I had to go and try the three detailed above. First one, tranny temp worked like a charm. Charge temp did not get a value when I tested and Cyl head temp did not return a value either. I canceled out of the menu. I'm wondering if the PID number was correct. For Cyl head temp I put in "221624" and for Charge Temp I put in "2216E0". Also I wonder if the charge temp formula might have an issue with the parentheses or maybe in the last (9/5-3)
