Lambda to CAN. 2nd sensor

Hi All,
I did ask on FB but didn’t really get a valid reply.
I have a second Lambda sensor and Lambda to CAN interface.
How can I set the log to view the second Lambda voltage the same as Lambda 1.
ie 0v- 1.5 v.

I can view the analogue gauges and they seem to work, but they are reading 0-5v.
i want to make it easier for my tuner to see the second lambda.

Thanks for looking.
