I'm looking at the OpenXC Ford Vehicle Compability spreedsheet. Is there some one of Ford firmware that is compatible for a Ford S Max 20011 model?

Hi Ola,

At a first glance, the Type 2 firmware would be the best bet for your application. If that does not work then I suggest Type 1. I would test myself, but it's a bit difficult finding an S-Max here in Michigan... :)

Let me know if those work or not. We can investigate further if need be.

No, there isn't yet. The current European Mondeo, S-Max and Galaxy would be compatible among each other, but they hardly share any OpenXC relevant CAN messages with the vehicles currently on the list. Note that Type 3 refers to the new Mondeo that will be introduced in Europe only later this year, not to the current one.

Hi Zac.

I would like to start developing (firmware) for a SMax and would like to ask the first steps to do it.
Do you know anyone who can help me with the first steps?

Thank you,
Alex

Hi Alex,

I have no experience in writing OpenXC firmware but I guess once you can decode the raw CAN bus messages then you only put the mappings (correct value translations) into the firmware. You simply need to get the data for the "dashboard values" (https://github.com/openxc/openxc-message-format) from CAN bus. So decoding the CAN IDs and its values it a crucial step here and will involve pure reverse engineering. You can use some other device to decode the values (ELM 327, OBDLink devices etc.) - they may be quite powerful for reverse engineering. An example of the process may be here: http://www.electronicsworkshop.eu/FordMondeoCANhacking Hope that the CAN data bytes of messages are not encrypted somehow - on the older cars I guess they usually were not.

There may also be a higher-level SW that is helpful - like this CAN Monitor Pro (https://www.youtube.com/watch?v=Q0i_Z3Vzi7U) where you can reverse engineer the data easier. However, I guess quite a lot of effort will be needed to get the complete dashboard values. However, Id love to see someone doing that...
