One uobd2.net user buy one MINI ELM327 Interface Viecar 2.0 for Android/Window, and yesterday he shared how and what this tool can do, he think this tool is cheap and working, his professional experience and objective option will do a favor to those who never use this tool. Therefore I would like to quote his original post in the following parts.
I got a new toy for christmas (from me to me) and have been playing with it quite a bit lately.
First, I ordered an ODB2 to Bluetooth adapter and hooked it up. Simply pair it to your Android device (apple is more complicated) like any other Bluetooth device. I did have to restart my phone before it’d pair but my tablet paired right away. This is the one I bought:
the interface is highly customizable and will show TONS of parameters with the ISF ECU. I have gauges showing 0-60, 1/4 mile, speed (from ECU or GPS), Engine speed, torque, horsepower, afm, voltages, etc. It’ll also allow you to see and clear codes off the ECU. That alone was my excuse to buy it to the wife! There are different themes to the gauges, with infinite gauge layouts you can use.
I’d highly recommend this to anyone with an extra $15 lying around. The app is $4.99 and the device is $9.99.It’s a great cheap monitoring tool that I’m looking forward to using in autocross videos. It’ll do logging and everything that the more expensive tools will do for much less money. The options I mentioned are just a few of the monitor able parameters of the ECU. I’m in no way affiliated with this but I’m having a blast trying out this technology!
So far the best I’ve run is a 5.0 0-60 (tire spin in the cold).

This PDF step-by-step show you how to use MINI ELM327 Interface Viecar 2.0 OBD2 Bluetooth for Android/Window:
I got myself an Elm327 V1.5 but I found that it will not work on J1850 VPW J1850 PWM protocol especial for most Fords. But it did work like a charm on cars.
My idea came from a post in mondeoklubpolska.pl/ forum. Thanks Atom from Poland. I got the post translated into English, then I tried it out on my 2001 MK3 duratec 1.8 and it works like a charm. So I make my new version.
I have to confirm that the method only fits for elm327 V1.5 as mine and I have no responsibility if your elm327 is blow up or broken.
Solder iron with very small bit and solder
About 10 mm of insulated small-gauge wire
Then do as follows:
1) Peel off the cover of the elm327 main unit and remove the four screws by using screw driver, take these out and set the box apart.
2) Check the elm327 inside is like this
3) You will notice that there is a PCB tack running between T5 and T2 there. Hook up a multimeter to check the continuity between the emitter of T5 and the emitter of T2 (on the side with two legs). If there is continuity, you should use the knife to cut between T2 and T5 as shown in red below.
4) Check between the emitters of T5 and T2 to make sure there is no continuity any more.
5) Solder a short length of wire between the emitter of T5 and the emitter of T1 or Pin1 of the output connector. Be carful not to apply too much heat to T5 and T1.
6) Again use the multimeter to test the continuity between T5 and Pin1 output connector. Ensure there is stable continuity.
7) Reassemble the elm327 main unit and try to test on J1850 PWM system.
The job is done.
I got a mini Bluetooth elm327 OBD2 adapter for my Toyota Matrix 2005. I figured out that the tip is to get a mini version, in that case you can stock it in without having to loosen the bolts. Many software available for this mini scanner, but I decided to use it with Torque, because the great app is free. I have Torque installed on my Samsung NOTE 2. My mini Viecar adapter can be applied on Android and windows as well. But I prefer to hook it up to work via Bluetooth on my Phone.
I first connected the mini elm327 scan tool into the diagnostic socket, downloaded Torque software on Google Play Center and installed the free software to my phone. Searching Viecar2.0 Bluetooth after open Bluetooth setting. Than enter the pair code 0000.But my Samsung said “Paired but not connected”. I have to refer the user menu and figured out where the problem lies. Then I went into the configuration of Torque as follows: when you first open Torque, press the parameters icon, then press “Settings” and finally select“OBD2 Adapter Settings”, “Choose Bluetooth Type” and “Viecar V2.0”. I activated the “Faster communication” parameter and since then has worked well.
I suppose different elm327 adapters have different pair code. But in order to avoid my mistake, make sure do some basic setting (Choose connection type and Bluetooth connection device etc).
I have tried several cars, 2004 Toyota Caldina GT-Four, 2002 Toyota IST(also called 2005 Scion Xa), 2003 Nissan Sunny B15 etc. The Viecar adapter enabled me to get the fault codes from the plug successfully.I have tried both with the ignition on and the engine running. I have also tried disabling the elm327 automotive adjust and with try faster communication. Nice display parameters, cruse control, door remote etc. I gave the OBD2 scanner 5 stars because I feel $10 for the device is great deal. Just think about the price and you wont be disappointed.
