Today consulting Michael from the Lambda project, he told me that I need to make a connection from the Wideband output (0-5v) Direct to the original ECU signal of the oxygen sensor, to do datalog temporarily and then reverse this so that the ECU the car back to work with the original sensor (0-1v). Well, now my question arises in the fact that I will be putting 5 volts to that signal cable that originally works with 1 volt. This is safe??!
This connection would be temporary, I commented, and it is because my wideband instrument (Prosport EVO series) does not have a digital output, but an analog one. It has two one of Narrowband 0-1v
and Another Wideband 0-5v output but both are analog.
