Ahh, that's unfortunate. I was under the impression that you could have one of the connections set to broadcast only (which is what I want anyway for the rpi) and the other could be used normally for tuning at the same time. Not a deal breaker but that is a slight annoyance.

How'd you go about connecting the db9 to the pi? usb converter, external board or some sort of gpio magic?

 

You can broadcast CAN and tune at the same time. So you could to that route.

Again the ms3pro has 2 USB connectors and no db9. But a db9-usb should work fine.

 

How does everyone find the reliability of bluetooth on MS2 vs wired connection?
I've had issues with my wired connection dropping signal, not sure if due to shitty laptop or shitty wires, or EM noise....

I plan on building an RPI, just looking for a screen that has a volume **** that can be wired in, I'd essentially want GPS, audio, and Tunerstudio all in one.

 

Bluetooth works great for the connection between my phone and ms3. Almost no issues. I run msdroid over it all the time. It has gotten better on my Mac. I think windows might work a bit better, but it is noticeably slower for tuning and connecting than a wired connector.

 

So It shouldn't be used for VEAL Autotune, but is fine for display purposes?
FYI, I'm using an MS2E, don't know if that matters. Need to find a reliable bluetooth adapter now...

 

It might be fine for VEAL, never tried it.

 

I used it with VEAL with success. Though I'll primarily be using a wired connection now. For a Raspberry Pi that's mounted in the vehicle, I don't see why bluetooth would be considered.

 

You can tweak the GUI to suit the Pi screen, and you have the ability to fullscreen the VEAL menu so you can see all the cells etc. It works really well!

 

Yeah, I know nothing of coding.
I just struggled to learn how to tune and turbo my car without asking redundant or stupid questions on this forum.

More research is needed, or a stable GUI image I can download and use out of the box with minor modifications to suit my needs.
I'll be over here reading and learning until that time.

 

I'd certainly be interested in a full write up if you had the time! Speaking or myself, my Miata is 25 years old and just over 100,000 miles. In most states, including mine, this means its over its mechanical limits anyway. So an odometer is irrelevant as long as you market it that way if the vehicle was sold.

I'm kinda torn, I love the Pi concept and your project looks great. I wish I had more time in my life to hack on stuff these days, but I would love to do an FPGA based solution. I started to reverse engineer the digital dash a bit in one of my old daily drivers, a 2009 Cobalt SS. It was a pretty cool device and obviously well suited/rugged for the demands. Continental built it for GM. It just parks itself on CAN and watched for PID's from the ECM like you would expect. I ended up having to drop the project due to time constraints.

edit: here are internal pictures of the unit, if you are curious: http://www.ecimulti.org/gallery3/ind...8/album171/RPD

Ex:

 

Any chance you'd be willing to share the CAD for that design and which parts you used? Would love to do the same thing with my dash.

 

Sure! It was designed in Fusion360. I am pretty sure I could export CAD files from that. It needs a bit of cleanup though, so I need to get that sorted first.

 

Managed to get a close look at the installed unit. Seems like the fitment is good and without any adjustments needed. Starting a write-up this week.

 

Any update on this?

 

I'm late to this party but check out the teensy 3.2. I got one up and running with a CAN transceiver, an OLED screen and a circular LED strip to read CAN variables, and also read the digital output from my LC2 to broadcast to the ECU over CAN. I got it all together and working but never build an enclosure. My plan was to simply replace the dummy-light oil gauge with this, but it's still sitting on the desk in my bedroom a year later.

 

some were asking about safe shutdown. This is the route I'm going for

Hi!

Is anyone of you capable of java development? How about addressing the Pi GPIO Pins by a TunerStudio plugin? I had someting like F1 style shift lights in mind or a segment LED gear display.

best regards

Martin
