Just installed it and here are some observations. (1) On my Honda Accord Hybrid, I do get oil temperature, but no outside temperature nor transmission temperature. (2) The range of the gauges is set for Celsius and if your switch the units to Fahrenheit, then your water temperature will quickly be at the max of the range on the gauge. (3) No link has been provided to any future firmware updates. (4) Configurability is OK, but a little bit tedious, (5) does not seem like it can read DTCs. (6) some settings are not described in the manual.I got it mainly to monitor water and oil temperature on my Honda Accord so that works for me.
