Default What resistor to put inline of IACV? EF9?

I know jason knows this one, what type of resistor or whatever do you put on the IACV circuit if you want to delete it without having a check light? I remember you talking about this awhile back, my itb setup is together, and it looks a little tacky zip tied to the firewall, lol.

RadioShack.. 10w 10ohm.. Part Number #271-0132 should work fine.

So connect both wires together with a resistor in bewteen right? and it wont get a check engine light? wont the ecu freak out if it cant adjust the idle air control valve? Right now the iacv wont trip for about 1/2 hour of driving.

The IACV doesn't send information to the ECU. It seems that it just "checks" to see if it's there. I run this same setup on my car because I have (had, I have the LS now) Y8 automatic intake manifold which doesn't have a spot drilled for the IACV on the back. Tested positive to work 100%.

If my iacv is bad and i due this would it stop the crazy idle thing? The only thing that would control the idle is the ecu and idle adjuster screw then right?

Cool thanks. I was wondering about it cause i read somewhere awhile back that you did that to yours and was thinking about it. Thanks again.

i know im slow, but other than if yours is broken, what would be the benifit of doing such to my IAVC?

Race setups with custom manifold don't have IACV, Y8 automatic intake manifold does not have typical two wire IACV and ITB setups will not use an IACV.
