAF based– D-Jetro Kits are MAF to MAP Sensor conversion kits– D-Jetro Kits require optional sensors & harnesses
