Great use with support from my tuner! Only one suggestion.
Z1 Motorsports has been very helpful to remotely tune my 370Z, with this app. I have had very few issues with the app itself, other than a few errors, which frankly probably saved my ECU from frying itself. My only suggestion with my experience is to add a simple timer into the start / stop button of the logging feature. With my remote tuning process I have had to log 30 second intervals of data, which a timer would come a in handy a lot!
