Data logging canbus/obd2

imported_mega · 09-02-2019, 02:52 PM

Anyone data logging at the track?

I have a racecapture mk2 and I"m data logging canbus, obd2 and a couple analog sensors on my R53 mini.

OBD2 is too slow for most things, except nice to have like IAT, anyone else pulling canbus? If so what channels are you logging?

Hoping oil pressure is easy to get, aim dl did not have it listed but did have quite a few other channels

My MHD doesn't appear to be monitoring oil pressure.

Does the car require new sensors?

imported_mega · 09-09-2019, 06:24 PM

from what I found there is no pressure sensor, just an idiot light sensor that triggers at like 7psi

N54 doesn't support it nor has it been patched for it. If enough people hound MHD, they'll do it. Until now, they don't really give a shit about anything except straight line performance. Took a couple posts years ago to give us waterpump control when it was already in public XDFs.

Wow that sucks. How is everyone monitoring it then?

Another sender/ext gauge/logger is your only option. Keep hounding MHD...

MHD cant fix it, there is no pressure sensor on the engine. It has an on/off switch that triggers at 7psi but that's it

where is everyone else tapping into the canbus? I need to log off the pt-can pair

gmx · 10-09-2019, 08:20 PM

They *can* if they use a "spare" 0-5v input and N55 sensor. It's the same thread IIRC.
But everyone just wants to use ethanol and flex fuel. As I said, they only care about the masses.

anyone know the pt-can ID/offset/lengths for what I'm missing? mainly looking for wheel speed and brake pressure at the wheel so I can monitor what the DSC is doing

RPM ID 170 offset 4 length 2 signed little endian conversion raw x .25 / 1
pedal position
TPS ID 170 offset 2 length 2 unsigned little endian conversion raw x .00154 / 1
wheel_spd_fr_lf
wheel_spd_fr_rh
wheel_spd_rr_lf
wheel_spd_rr_rh
clutch_switch
Steering ID 196 offset 0 length 2 signed little endian conversion x -.04395 / 1
brake_pr_fr_lf
brake_pr_fr_rh
brake_pr_rr_lf
brake_pr_rr_rh
brake pedal pressure id 414 offset 6 length 1 unsigned little endian no conversion needed
temp_outside
oil temp ID 464 offset 1 length 1 unsigned little endian conversion x 1 /1 +-48
map
gear
