Kpro V4 CAN to Plex uSDM -100

[Omy]

Hi all,

Attempting to setup CAN calibrations to Plex uSDM-100
I understand that Kpro transmits AN0-AN07 as a raw voltage.
I am using Bosch temp / pressure combined sensors.
I have used the template Plex has for Kpro however the display shows the Raw Voltages coming from the sensors.
How do I convert this to temp and pressure at the display?
The KManger appears to be showing the correct temps and pressures.

How do I workout the formula to display correct values with Raw Voltages? I guess KManager does the conversions internally.

Thank you for the reply, I have manage to get the pressure readings working however I am unable to do the temperatures as the Plex unit does not do linear voltage calibration.

I am trying to get the lambda reading displayed correctly which is giving me great difficulties. What does the Hondata output through can for lambda? Any help with the formula that can convert this output to Lambda for the Plex?

How do I use Lambda (16bits) 32768/lambda (lambda)?

You will need to talk to the manufacturer of the display you are trying to use to see how they interpret the CAN protocol that is sent.

It’s configurable input for the Plex, I just need to know the CAN data format to do the conversion.
