Defiantly the original ELM327 is used by KiWi products, also one could consider OBDLink product line that utilize some reliable alternative chip STN1110 compatible with the ELM327. Some info could be available at ELMElectronics page. Thanks!
Hello all.
I include myself on the list. I bought the Blue ELM327 V2.1 Bluetooth connector for my 2003 CR-V on the Dominican Republic.

In my case is not fare to say that the tool doesn't work at all. In fact it does connects to smartphone: LG G3 VS-985 and I'm even also capable to connect to some vehicles: 2011 Rav-4, 2013 Kia Rio, 2013 Kia K7 and other. But the one reason I need it no connect doesn't work: My CR-V.
In the link above you may find image of the item. Shortly I'll oist a picture of the chipset (IC).
I can confirm pins: 4,5,6,7,14,15,16.
I couldn't attach the pictures. Can't find the option.
Your Honda of 2003-model year could have no OBD-II support. This depends on target market, if it was assembled for USA it must have OBD-II for all madels starting 1996, but if for any other markets, it might have no OBD-II
The other possible reason could be that adapter supports not all OBD-II protocols.
Thanks!
Hello, what about the OBD2 in ebay at the range of 15-20USD? They usually say: KW902, KW903, and there are some cheap vGate. They are also wifi.
Like these:

http://www.ebay.com/ itm/152002399779
http://www.ebay.com/ itm/131665954601
Some of them have the same packaging but they seem different brand. Is it possible to have the
vgate or KW packaging and the PCB inside would be the cheapest Chinese ones?
Thank you
Unfortunately it's practically impossible to say "what's inside" without testing. All this product looks identically to iCar 2 - quite a stable solution from http://www.vgate.com.cn/en/ ... but unfortunate it's hard to say if they use the same chip and firmware as I've see that even brand VGate could be "shared" with different plants.
Thats what I thought... So any reliable e-shop to buy the vGate? Or any tested seller from ebay?
At the vGate page I do not see how I can buy directly from them.
Konnwei is something similar to vGate?
Hi,
I have just downloaded Car Doctor to try and retrieve the fault from my daughters Nissan Micra 03.
I am using a BT OBD connector that works fine on my 2012 Vauxhall Ampera but when I plug it into the Nissan it quickly flashes Green-Amber-Red and red stays solid.
Is this a car problem; as opposed to a BT device issue?
Thanks
Vince
There could be different issues, but the most possible is that Micra just have no OBD-II support in 2003. If your model was not assembled specially for the USA market, it rather have proprietary Consult protocol only in 2003. Thanks!
Hi. I have bought this one:

It has not arrived yet. When it does, I will connect it to some power supply to check if it will connect to a phone vie Bluetooth. And, if I can, will check for signal levels (voltages) of the output pins.
Untill then, can you tell me if any of you have this model (it is a no-name clone, but still), and did you had any problems with it?
Edit: Ops. When I was readin this topic on my phone, I did not see that there are more then 1 pages. OK, now after reading it all, I see that some of you did bought the same device. What I also noticed is that many of you where using it while driving the car, and it caused you problems. Well, this is not meant for that. You are only supposed to use it to read the codes, and then unplug it. Of course it will interfeir with the ECU while driving. Do not do it.
I have received the adapter. I have opened it up.
It uses NC7342-0 chip. It is probably a clone of the ON Semiconductor NCV7342: http://www.onsemi.com/pub_link/Collateral/NCV7342-D.PDF
It is a high speed low power CAN transceiver.
It is powered from the 70L05 linear voltage regulator (5V).
I did not connect it to the power supply yet, to see if it will connect to the phone via Bluetooth.
When I find time, I will see if I can also check the voltage levels of the output pins.
But, from what I am seeing, there is no reason to think that this device would damage the ECU. Unless the cloned chip has a "bug" in hardware that makes it output voltage spikes or something. But even then, the biggest voltage it could output would be the voltage it is supplied with - 5V.
The IC under the black "blob" is probably a microcontroller, to interface between CAN and the Bluetooth transceiver.
Well, even if it doesn't cause damage to ECU, with some of these adapters it is really hard even impossible to connect to ECU! I have tried on my Suzuki Swift Sport 2007 an OBD like the one you posted and even if it connects with the cell phone it will not connect to ECU. The same adapter has no trouble connecting on a Peugeot 207GTi though.
Some months ago I also was trying to connect on my Swift an other cheap OBD adapter (with black bigger plastic case, I do not know what was inside) and it connected after many many tries. Finally it was causing my check engine to light up for some random problem that was not actually there. Something about tachometer/dashboard I do not remember exactly the error code.
That is why I am thinking of buying something not as cheap as these crappy adapters and go for something at 15-20$. But I am also worried about getting a counterfeit of vGate because there are plenty of them on ebay with same casing and different branding. This is so confusing
There are also some adapters that might be almost good while working with single ECU and short commands, but cold fail to get reliable results for cars with 2 and more ECUs and "long" commands like VIN or DTC readings. One of this could have followingg MACs:
00:1D:A5:68:98:8A or 00:1D:A5:68:98:8C

ELM327 you can buy at Amazon.
