I used to run 1.0.73 and for the lasy year and a half I've been using the 1.0.78fw. Both work the same way regarding the outputs.
There is one more thing it can be.
Go into "Injector Outputs", on the left side you will see 0-1-2-3-4-5-6-7 from the top to the bottom.
Go into the "6" box (second from bottom) and type in the number 64.
This will activate the "Injector 06" Output (ECU Pin 6)
Your idle valve should start working immediately.
Make sure the Idle Valve Channel is set to "6" and not "i6"
good luck!
