So I have used the forum search,and not finding what I am looking for ......Is possible to buy a bluetooth adapter scanner (like the elm327) that you use for diagnostics on a car or truck? The android apps I use for diagnostics most always have a great basic screen for MPH RPM FUEL levels.......I'll probably use an old galaxy tab...and that will also be used for trail mapping ...Not at all interested in a tuner as of yet,and dont care for the price of a tuner to get the features I am looking for...just a generic picture for reference
