Wideband with non-linear voltage output

How can I datalog a wideband with a non-linear voltage output?

I have an older FJO controller which doesn't allow switching to a 0-5v linear output.

get a wideband that does...thats how

Brilliant answer. I was looking for something more along the line of: use analog input 2. Will I be able to overlay/datalog this way?

yes you can use the analog inputs, but you will need to enter the full conversion table. You will not be able to use it for running in closed loop.

My wideband allows me to run a non-linear or linear signal to the ecu. if i use the linear do i have to input the voltage vs afr?

You must always enter the voltage vs. afr or you will not have anything for the ecu to reference for conversion.

makes sense :oops: what is the difference between linear and non?

linear means straight line

lol...in regards to the wideband signal? the signal is straight ok, so the voltage vs afr is easier to input?
