ezCAN / Re: New feature requests for ezCAN ?
« Last post by SonicSparks91 on May 15, 2025, 12:37:57 PM »I've had an idea, though I'm not sure of the specifics when it comes to how BMW senses / sends data about heated seats. But i'd like the ability to be able to choose on the fly between Grips Only, Seat Only or a mix of the two rather than have them married together and having to plug into the bike to change your preference.
I unfortunately have a bike spec'd without OEM Heated Seats, and it would be extremely cost ineffective to replace the harness to unlock that functionality just for the ability to use the menu.
I was thinking since its already possible to read the Heated Grip setting via the CAN Bus, and use that setting for any 3rd Party Seat through EzCAN, would it be possible to-do the same with the heated seat menu on BMW bikes?
I am unsure how the bike would react if the menu option was enabled with no such harness being installed, but it might be possible since its not all handled on one controller. (It could be enabled on the Instrument Cluster for the menu, but not enabled on the Body Controller to prevent issues with Current Sensing / Short Circuit Sensing on a nonexistent harness) I imagine it passes messages over CANBUS about the rider's selection in the cluster over to the BCM to actually heat up the seat like it does with the grips.
For the record, I have a 2023 1250GS. Afaik thats how heated accessories are handled on my bike.
Hi SonicSparks91
The primary issue with enabling the heated seats handlebar button (not possible via the ezCAN or GS-911 just yet), would be that the bike then expects load on that connector. When it doesn't find it, you'll get a fault on your dash.
For independent control over 2 different heated items, you can follow the same steps as this gentleman below:

Note that even if you don't use 2 jackets, the same applies for a 2nd heated item setup, you can control one with grips and another as an aux light set.
Kind regards and safe travels

Thanks for the response!!
This is what I was afraid of, I wasn’t sure if the bike would complain if you only enabled the feature on one module and not the other, or if there was a potential way to disable the current sensing….
It’s a shame that ive already used all my outputs on my current EzCan, otherwise this wouldn’t be much of an issue as I’ll have to sacrifice a light set for independent control, or buy another one.
Now that I think about it, would it be possible to trigger EzCan / other accessories over BMW’s NAV Prep? I am currently waiting on Chigee’s AIO 6, im curious if you could have some sort of “switch screen” for this sort of thing given how it’s already able to read canbus data off the bike as well as interact with the wonder wheel. That, and they have accessories for CAN/LIN bus if Nav Prep isn’t an option.
Obviously would require some collaboration.
