Work in progress. I found some ID's on the web. I'll post the ones, if any, that work.

Thanks - did you mean to include an attachment?

Here's the text version:

Are CAN ID's hexadecimal?

Thanks. Looks like the CAN IDs you posted are hex; the CAN mapping dialog receives CAN IDs in decimal.

OK, so I am trying this...notes first off

• 2015 Fiesta ST (stock ECU and ECU program)
• RaceCapture Track, 2.11.0 Firmware and 1.9 App (both Windows and Android)
• Extra data desired for now : Steering Wheel Angle, Brake Line Pressure (as proxy for how hard I am braking), TPMS readings
• I AM able to connect and get the "extra" stuff listed above via the Android ForScan App thru an OBDLink MX, so I do know the data is there and exists

As an example on Steering Wheel Angle, what I have from the net that I think should work :

Name ShortName ModeAndPID Equation MinVal MaxVal Units Header
Steering Wheel Angle STWHEEL 223302 ((signed(A)*256+B))/10-780 deg ABS

So If I'm reading that right...

OBDII PID Tab : OBDII PID = 13058 (3302 in hex, translated to decimal) , Mode = 22h
CAN ID Match : left as 0 for CAN ID and 0 for Mask, on CANBUS 1
Raw Value : Offset = 0, Length = 2, Signed, Big Endian
Formula : Raw * 1 / 10 - 780
Units : no Conversion

Needless to say, it doesn't work yet in RaceCapture

So, anything obvious I'm doing wrong?

Or, any tips on back-engineering the data from ForScan? If I can get that, I should be able to decode LOTS of things here

First, wrong thread. You should be posting this in the OBD mapping topic. Second, mode 22 is a Ford proprietary mode. It's possible that a code needs to be sent to the ECU before it will respond to a mode 22 PID request. CAN would be better.

I bought the MicroChip CAN bus reader and an OBDII to RS232 cable.

ID 513
offset zero
length 2
big endian
raw/4
no conversion

You also have to turn on CAN channels, which was why this didn't work the first time I tried it.

I was able to get the CAN based RPM data into Harry's Laptimer. I haven't tried the old RaceCapture iOS app yet because I can't retrieve the data even if it worked.

Throttle Position should be relatively easy to find and Mass Air Flow not much harder, but wheel speed and Engine Coolant Temperature are going to be a bit more difficult.

Great you got that working. Love how much broadcast CAN data is available in these cars!

Next app release or following we'll have the preset feature available, which will make it easy to bring in a group of mappings in on one shot.
