Q:
Where abouts do i run the ISV valve??
From a normal 16v, it takes a feed from the metering unit(air-box) and then through the valve to the throttle body.
I'm runnng a turbo, with Digi1 ECU. Where put this inline now??
Also, there is a small breather pipe, just to the left underthen the 16v inlet manifold and on my block(2.0/ ABF) a larger breather(crankcase) both of these need feed from somehwere to??
Any help much appreciated!!
Thnks

The ISV just needs filtered air to operate. The feed is taken after the metering head on the k-jet system so that the air used for idle is measured by the metering head and fuel can then be added accordingly. With the ISV plumbed into the inlet manifold the Digi1 system should handle the fuel part. I would check how the ISV on a G60 is plumbed in. if you are using the ABF inlet manifold I would just try a breather filter plumbed to the ISV if that is simpler and see how it goes.
My crankcase breather is just plumbed to a breather filter at the moment although a catch tank shall be used at some point in future.
