I am deleting the IACV on my 1JZGTE since I am going with a Microtech Standalone ECU, from my understanding it only works with stock ECU. But here's my question since I can't find any clear info on it: What is done with all the coolant lines on the intake manifold after you remove the IACV? Do you just block all of it and on that side of the engine only run coolant to the oil cooler? There would be no reason to keep coolant flowing through the throttle body/intake manifold except to keep it up in temperature in very cold climates, correct?

I know this is a 2J diagram, but I am using a 2JZGTE waterpump, so I thought this illistration works best.

Shouldn't. It's a small hose. The big cooler hose I would loop if switching to a full flow oil cooler setup.
