After my issues with a bad trans temp gauge i found a guy selling his for half price thats only 6mths old. im looking for some codes that i can use on my scangauge for a 2000 f250 v10. i checked the web site but was wondering if there was more. specifically i would like the engine coolant one thanks alot. so far this thing is awesome!

 

well sorry i asked to soon. i actually read the manual and found the water temp setting. this thing is still cool. but on another note how much temp differance would the pcm reading and say a gauge in the test port be?
