Sooo, This discussion about the Quick Warm Up System (QWS) (Sorry for thread jack)
I have a UBS55 that I'm trying to get sorted to get back on the road, a while back we put another turbo on it, connected up all the exhaust system etc. Just today I had a look and it's got this QWS butterfly valve in the exhaust....but it's not connected to anything. Normally it would be connected to a black canister on the passenger side of the block.
As the QWS butterfly valve in the exhaust is not connected to anything I have no idea if it's currently open or closed and blocking exhaust flow. Ideally I would wire it fully open, can anyone school me up on which way is fully open?
Thanks in advance
