Can my tuner disable IACV in crome? Is it safe to disable?

IACV is only important for cold start ups correct? Will my car run normal after it is warmed up? I have a y7 and don't want to rewire.

 

It isn't just used for cold start ups. It is used all the time.

In almost ALL cases you want to keep the IACV. If you disable it in crome.. which only disables the code it will usually have a rough fuel cut or hesitation around 1800 rpm.

So IMO you should try to either switch to a Y8 manifold or something with a 2 wire IACV.

 

I am getting tuned in a couple days i don't have time to switch. If i switch in a few weeks will it effect my tune?

 

i've seen nothing but bad news using the disable IACV feature in crome, weird **** happens and it hits a really low rev limit.

You can make the car run without one, but you'll have to have it hanging there plugged in to not get the IACV code.

 

So if i don't disable it in crome will i still have weird problems until i switch to a 2 wire setup?

 

Correct. Either switch to a 2 wire setup or switch to an engine management solution that doesn't have issues with a disabled iacv.
