What OBD-II display do you use?

[Matt Hixson]

I've used a ScanGauge II on my Hummer for a long time, but am developing my own based on the Raspberry Pi platform. More info about it on my website.

I'd love to know what other people are using and what you like/dislike/wish it had.

I have used these for years on my cars, and helping others out. Though 99% of the use I have is simply diagnostic in nature. I like to monitor things from time to time, as a checkup, and if codes pop... boom goes the OBDII tool.

I have considered adding a full-time gauge cluster using this port... but never really took the time to do so, as I never really felt it was a NEED more of a fun gadget than anything.

These are a MUST HAVE for any 'modern' car in my mind though. Without a code reader... you are out of luck half the time when something goes wrong. Everyone should spend the 20-30 bucks to keep one on hand for sure. Why would you NOT have this available to you.

My thoughts exactly. I also like to monitor stats for things that I don't have stock dash gauges for, such as turbo pressure and transmission temp.

These are also great for the time and again event like a heavy tow or harsh conditions. I like to monitor transmission temps, oil temps, etc... it's a great way to know for sure how hard the vehicle is being pushed. Once you start overheating your fluids... you know you are making the part unhappy.

I also use this to gauge how well an engine is running... for instance a friend's car with unknown issues, or buying a used car.

I use elm 327 and torque pro in both rigs for monitoring and quick diagnosing. For other stuff, I use diag fca laptop software.

I use BlueDriver (BlueDriver Scan Tool | BlueDriver). I mostly use it as a code reader, but it will do live data and mode 6 as well.

Kenwood DX radio has it built in. Works great.

I have the ScanGauge II in my truck as well. I use features that my 02 didn't have by default such as MPG, Ave MPG, Air Intake Temp, HP, and scanning error for codes, etc. I also have a WiFi enabled OBD device that connects to my OBD Fusion app on my iPhone. This opens up a whole new world of features, e.g. boost, load, etc.

For JK/JKU I run OBD JScan with a VeePeak dongle. It allows adjustment of all of the CanBus functions and all dealer options. You can also run it as "live" data to monitor current conditions. I use it when towing or high elevation for oil, engine and trans temps primarily. Free download at Play Store/iTunes to see what all it is capable of.

ScanGauge II. Few different phone apps that use BT. A must have is a code reader that can reset codes.

I usually use my iPad mini or an Android, with my Bluetooth OBDII scanner hook up.

 

[KonzaLander]

I use an OBDLX Bluetooth module and Torque Pro on my Android head unit.


My biggest complaint is the speediness of the connection. In the above image Torque started trying to connect to the ECU once it was the vehicle was started, but you can see it did not connect until the coolant temperature was already at 116 degrees.

I use the OBD Link MX+ and display it from my iPhone, one of the best devices I have for my truck

I have about the same system in my Truck. It's a 97 so it doesn't have many options for OBDII but I can monitor my coolant and intake temperature.

I am looking at the Scan 2 for my 5th gen 4runner to monitor the transmission temp, any ideas, suggestions or other recommendations? Thanks!

I use the Torque app, they have just about every PID sensor you could possibly need, for some that arent there you can input custom ones. Works with any bluetooth OBD-II adapter.

I have the OBDLink referenced above. My primary motivation was to monitor tire pressures when airing down for offroading. It’s a big pain to get the phone out and get everything connected. It works pretty well. However, I think I’d prefer a dedicated gauge, like the Scangauge, that would just be on all the time. Then you don’t have to mess with the phone and the quirks that can come with that. I don’t use what I have as much as I should simply because I don’t wanna fool with it.

That was my concern as well, so I went with the Scan 2 with gauge, I just need to monitor the transmission and engine temps, beyond that I have old school stuff and it is not a race car so the rest is cute but not useful to me right now. I of course say that now.. once I have it installed I am sure I will be like, oh wish I had… then I will buy a dedicated phone to run the dedicated app…

Second question: which sensors do you monitor as a cluster during:

(1) on-road driving
(2) off-road driving
(3) towing
