Oil pressure—does it come through the canbus?

[M1500Z]

I have this posted in the M2 board, but striking out thus far. The discussion around oils in another thread has me wondering why I don't get oil pressure readings on my Aim Solo2 DL. I get a ton of other data (neat if not useful) but no oil pressure. In the S55 technical documents, BMW states the S55 uses a sensor that provides absolute oil pressure reading to the DME but that's it.

I did confirm that I can pull oil pressure with BimmerLink through the OBD (actually a ton sensor data available with that method). So my question is, now, does that mean you can get oil pressure through the canbus and if so, how might I get my Solo2 to log it? I attempted to search this a bit and the search kept failing for some reason. ¯\_(ツ)_/¯

You're limited to the ecu profiles that AIM provide, unless you can get a better profile from someone else. A few german companies have their own (like Custom Racetec), which pull a lot more info from the canbus.

Bad-ish news
This is correct. I spoke with Aim support and they basically said that there isn't an easy method for adding an additional channel to their protocol. It's either use their protocol or use a user-created one (starts from scratch).

Good-ish news
The person I spoke with said they could look at adding that information to their protocol if I can provide some details about the particular channel I'd like added.

• Arbitration ID (believe this to just be PID)
• Bit type
• Bit length

So now, and this is a bit of a side project, I'll see if I can sort it out. It looks like I'll need to figure out how to sniff the canbus and then find the channel for oil pressure to provide the details. There are a couple open-source apps I may be able to use for this and hoping I can either use my enet cable or bluetooth OBD adapter with them.

Yeah thats no easy task, i attempted it for a while but there is a tonne of traffic on the canbus with these cars. It would be much easier to get a profile from one of the german race prep companies, that has everything aim has and more in theirs
