Just thought I would throw this out there. I ordered a Bluetooth obd2 reader and bought torque pro for my phone. It works great. I love knowing my coolant temp, o2 sensor temp and all these little things about my fit. The sensor cost me 11 dollars and the app was 5.

 

I did the same thing a few months back. Its kind of awesome just to watch all the sensor data in real time. Its worked in everything I've tried it in. Totally worth the 11 bucks for it.

 

what exact Bluetooth obd2 reader did you buy? any specific brand?

I bought this one. Shipping takes forever, but the pairing process once I got it took less than 30 seconds.

Anyone know of a cheap iphone version of this?

 

Haven't been able to find one. My buddy wants one but has an iPhone

 

Looks like non jailbroken iphone users have to get the wifi version as Apple says nay-no to their Bluetooth stack. Why do I have a iphone again?.......

 

Because, you are you.

 

thats cool that you can take the gauge with you since it is your phone.

ive heard of people's cars getting broken into for their scangauge... lol

 

I have Torque Pro as well, love fooling around with it to see what my Fit's parameters are doing. One which looks a bit scary, which I was viewing today, is the Catalyst Temp reading. At idle after warmup and driving a little, I'm seeing temps at 900-1000F, and it will easily reach over 1400F under acceleration. Wondering if the fuel trims are a bit rich here? Might explain my less than spectacular city fuel economy. Best I get is 29 on the MM, which in real numbers is more like 27 or so. But that cat temp really got my attn. That thing must be glowing orange if that number is for real!

 

Mine gets that hot and I get 38mpg on the highway with no ac
