Have you tried this one ? I do like using bluetooth if it elimantes a lot of cables and boxes (like you see the ALDL2 bluetooth "plugs"); and if there's a app for your smartphone if using that
I haven't but I will, soon.
One of the many apps is called aldldroid.
It's a very useful gadget from what I read. It is pretty capable. Search youtube also.
Data logged a bit trying to see why I got 1 degree retard. Looks like its fuel related. Last pic shows custom gauges- digital gauge, analog gauge, histogram, and bar graph for example. The different color configurations are plentiful as well.
