Thermowax
Yeah, so I read here that the thermowax does not have anything to do with the 3k warm-up. I removed it and now there is no 3k warm-up. Is it true that thermowax has nothing to do with it? If that is true, then damn I have something else wrong. Also, is there any substitute for the thermowax, aside from the brick or, as I am using now, a raquet. . Is there anyone that has a link or is able to tell me everything that affects idle including sensors? Thanks in advance.

The thermowax is a purely mechanical device that opens the primary thorttle a tiny bit to increase idle speed to 900-1000rpm until the coolant warms up.
The 3000rpm warm-up is triggered by the ECU, which opens both the AWS solenoid valve and the BAC valve.

Ok I guess I can't edit my earlier post but I was wrong. I didn't do it on purpose I just didn't remember that it was the AWS and BAC through the ECU that did the 3k warm up. My bad.

The thermowax is not controlled in any way by the ECU, but if you remove it then a bit less air than normal will be passing through the TB when you first start the engine. So instead of 3000rpm you get a slightly lower rpm.
The Accelerated Warm-up System is still only being triggered by the ECU, which uses the BAC valve and AWS solenoid to get the really high idle.
