Quino Posted May 7, 2021 Report Share Posted May 7, 2021 Hi, I'm designing a Data Adcquisition to measure the torque of a motor on a bench and I need to know the sampling frequency of the Analog Input Voltage 0-5V in order to determine the RC filter I want to introduce in the signal which is sent to the ECU. Also, it would be very useful to know if the proper ECU has any internal filters in this pin configuration. Thanks in advance! Quote Link to comment Share on other sites More sharing options...
Adamw Posted May 7, 2021 Report Share Posted May 7, 2021 I will have to confirm sample rate with engineering as I dont know off the top of my head. There is significant hardware filtering on the analog inputs and the software filtering varies depending on the function selected. Quote Link to comment Share on other sites More sharing options...

I'll wait for your confirmation about the sampling frequency Quote Link to comment Share on other sites More sharing options...
JesusGG Posted March 24, 2023 Report Share Posted March 24, 2023 Hi, does anyone know the answer to the question above? Thanks in advance Quote Link to comment Share on other sites More sharing options...
Quino Posted March 30, 2023 Author Report Share Posted March 30, 2023 Hi, Maybe @Adamw can achieve that data! Regards. Quote Link to comment Share on other sites More sharing options...
Adamw Posted March 30, 2023 Report Share Posted March 30, 2023 I only had a vague recollection so I just asked one of the firmware engineers, they are sampled at 500Hz. Be aware there is more hardware filtering in these older generation ecu's compared to modern stuff where there is more power to do most of it in software.
