hello, I have this elm I don't have the resistor.
I still can't connect with the can network,
the pins of the can network counting from the left are exactly the number 6-7 the cleanest ones with the pond.
they start directly from the integrated vc1040, (clone of TJA1040) thank you in advance for your help.

I’ve posted this to add to the library of images in this thread highlighting the large number of different elm327 circuit board designs.
To get my elm327 Wi-fi interface to work with a yellow adapter cable I removed the 120ohm resistor R4 shown below bridging pins 6 and 7 on the adjacent MCP2551 chip. The Wi-fi board plugs into this one using the 4 pin plug at the top of the photo

Hello folks,
After reading through some of the posts, I decided to join in with my bit, hoping this is helpful to someone.
On my board it was R2 and you can see the position in the photos. I removed the resistor, it was also marked 121 on top.
Fixed everything and I was able to use multiecuscan with no issues and do proxy alignment. The first post on this thread has a very helpful diagram which helped me identify the chip that has 8 connections, of which connections 6 and 7 lead to the resistor I needed to remove and then onwards to connector 6 and 14 in the OBD plug.
I hope this helps and thank you all for your advice and experience.

Have a nice day! There would be a problem that multiecuscan has a timeout on the kkl vag-com interface. I get this error message when setting port.
"VagCom / KKL
Testing latency with 200 bytes of data ...
There was a timeout during the operation. "
port setting timeout set to speed 9600. Multiecscan throws the same error. Interface chip FTDI ft232rl drivers are installed correctly. Please help! Auto for which it would need Fiat Brava 1.6 16v 1998 year elm 327 not read, program 3.6 registered. Thank you for your help!
