Car gauge OBD2 scanner nerd fun

How hot does the engine get especially when tracked? No idea! Without any gauges to tell me, I decided to get a OBD2 scanner and my old HTC phone to read out some temps to keep an eye on things.

Very happy with how it all works from the info I can read out to the refresh rate. Long term I'll either mount the phone in the car somewhere or get an Android head unit output this to.

Went with a used Scantool.net OBDLink MX from some guy in WA. Took almost 1.5 weeks to arrive by AustPost. It's so far it's almost a different country! And the bullet casing in the top right was in the box.... 

 
The OBD port is positioned in the foot well near the clutch. A small compact design means I won't hit it when I'm driving, or kick it getting in and out of the car.

The original OBDLink app that came with the scanner. Looks nice and is fairly customisable.

Torque app. Doesn't look as good but is more widely used judging by forums. A small tweak in adding the output parameters was required to get oil temp read outs. Definitely out an out-of-the-box solution by a long shot.


Need to think of a better place to mount this in the long run...

Borrowed one of these type of OBD2 scanners to test before I went the OBDLink MX but unfortunately it didn't work and threw a CEL. Helped me decide to go straight to the MX
