the cinquincento is another one that works,

Apparently the PWM valves work well. I might try this on the new 998.

Bosch part no. 0280 140 505

I ditched the Rover throttle body on my other car for a Cosworth one as it has a PWM built in and was easy to get right

On the mini I plan on using a Saab PWM

Perhaps a stupid question but as I never have seen an IACV installed, how do you actually install these (for example like the Peugeot one that Paul is referring to) do you just plump it into the plenum or do you need some kind of matching valve seat to mount it on? I suppose the other side just goes with a hose to a connection somewhere between the air filter and the throttle body. Another stupid question: how can I put a picture directly into a post as you all are doing so often?

I machined a body for mine:



But you can use the Rover body if you can get hold of one.

The Bosch PWM valves are more money but just a couple of hose connections.

To show a picture, first you must have the photo hosted somewhere, photobucket or even the TM front page.

Then you paste a link to the url with [ img ] url [ /img]. Use the Add Image icon.

EDIT: I think that this will do the job:

Will,

Throttle bodies usually have the ports for an IACV of some sort - the valve (IACV) just bypasses the butterfly - either neatly screwed in if the throttle body was designed for it, or external hoses as Paul shows.

Here's mine, far left of photo



Mine is screwed into a tapping on the throttle body so it just bypasses the butterfly and MS2 drives it.
