My 2014 KXF450 I have just bought came with a power commander fitted and tuned in for the bike along with being race tuned etc.

Does the power commander override the three EFI mapping plugs for the bike? I tried changing the plugs but couldn't notice a difference so am wondering if the power commander is essentially doing the job of the EFI plugs just in an aftermarket form?

I have come from a YZ250 so am trying to understand how fuel injection works with these plugs let alone how an aftermarket power commander works.

Cheers.
