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?
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
