RaceCapture/Pro supports standard OBD-II PID querying right out of the box, so if that's the case we're already good to go.

If there's a streaming protocol, that can be adapted as well for super-awesome mode :)

That's all kinds of win. Thanks for coming over and hanging out with us and sharing the awesome :)

thanks too! Any more questions, just let me know. In the meantime, I have an evaluation Hydra on the way from Flyin Miata to do some CAN bus integration.

:o

Direct CAN will have all the parameters and not only the ones that can exists in the OBD-II. And with direct CAN to MS2/3 no extra thingy needed, just two wires.

I have no idea how fresh this is but it's a start and contains more facts that I can digest.

I am very interested in this. I recently bought a tablet and was thinking about mounting it in my Miata. With my need for telemetry, this looks like my ticket. Like others, I am running a MS2. From my understanding in this thread, that should not be a problem.

Thanks, XeNoMoRpH - if we can get the channel to CAN message protocol we can certainly help create the script to make it work.

Well, I preordered. I guess I can start working on a tablet mount :) and have a project for the winter.

MS3 offers CAN broadcasting using standard 11 bit headers. I assume you can map it out if I supplied a dbc file?

Email me (ben@diyautotune.com) and we'll get things lined out for mutual interoperability.

Hi Ben,

MS3 would likely be very straightforward to integrate. I'll drop you an email and we'll do a write-up.

thanks!

We got our hands on a Race Capture box this afternoon and installed it in the Chump car, the evening of a 14 hour race. We don't have power at our pit, so we worked under lights until our generator failed, at which point we found a Mexican restaurant with fajitas and margaritas.


So for this event, the Race Capture doesn't have near as many inputs set up as we would like, but it is in the car and transmitting data. I'm really looking forward to crunching data at pit side tomorrow. The ability to access this telemetry data real-time has the ability to transform the way we endurance race.


Anyone interested in watching live streaming can do so at this link:

Green flag 2-7-15 @ 8am eastern. Checkered at 10 pm eastern. Go #8 Hong Norrth Tr0nsAm!


Expect a more comprehensive write up and review later. Off to bed now.

Glad we got you up and running! Just wait until we get CAN bus data flowing. :)

Live data is available and running. Race Capture's GPS based lap timing is showing within .03 of transponder. Pretty good!

Pretty good timing with the 50Hz module; and we still have some optimization tricks to do!

You can also click on multiple laps on the left, compare the lap-lap data in the charts, and also zoom in on the GPS and see the actual line taken between laps.

Race fast and smooth!

Sub for a full review and MS3 compatibility.

Progress - Got the MS3-Pro and RCP wired together on the bench with power and CAN bus connections.

We've added to our CAN bus database the MS channels we think people would find most interesting. More can be added, of course: CAN Bus database - Autosport Labs

Next, need to enable CAN channels in the MS3-Pro and write the script to map the CAN bus data to RCP virtual channels.

I think I'm going to be picking up one of these.

Any word on CAN integration with DIYPNP and MS2 ecus?

We have the initial mapping in place with what we would call the Megasquirt standard mode CAN support. Ben advised me there's a more concise "Dashboard" mode which we will also add support.

This is a trivial integration for us - it's going to work great. Our MS3 Pro will soon see life in the Exocet kit - arriving SOON :)

Beginnings of the documentation is here:
Megasquirt CAN - Autosport Labs
CAN Bus database - Autosport Labs

Looks like its working nicely for the MS3 pro but I just want to make sure I can get this set up on my DIYPNP as well. They both have CAN output so I'd imagine it's capable but I just want to make sure it would be just as easy to integrate as the ms3pro or close to it.

There's absolutely no CAN system we cannot integrate. If it's undocumented, that just makes the reverse engineering more fun. :)

So, yeah.

Ben can speak to MS2 / DIYPNP better.

The MS2 'standard' CAN broadcast mode should work now (probably just need a little more documentation from Brent, unless you're pretty code savy). If you're not adventurous, wait for the MS2 'simple' CAN broadcast mode to be finished. I don't have an ETA, but I don't think it will be long.
