Torque Lite
 

I am using this for monitoring engine temp's but can't figure out how to make it give a warning for high temps, has anybody achieved this. I can see real time temps with it connected but I don't want to look at it all the time but want a warning signal lets say if the engine hits 220.

I haven't used Torque Lite for at least a few years as I got the Full Version.
Maybe that's the difference? The warnings and such are not available in the free version? Maybe read the disclosures inside the App Info about what's different between Lite and Full versions.

The Paid Version is only like $6 or something if I remember (my full version came free with the Bluetooth Dongle I bought), and it does add some good stuff. I have my alerts turned on.
