OBD II access on Ducati Scrambler for data logging

[Paimo]

Hi everyone, I am just wondering if the Ducati Scrambler has an OBD II connector, and where it might be found. I'm considering using the built-in USB power to hook up a Raspberry Pi for logging ride data

The Ducati Scrambler doesn't come with the usual 16-pin OBD II port. Instead, it features a 3-pin "SICMA" connector, which you typically find under the seat or close to the battery/ECU. To connect it to a Raspberry Pi for logging purposes, you'll need an adapter. I've noticed some folks using software like jpdiag for ECU communication. What model year is your Scrambler?

nope, the Ducati Scrambler (like most bikes) doesn't have a standard OBD-II connector like a car. They use their own proprietary diagnostic port. For the Scrambler, it's usually a 4pin connector, often tucked under the seat or sometimes near the battery.
You can definitely use it for data logging, but you'll need a specific adapter cable that goes from the Ducati 4pin to an OBDII style port (usually 16pin), and then an OBDII dongle (like an ELM327) that can read the bike's specific protocols. The Raspberry Pi should have no problem with the USB power, assuming it's a lower-power model like a Pi Zero W

Mine's a 2020 Icon, I'll look into the SICMA adapter and jpdiag, but have you had any luck logging data this way, or is there another tool you recommend?

That helps a lot, thanks! I've got a Pi Zero W ready. Do you know if the ELM327 handles Ducati protocols well, or is there a specific dongle you'd recommend for better compatibility?
