Good catch. The problem is that the spec says that all three of the fuel
rail pressures you found should be exposed to the user as "FRP". I
suffixed an extra letter on 0x23 to avoid the collision and thus make
them uniquely identifiable, but forgot about the other frp.

So... I've suffixed an extra letter on 0x22 ["m" for "manifold"], which
should resolve that. Thanks!
