i have a ls1 conversion in my car, with a 160 t-stat, aluiminum radiator, and dual electric fans. There is one sensor that is located on the front drivers side cyl head that reads the water temp for the ecu. i put a sending unit for an autometer water temp guage on the rear on the passenger side head. While idling, the guage for the ecu reads a consistant 195-196 while i had a scanner pluged in. at the same time, the guage kept rising and rising to like 220-230. just trying to see if there is an explaination for this? thanks for any help!
