Removing fiav-should I keep the isc?

Just wanting to know what kind of issues I will get from removing both the isc and fiav, or should I just remove the fiav?

Removing the ISC moto will not allow your ECU to increase the idle for cold starts and such. Other than that, I don't see any reason having it would hurt you. Why would you remove it anyway? Unless it's not functioning right (idle surge) then there is no reason to remove it.

I am going to remove the fiav in order to keep the plumbing clutter down and if I can get by w/o the isc, I would remove that also. I will probably go ahead and extend the isc wiring, see how I like it w/o and I can always hook it back up if need be.

I've always had bad luck with the Mitsubishi ICS. I just eliminate them now and use a blockoff plate and raise the idle a little.
