Hey All, just trying to put a bit in to a site that has helped me greatly with so much archived info....
Anyway, aparently this is a problem between 1JZ & 2JZ's running the Emanage Ultimate with coolant temp connected, problem being that the car at cold start runs like a pig and can also run rich when at operating temp. Found myself tinkering today to find that even though all jumpers were in correct settings as per user manual and using the water temp adaptor from trust my reading at operating temp for coolant was at a super cool 21c and IAT at a dream reading of 5c.
Trying not to make this longer than it needs to be so long story short changed the jumpers concerning these two sensors (I believe they were JP13 & JP14) to the position as if they were connected to knock sensors and voila! IAT @ around 30c and coolant temp a realistic ~80. May only be specific to me as I am running a universal harness but hopefully this'll help out someone else caught scratching their head like I was

Yep, for any 1JZ/2JZ powered Toyota = no need to change jumpers. Just use the correct ultimate wire and setup through interface.
