Contour Enthusiasts Group Archives Forums Modifications Duratec Performance What tells the IMRC secondaries are open?

I keep going back to something I read, when the secondaried open the PCM ramps the fuel map to compensate for more air.

If the IMRC is disconnected the PCM will never get the secondariy open signal and no extra fuel will be added.

How can we get the IMRC to tell the computer the secondaries are open fully when they are totaly removed.

I've looked at a lower intake and there are no switches, it has to come from inside the IMCR.
