Getting close to assembling the engine, it will be a joint effort between me and a local shop who will oversee my work as this is my first engine build.

Anyway, engine is a 3.4 l with the high compression Mahle P/C's, dual plugged, Rasant system with CoP, Dougherty DC 35 cams, Eisenmann exchangers and CarGraphic exhaust.....and of course PMO ITB'S controlled by a Motec M130.

The tuner tells me that the PMO's are quite good, but they are not the best at idling due to the rapid change in airflow as the throttle plates move off of the rest position...and he asked about an idle air control valve. He said if I want an idle below 1000 rpm and especially with low temperature (like below freezing), the ITBs could not do it...and I don't like high idling for a number of reasons.

I checked out a bunch of threads on this forum and there is no conclusive answer or even a successful install of an IACV for any ITB set up.

My current thought is to use the Haltech IACV tied into the little ports on the PMO's that the MAP will use, but I worry about disturbing the MAP signal, albeit only at idle as the Motec would close the IACV at anything over about 1200 rpm.

So, very curious as to experience by anyone with this. I see the GarageTime guy on YOUTube (great channel) is going to do this but has not yet, so looking for anyone who has done it successfully and is willing to share the parts used and the set up.

Much appreciated and I will post my experience once I get that far....have another work gig coming up, so I may end up being on the road again pretty soon.....
