Just doing a search for Scangauges on eBay as I know someone who is searching methods for better mileage for his truck and I installed my Scangauge in it and he loved it (now I need to find him one of his own).
While searching I came across a
DashDyno. It seems pricey but does have a lot of extras, IMO not $200 worth of extras. Also, here's the
spec page.
Just curious if anyone has input. I don't have anymore OBDII cars that I regularly drive as I went old school diesels but once my Smartcar comes in, I may consider this as an addition though I don't plan on driving it too much once I get it.
