WooHoo!! The scanguage is in and seems to be working! Just a short drive and questions, questions. The MPH seems to read higher than the speedo, which reads slower than GPS
I know car makers generally calibrate speedos to run slow but how is the OBDII getting a faster speed? Must be calulated and my tires are not the stock diameter.
The most important value to me GPH seems spot on. I was suprised at the over 1gph when cold at idle. This gives credance to get the car wamed up quick as possible.
