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. :D . Is there anyone that has a link or is able to tell me everything that affects idle including sensors? Thanks in advance.

It has everything to do with it. You read wrong.
|
That's right. The thermowax causes the fast idle cam to rotate and create the high idle. Without it no fast idle.
|
wtf i just did the tb mod, pulled of the thermowax and it still does the accelerated warmup only it doesnt hold at 2k until warm just drops back after a few secs
|
There are more than one thing that does the fast idle though. The Cold Start Assist stuff also does that I think. YOu might want to take it off also.
|
the 3k asssisted warm up has nothing to do with the thermowax and 1500 rpm cold idle.
|
cold startup is long gone maye its the bac thats still on there

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.
Santiago PS- If any mod sees this can you please delete the incorrect post. Thanks! |
god I hate the BAC
|
so take it off :)
|
and destroy it :ar:

Originally posted by silverrotor What about the relevance of the Water Temperture Switch found at the lower driverside Radiator? That too Is Involved In the 3k warm up. |

How does It differ with the s5? I didn't know their was a difference within series.
|
They don't have a radiator temp switch.

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. |
so the bac tells the ecu the engine is warm?
|
Thanks...good to know. Admittingly, I don't find myself viewing to many s5 EB's.
Coincidently, I bought this sensor brand new last summer, along with every other Water sensor. I've since ditched It when I Installed my Koyo Radiator. |

im so cunfused. oh well. ill just thank mazda that it works and not wory about all the nity grity EMS junk
|
better hope you don't want a standalone EMS later on then :)
