Hello everyone, today I am trying to use the Melcolag program on my 2021 Multistrada 950s. I purchased, as described, the OBD2-USB Model ELM327 V1.5 (as shown in the attached photo) and the corresponding 6-pin Euro 5 adapter for the bike. I installed the ELM driver on the PC, and as shown in the attached screenshot of Windows 11 (Device Manager), it is correctly detected on COM3. The problem is that when I connect it to the bike and click on connect, After a short time, the error message appears as you can see in the photo, which is: "can't init ELM! check your setting COM number and COM Speed" Can you tell me what I need to do to make it work? Do I need to change the COM port speed on Windows, which I think is set to 9600 by default, or do you think the problem is something else? I've also read somewhere that someone recommends using ELM version 1.4 and NOT 1.5, is that correct? Would you advise me to return this one and buy a version 1.4? Thank you.

See my reply on previous page

Good evening, as I said, I am using the ELM 327. So, yes, I think I did. The COM port is correct, you then said that the COM speed doesn't matter as MelcoDiag changes it, so I didn't change it as I did a few days ago. I don't really get what you meant with the last sentence: "the cable is it an elm". Yes, it is, this is the product I purchased: https://it.aliexpress.com/item/10050090 ... 4itemAdapt
About the COM speed, back a few days ago you stated: "the com portspeed in device manager is over written by melcodiag , it's useless to change it there", ok, then do I need to change it somewhere else?

Yes you can change it in Melcodiag
Check the with the supplier what is the speed of the com port then report it in Melcodiag

Thanks for the answer. So, do I have to check the COM speed of my laptop? I can browse in device manager and adjust the speed, as reported in one of my first screenshot, is that the correct way to check the com speed? Is there any other way? I'm asking because if so I already matched the COM speed in device manager with the COM speed in Melcodiag (in the high left corner of the window). Anyway, later I'll try again and send you another debug report. Thanks

No , you need to find what the com speed of your cable then setup Melcodiag to match it

Ok, thanks. Are you referring to the ELM cable speed, correct? Not the 6-pin adapter, I guess.

Yes the com speed of the elm
