IAC Lock in VemsTune

[Ascona 400]

I noticed that there is a menu option under the "Tools" menu called "IAC Lock", is this function implemented?
If so, i guess it basically does the same thing as the "mdi.." command?

I'm trying to figure out why my IAC won't work, I've verified the wiring (with a diode), tried all possible settings and tried with a different IAC-valve.
And nothing seams to do any difference, the IAC-valve won't move a bit.. Unfortunately I don't have any oscilloscope..

I'm starting to run out of ideas  ::)

it does in fact work, as i used it last night  :)

i'm running 1.1.69 firmware.

its only active when the menu is up. As in, if you make a setting and close the window it no longer forces the output

only odd thing is it works from 0-255, whereas the PWM settings work 0-100.  So the values don't always translate over to idle settings.

maybe set it to 255 and see if you get voltage on your pins?

Otherwise move to another output?

Perfect!
Thanks for clarifying that the function works!

I'll try to set different values and see if the voltage changes over the IAC.
An oscilloscope had been nice in this case..

I have fixed all trigger problems and now have my engine "running" but idle is ~2500 RPM, so I'm looking at IAC to get this down.

So, I can remove my IAC from the throttle body and manipulate the lock to see it move (if it can)? Correct?

Yes.

You can do the same via max and min on in the PWM control, but this is easier. I guess a slider control would be the ideal quick movement tester.
