I have a mini bluetooth elm327 v2.1 obd2 adapter. I plugged it in my mazda 3 spirit 2.0L model.
I am using torque pro, and did not encounter any problem.
Is there any chance that some problem or damage is possible ?
Different programs might use different subset of ELM327 and OBD-II commands, even the same program could use different commands with various use-case scenarios. Some risk remains as one does not exactly knows the exact "dangerous" commands (generating failed signals with bad adapters) and cases when it could be send from the program.
Is there any specific proof that the elm327 v2.1 caused any damage ?
Do you know for sure that there is some hardware bug in this adapter ?
Just blaming this adapter that it is bad is not an acceptable statement !!!
First we are not talking about original elmelectronics.com products!!! No restrictions about original ELM327 with any version of firmware!!! All others is about some clones marked as v 2.1 and just a statistical observations from our users no blaming that's up to you use any of them. Even more we try to bypass known issues within our software. Have a good luck!
just got my Vgate (blue tooth) OBD Scan tool I have paired it to my sansung 4s phone.when i connect to app on phone iit get no reading. i only get power light on the scan tool never the OBD or pc light.is it the scan tool app or some other problem ?
Switch off then on bluetooth support in phone, plug off then on adapter.turn on debug logging on page Menu-Configuration-Logging, try to connect then send log from the Menu-Configuration-Logging with issue description, comments, adapter and car details including year. Thanks!
Attention "bad" adapters!
We faced the problem, that some adapters (often Chinese one), can’t connect to the smartphone.
The reason is its MAC address (one can see it while connecting and searching for the device, so the adapter’s name will be detected and its MAC address).
If the MAC address of your adapter starts with the numbers 66:35:56: ... (for example, 66: 35: 56: 78: 90: AB) - be prepared that this adapter will fail to connect, and what's more, they can cause problems with your car.
As well, there are problems with Chinese adapters marked ELM327 v2.1.
We ask to share with us the names, photos, links to these adapters to make a "black list" of such devices.
Hi guys,
please make sure that your OBD clone is not this because seems to have the same problem fails to connect to the car with: 66:35:56:78:90:AB not found!
AVOID THIS ONE TOO: follow link
Hi all,
I've bought a cheap chinese ELM327 v2.1 adapter.
I was trying it using Torque Pro and after 10 minutes on the road that car displayed several error messages (electric break fault, wrong oil level, etc), i stopped the car and turned it off, turned it on and it was saying "Electrical malfunction" or something like that. At this point the car wouldn't start. I disconnected the device, tried a few more times and at some point, everything went back to normal, and the car started and have not displayed any more error messages.
So this adapters CAN induce damage to cars.
The car is a 2004 Renault Scenic 1.5 Diesel.
The adapter as a different mac address of the ones mentioned on this thread: 88:18:56:68:98:EB
I've made two logs:

http://pastebin.com/ pjraAjq2
After connect OBD Car Doctor free was giving me the information in "General Information" that it was a 2.1 device.
What do you think?
You are right device with MAC range 88:18:56:... absolutely the same as 66:18:56... from the same manufacturer and only difference is color of the cover case. So the device might at some cases generate unsafe electrical signals dangerous for the ECU and electric subsystems of the car. So we can't recommend using of this adapter. It's better to change adapter for some other marked as 1.5... or brand devices with original ELM327 (with any version).
I tried this tool:
http://www.dx.com/p/ elm327-wireless-obd-scan-tool-112586
It is advertised as ELM327 v1.5, has MAC 66:35:56:...
And I'm able to pair the device. but that's it. Car still starts.
same problems as vguset but with fiat punto 1.9 jtd
when elm 2.1 is connected, can't start engine , clocl was reseted and all indicators show zero even with engine on.
after disconneceting elm, i have check engine lamp on
Hello.. I have an issue with 2.1 version.. I have ELMs one chines one from eBay they both answers with ? on command such like this ATCRA700.
So they don't know the command CRA for some reason
Who may know is that suppost to be this way? Maybe they change some parameter I don't know about. I google it can't find.
Pls can you guys send this command (ATCRA700) to your ELM to check what youve got for answer a ? or OK.
Thanks appreciate.
In reality there are some differences in firmware of clones marked as 2.1 but all of them looks like strongly limited or very old version of original ELM327 firmware. So a lot of AT commands are not supported. No problems with AT CRA xxx on original ELM, standard answer is OK
Bought two from eBay, the first partially worked, second arrived today, this one solid black car a rather than clear blue mini. Both with same mac as in this thread 65 v2.1 . Torque pro connects it connects to car can see some real-time data ie throttle position but reports no fault codes at all. I know there are through more reputable diagnostics.
How about instead of listing just dodgy adapters which is good someone posts a link to a reasonably priced reliable adapter known to work well.
