Alright, So I saw the debate in other threads about these sensors, but once we are using squirt for fuel and spark, I don't see any need for the stock CTS or IAT. Can anyone tell me what the use of the stockers is if we are running spark and fuel from the squirt??

It's pretty easy to have the MS control the radiator fans. You hook one side of the relay to +12 and the other side to the MS, which stays at +12 if the fan is to be off and gets pulled to ground if the fan is to be on, which will pull current through the relay turning it on.
For idle control, the stock ECU uses the coolant sensor, so if the stock ECU isn't able to get correct information about the tempature of the coolant the idle may be a little shaky.

I know the ECU uses it for idle but the squirt is running fuel even at idle though, so the ECU won't be running it.

The stock ECU will still be running the idle control valve on the throttle body. There is no interface yet to have the MS do that to my knowledge. Coolant tempature is an important variable in how the idle valve works.
I have a resistor in place of my stock sensor which makes the ECU think that the coolant tempature is always 180 degrees because I didn't feel like drilling and tapping the thermostat housing. The stock ECU can deal with it to some extent, but the idle quality isn't what it could be.
