No, it doesn't allow. You can either use the mobile for other purposes or for Torque app. Multi-window is not possible.

The phone will detect it via the ECU and ignition is switched ON. Connect the reader and look at the LED lights on the reader it will be blinking (Power on).

I am sure about the OBD reader is ON always and it does take up a little power from the battery. The phone will detect it only via the ECU and when th eignition is ON.

Correct. It is one work at the time!

You'll ahve to buy another Android mobile special for the OBD if your that interested and can't live without music.

That is a bluetooth set that pairs will be infotainment system and the mobile will pair up with the OBD reader.

Good one buddy. If your frequently on the road then it will be useful but if parking over 2-3 hours then remove the reader from the port.

Agreed. Only generic codes are read and allowed access. For all manufacturer specific ones we have to contact the manufacturer. For Example Suzuki uses SDT (Suzuki Diagnostic Tool) which is not found on the Torque App.

You will have to keep two mobiles for this purpose. One for infotainment and one for OBD purpose.

The Torque App is for Android OS. If I ain't wrong.

Hey Anurag!

I meant - there is no equivalent great app on iOS app store like TorquePro on Android. DryIce suggested Rev for iPhone and I have to try it yet.

The point I made is - for ELM 347 to work, even before you go to relevant app (say fun2drive), the phone has to pair up with device. Once pairing done, then comes app and readings part. Pairing is done in every smartphone's settings section for bluetooth devices - just like you pair your handsfree equipments.

So, to pair up, you must be able to see the "pair-able" devices there first. For my iPhone4S, the OBD ELM chip didn't show up.

Now things to note here are -

• Handsfree uses a different profile to connect
• Other devices like OBD should have a different channels or protocols - may be direct port communication.
• Based on what OBD chip complies to, it will either show up in the settings ->Bluetooth section. It didn't show for me on one android device I tried from my stock. It was OS 2.2. So the bluetooth versions, OS versions may be playing role here part from hardware compatibilities if any.

There are very many of them available, so, yes, some of them don't have any visual indication. The only way to find out will be to use a good multi-meter (Fluke, Agilent etc., and not some cheap one) to note the current drawn from the battery with and without the dongle connected. If you like fiddling with some wires and plugs, get some wires, pins and sockets that fit into the OBD port and make a small jig where you can tap the VSUPPLY line through the multimeter probes

The phone pairs with both the Infotainment system (for calls, I assume) and with Torque/Torque-Pro for OBD info. I don't see the need for multi-window here!

The app calculates FE based on instantaneous fuel flow. When you take the foot off the A-pedal, DFCO (Deceleration Fuel Cut-Off) comes to play, which practically cuts off the fuel supply - only a very minimal amount of fuel will be pumped in. And, FE is calculated as distance covered with a unit amount of fuel. When you give some throttle input, the fuel flow increases and the FE calculation shows lower values.

You get full marks!

BT versions, OS versions all play a role. Do check the Torque App forums for more details:

Thats a bummer then!

About the power part, I guess better to remove the adapter when parking overnight.

Yes, even I think it could be due to BT profiles or versions. But seriously, this is

Multiple device connection should be possible but there is a chance that older APIs (galaxy y has android 2.3) might not support it. Search for some apps in google play, you may find a solution. I think multiple devices should connect.

There you are! Hope there is a solution, else I will not give away my iPhone for this ELM tool!

iPhone's bluetooth connection is kind of worst(no offence). In earlier version it only showed iPhones in the pair list. Although it should have been improved by iOS7 but i still think it won't detect an chinese obd scanner(for security reasons maybe). An android phone is your answer. Maybe try a tablet. I have a nexus 7 which is use for nav+obd.

It draws roughly 130mA of current. If car won't be used for a week or so, then it should be removed. I've kept it in port for 2-3 days(with car not being used) and there was no problem.

Noobie problems

The phone managed to connect to both the headunit and the OBD.
I just needed to test it a little better.

[rikhav]

Hi all
Do these obd readers also show fuel level?

My petra fuel gauge was never perfect

I think it cant draw any power when the ignition switch is turned off. So leaving the device there won't be a problem. I have left my USB version there from a long time. The device powers up only when the car is in ON status with engine still off.

That parameter is supported by OBDII however the car must be OBD-II compliant and also it should support the PID. Not all cars support all PIDs. Hence, the information available to you will vary.

[sara.ramli]

I guess the question of whether the OBD device is 'always on' differs with each car, just like the cigar lighter socket. For example, in my Figo, both the cigar lighter socket and the OBD port are always on (going by the LEDs), even if the ignition is off.

Yes it typically uses Bluetooth SPP (Serial Port Profile)

Don't know about USB one but Bluetooth ones take power even when car is off. Mine has a LED which glows up when it's connected even when car is off.
The reason is scanner can be paired even when car is off so Bluetooth transceiver needs to get power from somewhere.

Yes Dashcommand is the app for iPhone, but it will require wifi OBD-II adapter which are slightly costly.
One way to still use Dascommand with Buetooth OBD is to install some cydia packages in jailbroken iphone. What this essentially does is it will make dascommand think that it is interfacing with a wifi IP, while in reality you will be interfacing with bluetooth adapter.

Detailed info is available on net, just google.

Haven't tested this as I haven't bought the adapter yet. Someone with a jailbroken iPhone running on iOS 6 can easily check and share the results and the best thing is, it is free (for testing purposes of course)

This is exactly what I wanted to convey. If the car will be parked for more than 2 hours it is better to remove it as it will keep drawing battery power.

I tried to pair the bluetooth HU (friends car) and bluetooth of my OBD reader in his car and both worked flawlessly.

The Fuel % is picked up from the vehicle profile and calculates the distance to empty, instantaneous fuel. All these ain't that accurate as you have to enter the Total Weight of the car (fuel + drivers weight + car weight + accessories).

As you can see this image of the OBD II reader, the 'Power' and 'OBD' light keep glowing and blinking continuously in my car even when the key is not present in the key hole. I repeat, the Pin No,: 16 is connected to the battery that draws small amount of power. As stated by 'Skyfire' - 130mA.

Exactly the PID and ECU must give the OBD reader that sensor value to get displayed on your mobile.

For iOS with bluetooth issues and folks who are already using bluetooth for infotainment, can buy ELM37 with WiFi.

WiFi ELM327 can connect to same apps like Torque. They are little expensive but solves all the hurdles.

They are available on ebay, just search for WIFI ELM327.

ALL OBD Readers are getting power even in OFF mode, however some good chips go in power saving mode when not used for prolonged periods.

Some apps allows custom-PIDs to be added. You can find out what is the PID and add it in the display. So not only Fuel Level but other information which isnt displayed can be seen.

Here is an app which says it can connect to multiple devices simultaneously:

Torque Pro App does allow the addition of custom PID's.

How can we know the PID and how to add?

[mroptimist]

A noob question.

Was planning to buy an OBD adapter for my Innova V Diesel (2013). Is OBD port in Innova OBD-II compliant?

Thanks.
