Custom engine data display

Cement

I'm making a custom engine (and other) data display for the VQ37 as a part of my engine swap project (E46 BMW). I've currently got 5 Prosport gauges which I will replace with a single 7.9" wide screen display from Waveshare. This will display all of the current gauge content plus a lot more which will come from the existing Prosport sensors (for things not monitored by ECM) and the ECM itself.

Its based on an Arduino to do the CAN + sensor interface and Raspberry Pi to drive the display and host the Grafana dashboard + Mosquitto MQTT software.

Posting here as it may be of interest to some people who like to get down and geeky I'll not be posting all the updates here, but instead over at a NZ based forum: https://bimmersport.co.nz/topic/6783...gital-display/

Currently looks like this:

What OS are u running on the PI . I have seen builds of dietpi(linux) with custom dash setups. But didnt know if the Can was intergrated easly, using bluetooth obd2? I would think it might be more universal with a android build. Could even setup torque very easy then. And could even run somthing more powerfull then a Pi, and even cheeper like a old android phone lying around. One that can do video out OTG type-c.

I've actually just switched to an Orange Pi 5 as the Raspberry was too slow. The extra processing power and NVMe storage makes it so much better ... running Ubuntu on it (provided by Orange Pi).

The CAN is being dealt with via an Arduino which is wired in (drives my dash board, radiator fan etc) and am sending data to the Orange Pi as MQTT messages over ethernet. I would stay away from bluetooth dongles etc for this sort of setup where reliability is key.

I like the flexibility Grafana provides, you can make really cool looking and functional dashboards. Check the proper build thread I linked above for more recent pics etc
