ah, ok so no easy software tweak. And not easy to reverse then. But good job!

It is kind of mixed bag side channel hardware/software hack. The HW is done by HARMAN Automotive.

For sure it is possible to officially program it via OTA and OBD/FDRS but doing so yourself is way beyond what I was willing to invest, if it is possible at all.

There are crypto signatures in the data, I'm actually impressed by the level of professionalism present in the system.

I read through this entire post and came up empty, other than one guy earlier who I saw in his list of modules had an HVAC one he could access.

When I look at the spreadsheet, I see there is an HVAC module with a lot of different parameters that can be adjusted. But when I open FORScan on my car I only have these modules, no HVAC module. Is there something I am missing?

May I ask what type of OBD dongle you are using?
I can imagine that yours may be one of those that show issues with the different CAN network protocols.

Yes I’m using a Tactrix Openport 2 adapter as I had one for my Mercedes. I didn’t think it was a cable issue since it picked up some of the modules

Doing some googling now I see others have issues, I’ll pick up a new cable. Thanks for the memory jog!
