I have an older version 3.17 ScanGauge II I recently started using in a 2008 Dodge Grand Caravan with the 3.3 liter flexfuel engine. I had used it with a Chevy Colorado many years ago and recently found it so I thought I'd start using it to help improve my driving habits. Not sure if this is normal... When watching the instant MPG readout, if I am coasting in gear at any speed over approximately 20mph, the numbers don't go to 100 or 999 or --- like they do with the factory instant readout in my 2017 Jetta 1.4t. They'll read no higher than about 60mpg. I'm curious if this is normal or if I could have a leaky injector, fuel pump issue, or something else.
I haven't had access to my Jetta to try the ScanGauge in that car.
