I have an 'Ultra Gauge' but have found the short comings of it and need to upgrade. The information I find while searching is 'That feature isnt working' or a slew of links to download something that may or may not work. On the website it clearly states that data logging can be done via SD card standalone. Im reading conflicting information about data logging with the Tactrix, and I cant seem to get a response from them. Looking for a bit more guidance in data logging and tuning information.
