MSDroid

★★★★★ Very useful app. Sometimes I have to close it a few times before it connects to my ecu properly, but it's damn good for a free app.

★★★★★ I run this on my head unit, so it is always running while I drive. The intuitive interface lends itself well to quick, on the fly adjustments to the tune. It takes me longer to find settings in TunerStudioMS than it does in this app. The logging feature is seamless and useful as well. MS Droid logs data from the Android device's GPS and accelerometer sensors in addition to all the standard megasquirt fields. Logging is configurable to start upon connecting to the ECU. The logs are compatible with MegaLogViewer. MS Droid can optionally upload logs to Google Drive, but this only works if the log is stopped when an internet connection is present. If I may suggest a feature improvement- It would be very useful to have a single button that synchronizes the current tune and uploads the current/latest log to Google Drive. This would allow for seamless synchronization with MegaLogViewer. The process would look similar to this: record log and optionally tweak settings while driving --> send latest log and tune to MegaLogViewer through Drive --> tune offline --> synchronize modified tune with Drive --> ms droid asks to optionally load modified tune from Google Drive upon connecting to the ECU when an internet connection is available. A lot of people are requesting Tuner Studio's auto-tune feature in this app, which would be useful, but good synchronization of tunes and logs with a different computer running Tuner Studio+MegaLogViewer could be just as useful in many cases. Trevor, thanks for creating and supporting this great app! It has become an essential part of my car.

★★★★★ Finally, got logs transferred and working from my phone to laptop, tunes not as reliably (errors) so I won't be using MS Droid to change the tune. It's still great for gauges without dragging the laptop around.

★★☆☆☆ Can't get it to connect. Have heard it's really good but super sad I can't make it work. Would really love to get in contact with the developer but haven't had a response to my email. :-(

★★☆☆☆ Could never get it to connect to my MS3 Pro Evo. Missing definition file. I've done research for hours and hours could not get it to connect to my ECU. (My laptop with EFI Analytics Bluetooth official adapter works perfectly, even shadow Dash Ms app). So thinking maybe It was one of those apps you need to pay to play, I went ahead purchasing the pro version hoping it would fix an internal bug with the app. Still no luck. Emailed the developer several times, and he never replied.(8+ weeks now)
