Trying to get my ICV working and not having any luck! LOL
Could someone post up screen shots of the ICV settings for closed loop mode please?
I'm using the normal Ford EFI ICV thats on the side of the inlet manifold.
At the moment it doesnt matter if I have it at 100% or 0%, Invert the Valve Mode, or do anything, it is always open (dont know how much though).
Thanks!

run valve frequency at 156Hz, mine buzzed at 78Hz
set at normal, i.e. 0%=off
cranking duty set at 70%
then on the pwm table it goes from 40@5 degrees down to 5@71 degrees
just make linear figures in between.
mine's not perfect but should help you on your way.

No joy, I cant get it to do anything at all!
There is 12v going to it and i've double checked i'm using the correct wire from the MS ECU, so I'm thinking maybe it's dead?
The resistance accross the terminals is 10.5 on the 200 range of my multimeter if anyone would be kind enough to meassure theirs for me to compare?

sounds like you need to phone scotty back up at extra efi and tell him your problem but to me sounds like you've fried you internal warp coil or there might be a problem in the external flux capacitor, hope this helps

If it were just the spring then would it not be fully open and my revs up really high? I will check though!

put 12v across the valve and it should open right up to it's maximum. If this works then you need to make sure the ecu is grounding the valve. One side is supplied 12V, and then the ECU grounds it using a pwm signal, ie turns it on and off very quicky. Get an LED, solder a 1k resistor to one of the legs, and a piece of wire to the other. You can then use this as a test probe. Place the led accross the valve connector (with valve disconnected) and you should see it glowing or even flashing if you set the valve frequency low enough.

there is a spring on the vlaves rod which returns the valve to closed when power is not applied.
you can open the valves up easily, just unscrew the remote mount adaptor, then undo the solenoid from the other part of the body, check the valve opens and closes fully etc, then fit back together if all is well.

Hi karlos i have screenshots of my icv valve settings, it works 100%.
I try to find those.
Ah you have ms2.. here some screens:

sounds like you've fried it as you need to solder a little transistor across the two wires that basically bridges the positive and negative as rick said above, they may say there ecu's can do it but they need a hand to do it

Check your tps value because i have big broblems until i get good tip about that.
Change idledcadvance gauge in dashboard and take a good look if it drives anything. I was amazed when i realized that there is nothing happening in gauge, but after i tweaked settings (tps value when idle) the needle started to move and controlling iacv.

i'm sure it's the middle leg where there is another wire going to it.
basically the patch wires are only relocating the transistor from the board to a heatsink for better cooling.
the other hole from the board goes through another patch wire to the resistor and then back to transistor with the other green patch wire.
i had the same problem where the solder wasn't quite right, it lit up an LED but not good enough to move the valve.

Cheers Rick, I had confirmation back from www.extraefi.co.uk too, problem now is after hooking the ECU back up it wont start the car (no priming, no spark, etc..) and megatune doesnt see it either?!
When i first powered it up I could here the ICV pulsing, turned it off to start my laptop up, plugged it in, turned it back on, and now nothing!!
There is power and a good earth there, and the middle LED flickers on when i power up like it normaly does, but thats all I get?!
I did not touch anything else when I had it apart and it soldered back on with no complications so I dont no whats happened.
Probably going back to be repaired I think is the only answer now!
