So I just installed a new Scan Gauge II. Do I have to do anything or should it program itself. I changed the engine stuff ( its was set to 3 liter engine but mine is a 1.8, so I made the adjustment) but other then that it seems to be doing fine. I went about 60 miles and it says that my avg is about 39mpg. Also, the MPG seems to differing allot is that normal? Like it is never staying the same, but I am assuming that is normal since my MPH and RPMs are always changing. Any advice with the hookup will be greatly appreciated.
Scan Gauge II Installation?
All code 4
