But temp of coolant entering the block would be interesting than two exit readings.
Glad you found the problem though ... Jim S.

Thank you, Rusty and John....today I went to the airport and ran the engine for a couple of minutes and checked the water temp readings. ECU water temp readings were -24 C. I cut the wire that shared the water temp sending unit with the ECU, and the temp immediately went up to 48 C. That's more like it. The engine has a stock water temp sender next to the oil pressure switch. I will try using that to send temp information to my engine monitor. If that does not work, I will install another temp sending unit like the one that came stock in the water pump housing.

Of course all the time I spent programming maps are out the window, as they were programmed with erroneous water temp input. Fortunately, I have finally gotten comfortable and familiar with the programming, so it won't take long to reprogram the maps to suit the correct water temp readings.

Thanks again for informing me that I could not wire two devices to one sending unit. Now, the after start enrichment works properly, and my ECU should also function better with proper temp inputs. Paul Conner
