Trans data over CAN

[Raymond_B]

I am sure every time you see my name on a post you're like geeeeze

Anyway are there plans to add transmission data to the CAN broadcast document?

[jsmcortina]

It's on the roadmap but the details aren't fleshed out yet.

I was just wondering that last night.
I think gear info does show up in my engine logs, but I'm not sure if that's over CAN.
The trans temp would be cool to see if I had to pick one item.

[jsmcortina]

That data should be possible to collect using the existing CAN settings and 'generic sensors'

I had some similar questions and wanted to be view transmission temp while on the main engine tuning screen. I was able to combine projects and can now view all tranny data while on the engine consoles setup and all the data is in one log now

[litneon]

Is that a simple thing to do? I'll try to figure it out.

Thanks for the heads up.

Which part? Creating a combined project is covered in the Trans manual. (Section 7.3)

I'm still diving into canbus. So it's really not my thing, but the setup instructions that James provides in the trans manual walked my right through it. What's nice, is there is a simple drop down to let you toggle between engine and tranny without changing projects. All in one place

[jsmcortina]

That works for laptop tuning, but won't let you record trans temp to the SDcard. Configuring the MS3 to fetching the data itself (as I alluded to) will do that.

If I can figure out the CAN stuff, believe me anyone can See my saga in the "Other Development" section. The hardware required to read the can data is amazingly simple and cheap. It does get tricky on how you want it displayed however, I am fighting with that right now. My 12.00 LCD does not do well with rapidly changing values, but I have a conversation going on the PJRC forums on how to make up for that in the Arduino code.

I've had two scenarios in mind, a large (~7") display in dash or simply a smaller 2-3" display that reads only pertinent data. There's several projects already like that in the "Expansion Board" section, but again I was looking for something in the 2-3" square range for the supplemental display.

I think CAN is the best, most reliable, and fastest way to display data and is why I have gravitated to it. I have plenty of ways to display TS, but dealing with Bluetooth/serial, a full blown OS and all the issues that come with it make me think it'd be annoying for day to day use and reliability. That probably can be debated many ways, but for me CAN is simple and straight forward.

[litneon]

You just reminded me... Has anyone developed a multi gauge yet that can read the CAN info? That would be really cool. Or something like the Haltech Racepak?

[Raymond_B]

Check out the expansion board section.

Love it! Thanks!

I am having issues adding the MS2 trans controller via CAN while serial connected to my MS2 ECU project in TS. A firmware mismatch is coming up after joining the trans contr in the project properties (pic attached). The joined process seems to be changing my ECU parameters all over the place to the point I had to reload a previous tune.
If laptop serial cable is connected to MS2 trans controller in TS, all is good and TPS, Engine Speed, Engine Temp, etc are showing up fine.
Attached is the MS2 trans controller MSQ, MS2 ECU MSQ, and pic of error when adding trans controller via CAN.

[jsmcortina]

Could you post a screenshot from your Project Properties -> CAN Devices page ? I suspect a misconfiguration there.

James

Attached. This is the CAN devices page from my MS2 ECU.

[jsmcortina]

See page 59 of the Trans manual - you'll see that your "Device CAN ID" is incorrect.

I see only 50 pages in the trans control 1.0 PDF.

You don't have the latest version. Go to the Manuals link above.

I just noticed that. Thanks James....
