Problem with OBDLink MX+, EX

Post by bshorey »

Hi All,

I'm new here, searched around and found some tips, but none of them solved my problem.

I've got a newly registered version of Multi ECU Scan. I tried using it with an OBDLink MX+, but MES wouldn't connect to it. After reading posts here it seemed that USB is better than Bluetooth, so I purchased an OBDLink EX, which arrived yesterday. I can't get that to work either.

Focusing on the EX (USB), I run MES and hit F9 to configure. I go to connections, then interfaces and scan interfaces. It correctly finds the EX. When I hit the test button all tests pass, and I get the message "This interface is compatible with ELM 327 1.4! Should connect properly with all CAN modules."

When I hit F10 to connect to the ECU, it fails with the message "ELM327->ECU Connection failed!".

I tried running the OBDWiz software that comes with the OBDLink readers and it works just fine. But MES fails as above.

Any suggestions? What am I doing wrong?

Thanks,

bs

No I did not. I'd have loved to try it on another computer but I'm not going to pay for additional licenses to troubleshoot their problems. Zero support, I've lost faith in these guys at this point, sorry to say.
