Apexi SAFC vs Apexi PowerFC, whats the difference?
My cousin Peter just brought an Apexi SAFC for his R33 skyline and he had it tuned and made 204rwkw. It cost him $300 and $250 for a tune. Most people simply assume you can make power and expect 220rwkw. They will both make very close to the same amount of power if both have been tuned correctly. But clearly the PowerFC winds hands down if it has been tuned correctly and has a bulk of its load points tuned. If you have the IGN and INJ tuned in the low load / light load areas the car will feel much better to drive, response will be better and fuel economy better than the SAFC + stock ecu. The main difference is the PowerFC will support more mods and if tuned correctly will feel like a new car to drive. Both are only as good as the tuner. Car 1 – rb25det with SAFC Car 2 – rb25det with PowerFC The truth is that car #2 isn’t likely to make twice the power as the ecu costs twice as much. It all comes down to tuning and how the car drives, average power is the key here. The engine should fee
