Can you reflash the PowerFC with new code and/or different versions of the Apexi code?
The newer model Apexi PowerFC’s have a different model NEC processor and also feature an onboard connector, possibly for reflashing internally by Apexi staff and / or authorised dealers etc. If you open up your PowerFC unit and you see a processor which has; NEC Processor: 78P3 CPU Not reflashable NEC Processor: 78F4 CPU Reflashable For more information on this check out the thread on the RX7 forum by FastHatch. He has done some extensive research on this and found that they are reflashable and can be altered providing you know how.
