tumpang tanya, how much improvements does POWER FC helps ?
noob learning here :)
Apexi PowerFC is a "standalone" engine management system. It is designed to completely replace your existing ECU and allow you to program it - to "tune" the various aspects of the engine and others. As a standalone, it will also take control of your AC, lights, diagnostics, etc. besides taking control of ignition and fuel injection.
As for the improvements, it depends on the tuner and your goals. In some applications, we will tune our calls to the point where a piggy back or standalone EMS is required to get the most out of our settings - because the stock ECU was not designed for it. For example, trying to hit 1200HP with a massive turbo. The stock ECU is not designed to do this and so we must exceed its capabilities.
Piggy back EMS is Apexi SAFC and Apexi VAFC (for Vtech). It is capable of adjusting your fuel maps to exceed the stock ECU capability and sticks "on top" of your existing ECU - hence the term piggy back. It does not replace your stock ECU.
Do note that Japan Apexu is no longer supplying PowerFC for the older model of cars but you can find some of them from USA.
