I'm wondering if the coolant lines running to the IACV are needed when running an AEM EMS? I don't drive my vehicle in the winter and have already bypassed the throttle body with the coolant line. I'm wondering if I can cap the coolant lines or if my idle will become erratic?

 

I took mine off, no issues with idle or start-up.

 

Hmm so you disconnected the coolant lines with no issues? I'm pretty confident the cooling lines are just to prevent icing in very cold conditions but just wanted to hear other opinions.

 

Do u guys have any pics of the IACV bypassed?
