I want to monitor some of my engine parameters, coolant temp in particular, on my Apple iPhone. Which of the Bluetooth/WiFi OBD devices should I get, and what application should I put on my phone?

 

GoPoint BT1 works fine. Their iPhone apps are pretty basic, but plenty of other apps that support the BT1.

 

+1 for the GoPoint BT1, I use it with my old iPhone 4 and iPad 2 using the Dash Command App.

Coolant temp is one of the DC's guages and can give a digital readout of the temp.

The Pioneer stereo headunit also has Dascommand as an app (I'll be getting it in the new year)

 

We sell a unit from ELM and will recommend DashCommand for Apple users, $35.

if you didn't want it on your phone all the time, I recommend the ultragauge or scan gauge, I have the ultragauge, and I love it, I have 6 parameters being scanned right now. Coolant temp, intake temp, boost, MAF sensor, Volts, throttle position
