download a "screen capture" program (I use ScreenHunter) so we can see what you see on your screen.

I managed to find what you were talking about with the i6 to 6.

But it made no real change unfortunatly. :(

I am considering upgrading the firmware in the unit to see if that makes any difference.
Concensus?

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!

Update.

I put the 64 in injector outputs and that instantly brought it to life.
Got it nicely dialed in.
For anyone who searches this issue and reads this.
Go into the terminal mode and using the mdi followed by two hexidecimals to figure out the range for idle control P
idle control I and D need very small numbers for the Bosch 2 wire. On my setup I was 2 and D is 1.
iac increase limit of 10 was more than enough. Iac decrease limit was much higher (150) but any higher I and D values resulted in oscillations.
