CAN USB connection

Hello all, I’ve been having quite a bit of issues with looking for where to connect a usbcan to. Am I required to have many of them for each individual sensor or do I require only one? Any help would be appreciated

2002 Subaru WRX

You need only one adapter to connect to your vehicle. RealDash compatible adapters listed here:

RealDash | Manuals | Supported CAN/LIN Adapters

Its quite uncommon to have a CAN bus on 2002 vehicle, are you sure your Subaru has a CAN bus?

I have a waveshare adapter coming Tommorow, my best guess on how to get anything will be pull from the CAN HI and CAN low from the obd2 port in hopes it’ll work faster than my Bluetooth obd reader

post here if that works

I use the waveshare can on my BMW f22 with no issues. Real time data.

you were correct, I’m gonna be scrapping project. I’ll end up making another one sometime when I acquire my next project

Tried to run it off of OBD2 as that was the only CAN HI/LOW I could find. No avail.

Your model most likely has a CAN to connect somewhere. Mine is PreCAN for subaru (2005 was when it was implemented)

I purchased this… which option in Realdash did you use for this?

Hello there, what setting of can description on realdash do you have to use this adapter on your bmw please, i have one on audi a7 and it can read can but get nothing working on dash, thanks on adavance.

Also… can this work on an Android Headunit?

It could most likely work as long as your Android distro supports that specific protocol. I wouldn’t see why it wouldn’t

However don’t quote me on it

Where are you tapping off of? Maybe I can help you out a bit

I have tapped of my gateway module under my seat and it sees the can signal on the realdash app but gauges wont move as i dont have the audi pids on the realdash can selection, i have to find Audi DBC files online but had no luck so far

You are going to have to make your own DBC file. You can try to see if a VW file would work in some small way, and build off of that. Other than that, its trial and error and reverse engineering using the Realdash CAN Monitor…

If only i could find any file tbh, spent 4 hours looking today :confused:, thanks for reply mate

I found some dbc vw files but cant import them, it sees them in file explorer when i select them but when i import it nothing shows up in the list, any ideas please.

I wonder if file description is wrong format?

Cheers guys

Here is the DBC converted to RealDash XML. Nothing interesting there, sorry.
