Hello,

I’m using MelcoDiag with a known-good original ELM327 v1.4 USB interface (bough off of Amazon amazon.it/dp/B0F7S1W31Z). Communication with the bike works correctly, but MelcoDiag does not recognize the bike.

Bike: Ducati Streetfighter V4 S 2023 Euro 5
Detected bike code: 4F00
MelcoDiag message: “Bike not recognized: 4F00”
Estimated: Scrambler (bike=3)

Interface: ELM327 v1.4 USB
MelcoDiag version: 2.0.5.0
VIN: ZDM4F00*********
Communication seems stable

I have not attempted service reset or throttle/RBW procedures because even the mileage is not red correctly and I don't want to brick my ECU

Could anyone please confirm whether this ECU/model is supported, or whether the 4F00 bike code can be mapped correctly?

I'm pasting here diagnostic info/log (the complete VIN is masked):

Please note that I saved the debug log file before activating the license, of course I already activated the license but it didn't change anything.

Thanks.

thanks
it's patched you can redownload.
don't expect to see reliable data in the first menu , it's not coded yet ,
and it's safe do not worry

Thank you very much!
I just connected the bike but I was not able to reset the service light. I tried "Service reset", then "Annual service 0", then "Annual service 1" but none of these turned the service light off although the service date value is correctly set to today.

Thank you again for your support.
Do you think it'll be safe to also do TPS and APS resets?

I'd like to help if I can, I also have several developing tools (both hardware and software). Let me know how any of this might be helpful

euro 5 seems an other protocol , i'm just starting to dig into it with the help of cyclingdude723

I think so. Again let me know if you guys need any help. I don’t have a lot of experience in ecu mapping but I do have professional experience with canbus, firmware and software engineering
