I put this in the Coding sub Forum but I figured it can't hurt to put it in here since it's relevant to track driving.
I am in the market for a Digital Dash with data logging capability. I've narrowed it down to the AiM MXL 2 and the AEM CD-7.
The AiM MXL 2 is known to work with BMW DMEs. Splicing into the CAN High and Low wires gives you a ton of data: steering angle, brake pressure, much more than what you could get from a standard OBD2 dongle. AiM has profiled the BMW DMEs specifically and so all that is needed is to splice into these wires.
AEMs CD-7 does not have this profile. It has their own standalone profiles, obviously, and some others like HONDATA, where you splice in to CAN High Low like you would with AiM, but not the BMW DME at this time. The CD-7 can plug in to OBD2, but typically that data is quite limited, as all that is federally required is emissions related.
However, I've been researching the depth of data that comes over the K-DCAN cables popular for MHD flashing.

Apparently steering angle sensor, braking force, and other data streams that interest me come over the KCAN protocol. They could be displayed in MHD but the app just doesn't log those channels.
If I used a K-DCAN adapter like this:

do you all think the CD-7 with the OBD2 interface could display the data I'm looking for?
Thanks!
