Technical ELM 327 Interface

To finish this post off, I do not suggest to buy this ELM:

The LED are facing at the bottom of the gearbox compartment and not visible, the software is crap, the bluetooth software dates 2007 and I did not get it working with any Android.

The following seems to be the best ELM interface:

Thanks for letting us know -- although I'm sorry your product testing was so frustrating.

Although I love my BlueDriver (referenced in my first post), I know that it's expensive... -- although they are constantly adding new features all the time... -- and it's maybe, therefore, not for most people. (I had a play with the live monitoring, the other day -- and it's getting better with each iteration. Once it's more European-focused, then, perhaps, it will make more sense as a package....)

Have you bought/are you buying that second interface? It looks extremely good value, when combined with MES or Torque.... Again, though, a set of cables seems to be the only option for reading airbag codes, etc..

Crying and swearing!

The second ELM (OBD) Interface did not work either!!

I bought the paid version of Torque App too for my smartphone and I can't have it working. The bluetooth adaptaer is correctly paired, the Android apps (about 8 different software) finds the HHOBD adapter, but then there is failure to connect and acquire data from the ECU. Torque OBD, for example, gives me a steady light for teh adaptor icon (=connect via BT) but a flashing car icone (= no ECU connection).

I am very sad because the applications look very nice and useful, but I can't get it working. I am clinging to the hope that it is some sort of setting. Anyone wit ha similar experience?

:-( :-( :-(

you don't have the problem detailed on the MES site regarding cheap Chinese ELM cables which are not wired properly might be why you can't get it to connect to the ECU properly

Oh gosh, this is something i can do!!! I will report it. I may also try and extend the led and make a power on/ off switch out of the fuse casing. Thank you very very much - big pincher of ale to you

Damn it: my resistors are 100Ohms as should be... however I realized that post is 117pages! I have to dig my answer very hard!

 

[PuntoHowTo]

I found mine had the correct value resistor but instead of being connected to ground two of the pins where commoned together with the resistor allowing the output to float so I simply removed the resistor and all was well

 

[Stephen505]

Here is my Interface. I am a bit skeptical to remove the risistors and will eave that as a last resort

Puzzled! I've tried alfaobd and it connected to ecu and worked well. So is the problem in the apps, and all the ones downloaded incl. Torque obd.. I would like to know which other apps maybe compatible with my interface since alfaobd is not free. I want an android app
