Well, I loaded the lastest beta 2.7 flash on the ADR today and updated the iPhone app to the latest beta release 1.9.42 (I think that is what it was) and am testing it. I only got a couple of drives today and have not really had a chance to get a good impression of it yet. I noticed on the data logging that I did that the instant mileage and trip fuel use were not updating with data for some reason, so not sure if this is a bug, or if I need to reset something to make it start working. I will play around with it over the next few days and post updates to this thread.
So far, my first impression, is that it fuels harder and faster than the standard tune I was running before, so I like that. The truck has really snappy throttle response. I will need to be careful not to smoke the clutch, perhaps.
