Reverse engineering CAN bus traffic (something to show, something to ask)

Brigadir · Jan 8, 2023

I'm digging into HS1 and HS3 CAN bus traffic in my Mustang, and was able to decode a good portion of drive-train data. Here is the summary, hope it will help some enthusiasts: https://github.com/v-ivanyshyn/parse_can_logs/blob/master/Ford CAN IDs Summary.md

What I'm still trying to uncover - how to get current engine torque or HP. I was able to find engine load data (it looks reliable based on comparison with the corresponding ForScan graphs). But it looks like there is no raw data for torque in CAN bus which matches the graphs of variety ofOBDII apps. But on the other hand there is some data that correlates with those graphs. Also I couldn't find throttle position data, but it is present in ForScan (maybe because ForScan requests it explicitly).

So, looking forward to discuss this topic with enthusiasts.

Torque or power would have be calculated ? It's not like they're being measured in any way.

Some of us are interested in this since we might be using telemetry devices for motorsports - if you look at RaceCapture forum (Autosport labs), they have some of the channels (steering angle, brake pressure and few more - I think including TPS) figured out. I am reading steering angle and brake pressure using Race Capture and it does work.

I hope you're able to keep going!
I only have a minute understanding of CAN bus lines from my job, so I'm still learning how it's all organized.

Thanks for link to Autosport labs. Found this thread there, will check it in my car: https://forum.autosportlabs.com/viewtopic.php?t=6197

One hint for you, if something is on/off, then watch values in binary ( at least byte that changed ). It will make much more sense to you how to properly read certain values.

For example to you:
**0x3B3 (HS1 & HS3):**
* `b0`: 40 - headlamp off, 44 - headlamp on

0x40 = 01000000
0x44 = 01000100

Which means that bit of index 2 tells you that headlamps are on.

To test that in code, you would use bit operations for example:

b=0x44h

if ( (b & 00000100) > 0 ) { lamps are on }
or
if ( ( b & 0x4 ) > 0 ) { lamps are on }

Also, list of messages is documented by Ford in their workshop manuals, I'll post it in next post

Thanks, it's valuable info. Interesting if it's possible to map CAN IDs to these messages (maybe somehow enabling/disabling the blocks in ForScan, just as an idea...).

From my side I ended the investigation of drivetrain traffic and gave up for attempts to calculate torque

probably later will inspect multimedia commands IDs which should be not a complex task

what is your end goal? to have hp/tq show up on video overlay in racerender? Calculating those from CAN seems like it would be difficult to do from scratch. OBD apps seem to be able to do this reasonably accurately but i couldn't find any data on how they calculate it (assuming they are using engine parameters like fuel flow, airflow, Ve etc and not simply just the weight of the car and accel data).

That said, i took estimated hp/tq values from my accessport and imported that data into racerender from a .csv. There are phone apps that can create a .csv datalog of calculated hp/tq. i have no clue if things you mentioned like brake pressure or steering angle are supported via obd.

results: there is a good chance video and datalog are from different days, and i poorly synced the start of them.

Yes, I’d like to make some kind of gauge to display current torque. Based on all I know I could calculate it based on engine load data from CAN mapped to torque/rpm graph for the car. For example if engine load is 80% at 3000 rpm and torque on the graph is X, then actual applied torque is X*0.8. The question is to get reliable graph for the car (if it’s stock, there should be already recorded dyno graphs on internet). And we assume that the resulting torque depends only on engine load and RPM.

Regarding other apps - it’s also interesting how accurate they are for calculating torque. Taking into account that it’s hard to verify and that mobile develops aren’t physicians I have some doubts

Could you pick a bunch of points off this graph and assume they are all at 100% load, probably. i dont know how close part throttle mapping would be, not that it is as important. The app i have used in the past seemed to be fairly close to what my 2.2 ecotec puts out; 140hp/145 tq. at the time the car had about 100k miles and it was 0 degrees which is obviously colder than what the jsae spec tests at. The app can calculate the air density using ambient pressure and air temp.

Thanks for the graph. More I think about this idea to rely on dyno graph less attractive it looks. Actually applied torque does depend on environment conditions and fuel quality, so displaying some calculated number which doesn't take into account current conditions doesn't make a lot of sense.

Here are some graphs for stock 2015 Mustang from our comrades for reference:
