I suspect you could make it work via a manual switch or lever ? although I wouldn't know if it would add any benefits.

My imrc has thrown up the eml since day one, I work at a Ford dealership and have taken the unit apart 3 times now, each time I can find nothing wrong with it and each time I check the actually intake system, all is working really well.

So I've come to the decision that I will just put up with the light being on.
