how does the lt8 control idle? i have looked at the wiring diagam on the web site for the s4/s5. and it does not show any kind of output or idel control for the engine.

 

i must of asked a realy stupid question

 

some one needs to throw me a bone, i have done some serchen but havent come up with any thing. the wiring diagram shows nothing for ide controle on microtech web site

 

The idle valve connects to the aux output as shown in the 13B wiring diagram (back of manual).

However in order to enable this, the Microtech has to be sent back to Microtech to be programmed. The cost is $165 or so as I recall.

And for some reason, they told me that the aux input is lost during this process...
