Does anyone use OBD Gauge for monitoring RPM and water temperature?

I use a ScanGauge. It works well, and uses very little sleep power when the car is off.

Water temperature is a number I usually have on the display. RPM isn't. I had it displayed for a while out of curiosity when I first got the ScanGauge, but it's just not that interesting in a Prius; the engine is always being managed by the car, it does what it does, and after that initial curiosity, the urge to hover and second-guess it sort of fades.

 

On my 2026 LE, I use the OBD Fusion or Car Scanner app, both of which display on the infotainment screen via CarPlay.

 

P10 for years monitoring engine temp and aux battery. Has user set alarm limits.

 

Interesting! Does a 2026 LE have an engine oil temperature sensor, then?

I wonder why it would be that much cooler than the coolant.

 

I use a V-gate vLinker FS Bluetooth OBD2 Scanner with the Torque Pro and AATorque app on Android Auto.
This allows you to display lots of parameters on the central display with Android Auto including, RPM, coolant temp, oil temp, Volts, SOC, speed, LTFT1, AFR, MAF, timing Adv, etc...
There are hundreds of parameters displayable on up to 10 panels with dial or digital display.
I wouldn't do without it anymore, since I use it continuously.

 

I've been in iPhone world for a relatively short time, but I've got no experience with Android Auto.

Car Scanner has a profile for Gen5 "Primes" that provides hybrid-type data.
No dials on CarPlay.

 

Sweet!

 

there. What you meant by "Car Scanner has a profile for Gen5 "Primes" that provides hybrid-type data.", is that the app name or the just general car scanner OBD device? I looking for more MPG data, I used to track my mileage and mpg, but now with Hybrid, I havn't figure out best way to calculate MPG per Electric or per Gas. Any info is helpful, Thanks

 

Car scanner is an app. It has a prime profile that can be used.

I do not have a prime. Some one with a prime aka phev will have to help you.

Perhaps @gokahn can chime in?

 

I've had a Scan Gauge, it's about $150, but with the Prius phone apps and a Bluetooth OBD dongle it's more affordable. I have RPM to watch going up hills. Coolant temp, intake air temp
