DIY Mini-Dash LCD Gauges Update

Well... I went down another rabbit hole and spent the morning reading up on Real Dash and looking at example code. It looks to be very flexible as everything can be defined by XML files. Nice!

To get the 350/370 OBD live data options (about 40+ depending on year) is very easy, to add the CAN bus data into the Real Dash app doesn't look too difficult.

However, I have more research to do to understand how I can add in the analog sensors (pressure & temp) from the bluetooth sensor server. There are a few options that I will look into, but it isn't a high priority for right now.

I was about to suggest that for you Real Dash with your MX+ would give you just about everything you may want (except for oil pressure) BUT all the Real Dash layouts are horizontal and your tablet is vertical. Too bad

I'm letting my imagination run away with me. Like what would a low cost easy to integrate sensor server look like that runs on bluetooth. You have all the parts already built for it just need a generic data transport that lots of "clients" support.

The other ones out that that do similar things are very expensive and usually part of a larger ecosystem like Motec. And don't have bluetooth. I think you could get them to a tablet via the MX+ and custom PID settings in the apps tho. But honestly I haven't looked at it.

Is your project going to be open source? I would be interested in poking around the code if so.

Just to be clear, the bluetooth sensor server is just for the analog sensors (temperature and pressure) that are in the engine bay, eliminating the need to bring wires through the firewall.

The bluetooth data is then merged with the CAN bus and OBD live data, which is displayed on the LCD display.
The only generic (or well documented) client I am aware of is RealDash and maybe RaceChrono. (overlays gauges on track video)

Down the road I will spend some time to see how I can all the data into those above items. The good news is, that anything can be changed to fit another format.


With the OBD system, it can only have 1 master (MX+) and one slave (ECU) as the same CAN bus addressing IDs are used for the scantool and ECU. I can't think of a way to add data to the MX+.

For right now, it isn't open source. I have a few thousands hours in development over the past 2 years and I need to get some kind of return.
Down the road I would love to let people more talented than me to see what they can do. -OR- I may just give up and get a real job
