I'm still messing with this and am just trying to get it solid for reliability, I had some issues with my headunit crashing when all wheels speeds were being used. For it is solid with just the OBDii speed in kmh, once GPS has a kph conversion i can disable OBDii mapping altogether.
It worked beautifully last time out, It's is all hardwired in the car now with an on/off switch.
Here is the data from my record lap at Queensland Raceway. Fasted NA 86/BRZ.
The two laps highlighted are on different tyres, street tyres and hoosiers, category records for each :)

I have just hooked a up a pressure gauge and it works well, I intend to get some data before I install a baffled sump.

Did anyone get rpm working via can? The address stated in post one seems to be close doesn’t quite work right, it’s somehow dependent upon throttle being applied as well.

Has anyone had any luck with ambient temp? CAN or OBD, I’d love to plot this against intake temp.

I've collected info on CAN PIDs for these cars from numerous sources and created this page on the GitHub for my DIY CAN reader:
https://github.com/timurrrr/RaceChronoD ... db/ft86.md
Hope that helps RaceCapture users too, and I'll appreciate additions to that page!

As for the ambient temperature, I believe the OBD-II standard PID is 0x46 service 01 and data is in the first byte, encoded as

Code: Select all

ambient_temperature_celcius + 40
i.e. you need to subtract 40 from the raw value to get the value in celuius.

Could someone check the existing FRS / BRZ preset mapping and check if it matches the latest? If not, we can update the system default, just post the RCP file here.

Thanks for all the hard work reverse engineering this!

attached is an RCP file you can just load, note you will still need to select the channel within gauges.

Bringing back an old thread... this link is broken, wondering if someone has it or if crimespree would be able to host them again. TIA.

FYI - The latest mapping for this ECU is already available in the system presets. Press the cloud update button if you don't see it in the list.
