Got my Scangauge 3 with the mount ordered as a bundle from Spiker Engineering. Did modify the attachment on the mount for the magnetic one which comes with the Scangauge 3 and combined both. Also put some aluminum tape on the back for the sun, probably a marginal improvement although all small bits help heat wise. May still bend the mount a bit to get the optimum angle to the driver although it can now also be more easily watched from the passenger side.Installed an Ultra Gauge 3 and fixed an issue with the auto rain sensor where it wasn’t properly affixed to the windshield.

Already set alarms on coolant temp (at 230 degr F) and AT temp 1 (at 230 degr F as well). May still adjust does researching that some more.
Also getting the reported 408 or 418 degr F from the coolant sensor upon shutdown which triggers the alarm until it turns off 15 sec later. I may look at writing Scangauge to see if they can provide a software update which immediately shuts down the system upon seeing 0 rpm. Already tried the "COM" mode as suggested for hybrids and start/stop vehicles, but that obviously does not resolve the issue. In fact prolongs the gauge and alarm shutdown beyond the vehicle stop communicating to the scangauge and then 15 sec more...
All in all happy for when I am towing and to prevent a serious overheating event due to a coolant issue or when the transmission is somehow pushed harder than I want. Now hope it will not drain the battery to much when parked say a week.
P.S. I did noticed on a test drive that the vehicle temp gauge gets to its normal point when the coolant gets to around 150 degr F and as it went up to 168 degr F (cool at the moment in the Houston area and the test drive was short) the dash needle did not move at all. I will watch this some more, however confirms the gauge is not lineair and not really helpful in many respects. I am also not aware whether a dash light will flash when the car is overheating, another thing Toyota should have looked at and include in another wise fantastic engineered and build vehicle...
Mount with modified magnetic attachment instead of dual sided tape. Provides some positon flexibility and removal when parked in the full sun when for example camping.
