hi, I have a problem!
in my pra ecu I connected to pin E15 ELD wire (output wideband 0-5v) of wideband plx-Afr sm!
But as I understand it is only able to Datalog right?
connections that have to do to use the wideband as the first probe to read?
or is it better to use the wideband for Datalog and narrowband as the first reading?
what is the best solution?
excuse my English if I made mistakes :oops:

The wideband input from an aftermarket wideband can only be used for for dataloggin purposes. If you want to run in closed loop you will need to input the narrowband signal from the PLX into the OEM Primary O2 input on the PRA ECU.
