Surely you mean "keeps the double throttle open when the car gets to operating temperature"?

[Madden]

yes thats the one lol

But the two butterflys  open with the throttle all the way hot or cold.   Is the double throttle just an advanced warm up system?

The double throttle butterflys stay permanently shut (thus limiting power) if the DT solenoid is broken.  Try the car as it is now, you will only get about 5 psi!!!

The DT is not controlled by the throttle pedal.

just tested and getting around 0.8 bar.   So sould i tie the DT actuator back wih some thing?  Still a bit confused here.   I took my inlet elbow off and when i open the throttle all 3 buterflys open

[Madden]

also the car idles at around 850 but when you rev  it goes up to 1500 rpm and then comes back down to 850 rpm after about 20 secs.  is this normal?   I just comp tested the engine and i got 7 bar on all 3 on both rotors.  Well pleased.

Yep, I think you\'re getting confused here. I\'d familiarise yourself with the setup by checking the factory manual.

The double throttle is behind the throttle body assembly, on the UIM itself. You can ensure that it is always open by disconnecting the vacuum line. Remember to seal off the vacuum line in some way.
