Sampling rate higher than 50Hz

Hi,
I cannot obtain data from RCPro MK2 higher than 50 Hz (Analog / Acc / Gyro). When I switch the sampling rate to e.g. 500 Hz, I obtain consecutively 10 same numbers. At 1kHz I obtain 20 same numbers. Tried with firmware RC2.9.0 and 2.8.7.

GPS, Race Timing, Telemetry, OBD, CAN and everthing else is set to OFF.

Any idea?

I'm guessing accelerometer doesn't sample any faster than 50 hz.

So i donĀ“t understand why it is possible to switch the sampling rate for accelerometer to 1 kHZ :).

And what about analog inputs? In datasheet (https://www.autosportlabs.com/racecapturepro-2/) is shown sampling rate for analog input 1kHz, but in log is only 50 Hz. Can you please test it? It's not necessary to connect any analog sensor, you can just set the precision to 6 (Analog Sensors/ Customize Channel) and log a noise.

I need to analyze dampers travel velocity and 50Hz is useless....

Hi,

Are you referring to analog channels?

If so, please ensure you're on the latest firmware and do a short test log with analog channels set to 1KHz and post it here so we can review.

Thanks!
