My bad interface looks like this. Not sure which version it is. So, do i need to remove R14 and solder 100 ohm resistor and 560pf capacitor like what 1st post did to cure CAN issue?

Hello Friends.

Lots of very interesting posts about interfaces which are not working correctly.

Can some one give us a link for a known good tested interface / supplier ?

Many Thanks

Darren

Another cheap 'Chinese clone', from eBay (UK seller, not china or HK), received 3 days ago.
It was sold as ELM 327 1.4 'with a genuine ELM chip'.
(For my personal information, I would really like to recognize a genuine ELM chip from a fake one)

Actually everything is working well FES wise, which makes me think it is actually an genuine ELM1.4
- NO communication problems, all ECU are recognized.(Airbag and steering not tested, pins 1-7-9 not soldered yet)
- NO problem to get access to service reset.
- NO installation problem. Just the drivers for FTDI USB to install.

On the last pic we can see the 100 Ohm resistors (R25/R26) for CAN H/L lines with associated capacitor (C14/C15)
Same combo shown by members in the last posts.

Hope it can help you to find the correct interface

Best regards

Hi,

it seems I do have this one interface. I did soldered additional pins. So, at this time I'm able to connect to engine ECU and ABS in my Alfa 147. Unfortunately I cannot connect to anything else.

This is result of Interface scan

Code: Select all

Scanning ...

ELM 327 interface found at port COM2, speed 38400bps
This interface is compatible with ELM 327 1.3! Should connect properly with all CAN modules.
Latency Too High!!!
