I'm using the free version of "Torque".
If there's something better or easier to pair and use, I'd be happy to change though.

I use an ELm with wireless. Connection for me involved a 2stage process, first make a connection between the phone and the ELM, then I had to set some parameters in torque. Might be worthwhile looking for some detailed install instruction on google.

Bluetooth can be a bit temperamental, so get your S3 to forget the elm and start again.

My connection wouldn't work properly until I started te engine.

Here is a link to the connecting page on the torque WIki

Getting Started - Torque OBD2 Wiki

You will need to know the pairing code for your adapter to pair successfully, if you got a CD with it, the code may be on it somewhere. Usual ones are 0000 and 1234, I have seen 6789 also

good luck

Re: OBDII wifi dongle and Ipad app

I have been using the ELM WiFi device with my mini iPad running "Dash Command" for most of the last 2,000 klms of towing.
I have not had a single issue with this setup. It works very well indeed, and connects straight away, every time.

At the moment I am still experimenting on what to display when driving, currently watching Boost, Coolant Temp, and EGT, still learning as I go but great to have that info available. There is a huge range of info to choose- I would love to find out if any DPF info is available, but yet to find that in the mountains of info listed.
(I also have a map App running and "four finger swipe" between maps and Dash Command as required.)
It is interesting with the coolant that the temp goes straight to about 97C which is obviously where the thermostat starts to open. The hottest I have seen on a hill is 107C -with a lot of analogue gauge movement towards H- but obviously not an issue. 107C is waaay below boiling point for pressurised coolant. (Most cars have "dumbed down" gauges which don't move for such temp ranges.)

The only downside to the ELM WiFi is that it is live 24/7, ignition on or off, so would cause perhaps significant battery dischage, which might be an issue if not driven daily.
I don't know how much power it uses, but will connect a clamp meter at some stage to find out.

I got mine working too now thanks to advice from contributors on here. Interestingly, I tried it on my BA Falcon ute, and can't get a voltage reading - can't figure that one out!
What is EGT called on your list? I can't find it on mine, but maybe that's because I bought a $13 dongle on ebay.
If you get a chance to work out power consumption it would be good to know, but I bet it's negligible. Anyway not difficult to remove the dongle when not in use. The hard bit is remembering!

You can buy ones with On/Off switches. There is a new one coming that will turn itself on & off - ScanTool.net LLC - OBDLink MX Scan Tool | OBD Interface | App Accelerator - ScanTool.net

Re: OBDII wifi dongle and Ipad app

Thanks David, for the feedback on your setup. As Snuke noted, I've also seen ads for ELM27 wifi dongles that switch on/off with the ignition. They are expensive little critters though compared to your powered on all the time unit, but that's all relative.
Enjoy the journey while you are tweaking.

$13 is damn good if it works!

The EGT that I found in the DashCommand gauge edit section is called :
SAE.CATEMP11


I have no idea exactly where it is measured, but somewhere in the pipe near DPF, and downstream of the turbo I would guess. I don't of course know what temps are acceptable, but it still gives me a good idea when climbing hills etc if a gear and rev change lowers or raises EGT, thus enabling me to minimise it where possible.


(Not all the listed functions work, for example two I've found are voltage and fuel rail pressure. I'm sure there are a lot more.)

PS. & OT. Has anybody looked at fitting a "catch can"? (I know there is a separate thread somewhere.) I pulled the pipe off my PCV pipe and there is a lot of oil in it. That can't be good for the turbo, unless maybe they are designed to handle that??? I'd love to speak to a turbo specialist for an opinion.

Yes it works now that I've figured it out. I'm not sure though whether the actual display content (e.g. EGT) is the dongle, or the app that you use with it.
I would like to be able to display EGT but it definitely doesn't show on my list. I am using "Torque" free version.
It will display voltage on the Jeep but not on a BA Falcon. Obviously some incompatibility there.
Can someone advise whether I need to change apps (and which one) to get EGT, or whether it's down to my $13 dongle.

Re: OBDII wifi dongle and Ipad app

There is no EGT sensor that currently can be viewable by these dongles.

Why do you say that?

It works for me!
I was using it all day yesterday climbing some very steep grades up and over the local mountain range. Admittedly I don't know exactly where it is measured, but it is somewhere in the exhaust and/or DPF.

During DPF Regen the Cat Temp (also visible) and EGT went to 1200 F for several minutes.

Anyone towing should invest in a Torque App setup. I have $30 total invested.

I found this on a USA thread on this forum - haven't been able to get mine working yet though - the gauges are there, but no readings. I have an MY13, so maybe the OBDII output is different.

The name of the reading that Futuresystem found sounds like it could be "Cat temp"?
