Anyone figured out where to get the CAN bus data for AIM/etc. data loggers?

What did you plug into? OBD-II port?

Yes. The CAN bus is there, but we just need to use SSM to interact with it which is... annoying at best.

Like this, except I don't have an AP to let me sniff the data...

This might be an interesting lead, but my gut feeling is that plugging in somewhere other than the OBD-II port and listening to data already on the CAN bus will yield better results.
That's definitely something I'll try once I get my 2022.

Yeah, that would definitely be easier and *way* less annoying. When I have time, I'll try to find the right connector to plug into the active sound computer. I'm super busy with work & holiday stuff so not happening soon for me sadly.

Is there any info on the connector, pinout, etc.? Any part numbers?

How is this? Don't know the plug number.

Awesome, thanks!
Wiring diagrams like this usually have a separate image explaining what connector it is, is there anything on this page or earlier/later page explaining what "i121" is?

It's basically just a rectangular looking plug. I'll add the image to the other post later today, when I can get to the file.

Where did you get the wiring details? I'd love to see the full electrical diagram for the gen 2 cars.

I got RPM, TPS, brake pressure, and steering wheel angle from the ASC connector today

I'll put together a google sheet with the data when I get a chance. I have a ton more CAN data to test and see what does what, it's going to take me a while to get much more data, I don't have very much time to dedicate to this.


A friend of mine is looking into what connectors to use to make a T harness to keep ASC or just plug directly into the ASC cable. I did a little hacky thing to test, would not recommend haha.

Yeeeees!

Have you tried all CAN IDs from this page?
https://github.com/timurrrr/RaceChro...can_db/ft86.md

Can you please document which ones work and more importantly which ones DON'T work?
If you're familiar with how to work with GitHub, feel free to send me a pull request to add a ft86_gen2.md page to the same directory with whatever details you find.

Very much interested in that too! Is there ACC power pin in that connector?

Look at the diagram I posted above. IG = ACC

[DocWalt]

*none* of the old CAN IDs work. I'll document things on a spreadsheet, feel free to move things to your page, I have no issues with that at all

There seems to be an ACC pin, I haven't investigated that yet as I was powering the RaceCapture from USB (the wiring diagram shows it as mentioned above, but I didn't actually confirm)

I need to double check a bunch of this data, feel free to play with it on your own time. I'd like people to not make a mess of the spreadsheet, but if you do... it's on you haha
