hey all!

so i've done a few bits and pieces to my forester, and noticed that generally, when you add a new piece of hardware, that the car automatically adds extra functionaility elsewhere in the car. (for instance, if you add a GPS head unit from a wreckers yourself, it adds an extra couple of screens to the top screen, along with the speed limit on your speedo screen)

so i was wondering, surely we can add the dual mode X mode to our cars as well!

has anyone looked into this?


deep mud and snow mode appears to be SIMILAR to x-mode with TC off, but not quite. going from a video of the new outback in that mode going up a crossaxil hill, TC is still on, but allows a bit more wheel spin before it engages.

It may be a whole new ECM and other control module and not just as simple a swap as the radio head unit.

As X-Mode is handled by a multiple of controllers (engine, transmission, ABS, others?) it could be much more different....

Also, dual X-Mode seems to be on the Forester - notably the Sport and higher trim levels.

Of course, it could be like so many other items on the Forester - swapping out the basic part (the X-Mode control panel) may add that functionality to the Base and Premium units with "regular" X-Mode.

cant believe its been a full year since i last looked into this... but i guess thats covid for you.

so, i've been looking into CANBUS a little bit. planning on investigating the signals sent out by the dial on cars with single mode X mode, and comparing against those with dual mode X-mode.

as maybe i'll be able to add the dual mode X mode with my own buttons using a ESP32 and a SN65hvd230 or something along those lines

has anyone else looked into this at all?

so while this project kinda got dropped for a while, i spent another couple of hours on it today. (with this speed, maybe it'll be complete in 10 years haha)

i've got a device connected to the highspeed canbus, and i've already found the signals that show when the car is in x-mode, along with if the headlights are on etc.
i've got a feeling that the button for x-mode might be on a lower speed bus though, as when i sent these packets back onto the network, it didn't trigger the same result, so these addresses must be read only.

just need to work out where i can gain access to the lower speed bus.

any ideas on where i could splice into it, in a location that doesnt require taking apart of the dash to get to the back of the radio?

Would be interesting to hear if you make any progress on this. This would be an awesome mod if it can work.
