BE 5.931 Wideband O2 config issues

Unread post by JMG9350 »

Binary Editor performed an update to Ver. 5.931, my tune files have disappeared, and now the way the wideband is configured in BE has changed, and no longer works. I have read the help/user's manual, and I have entered the information how I think I understand it, and it still will not convert the EVP 0-5V signal to AFR.

This all worked before the update. Does anyone know how to configure this, and can explain what I'm doing wrong?

It is set up to log in the payloads, and it just shows a range of 0-5V. It is receiving information from the wideband, but it is not converting it to AFR. I emailed Clint Garrity, and have not heard anything in 4 days.

This example of the unchanged EVP volts to AFR, there are no parentheses in the expression formula. Should I try that?

Removing the parentheses does not correct it either. I'm at a loss. Clint still has not responded to my email either

Turn off auto updates and go back to an earlier version is likely the solution for now.
