I got my scangauge a few days ago and am getting very high mpg readings like 60- 9999mpg. In the manual it says to adjust the fuel cutoff so it is about 4pts above your TPS reading at no throttle. My TPS is at 15 while off the throttle so I set the cutoff to 19. Still same problem. The mpg while on the throttle seems about right but when I let off the gas it slowly climbs to 9999.
What did you guys set your cutoff to? Any other tips would be appreciated. Thanks!
What are some good x guages that you guys use.
