Most are the same though the device numbering is different and the lighting and seat control messages on my Puma are very different (though oddly horn is the same) which probably reflects the fact that they were testing on a Permobil!
More to come as I get time to dig deeper...

@Irving
Hey I'm new here and definitely not a network expert. Can you talk about the bus...what version? I've heard of 3...and there may be more.
CAN 2.0A 11 byte messages identification (standard), 125 kbs
CAN 2.0B 29 bit message identification (extended), 1 Mbs
CAN FD Flexible Data Rate, 10 Mbs
I'm still trying to figure out who is who on here. Are you involved with the work on github? You wrote software to scan/monitor the bus and collect data into readable frames? I didn't know there were more than a couple frame types/sizes.

I can now read the parameter pages, including the OEM settings, without a programmer, through my own windows app. Slowly working out what bytes represent a specific parameter and I already know which bytes represent the holy grail of the hidden acceleration etc. settings Won't be too long before I can change them!

Ideas anyone?
when you load an OEM file on the laptop it complains the parameter file is out of date, but carries on and opens it,
thats a very good Q and one I've yet to find an answer to. According to PGDT the generic will leave the custom bits alone; you can still edit the file but you won't see/edit the custom bits. How they achieve this isn't clear, I'd expected the custom bits to be in a separate memory block but the Sunrise voltage setting for example, which is a custom bit, isn't... I need to do a bit more digging.Burgerman wrote:Not sure I have time at the moment but send me anyway!

Does it matter which version? The sunrise one has stuff the generic doesent for e.g.

Irving wrote:More progress to report. I now can write parameters back to the various modules though it isn't a simple process, it's more a block transfer of data. There does seem to be a way to change parameters individually but I'm not confident I've got that safe yet. I am just needing to research it more, don't want to brick anything!
I've also nearly completed mapping out the R-Net file structure and the block structure of the file neatly maps onto the parameter pages in the controller(s). In fact the file is a snapshot of the system memory! There are hundreds of not thousands of parameters and I've only identified about 50 so far.
So now I need some volunteers to help map the remaining parameters. You don't need to have a programmer, this is all offline from the chair. All you do need is a copy of the OEM programming software and the master file from a chair, either yours, mine or someone elses. I've written a little bit of software to read in an R-Net file and monitor it for changes when you use the OEM software to change something. All it needs is a methodical approach to change each parameter in turn and let my software record what changes. Tedious but three or four people working on different pages of the r-net file will map the whole thing in a few days.. Any takers?
