FAULTY ELM 327 INTERFACES DE-MYSTIFIED (READ HERE)

[kk159]

Hello guys,

I'm new here and I already red whole thread. You are doing great job! Unfortunately I didn’t' find my OBD device (ELM327 Bluetooth mini) modification.
So, I'd like to mode my ELM327 because it won’t work with my Alfa 159 and ECUScan 3.6.2.

I'm receiving:

WARNING: This interface is not compatible with ELM 327 1.3! Will not connect to any CAN module.

I’ll be grateful to you if you can help me with modification? Here are pictures of my device and if needed I can unsolder upper circlet board to get pictures from inside.
Thx in advanced for your help.

Hello

But your interface has already been repeatedly described here !!

The Interface v2.1 not operate with MES or AlfaOBD
Unfortunately, I do not know any of the current to be purchased Mini ELMs the
are kopatibel with MES.

But I purchased it from ebay as "Mini ELM327 V1.5 OBD2"...I'm not so deep in this topic to see differences, but probably you see on pictures that I received newer version; Am I right?

Hello Mitix

Unfortunately, your image is not very clear

But if I am right should be on the back of the bridge resistor R2.

And make time a screen from the MES Interface Test, and please put the one here
let's see if MES can work with this EL
Because now there are many interface that can no longer work with MES or AlfaOBD

Hello KK159

Unfortunately, the traders also do not know what software was burned to the PIC.
The dealer is also hereinafter referred to as the manufacturer's specifications

I also bought Interface V1.5 but get the version v2.1
And these have given back and get my money back.
