PLX wideband install

[jbt]

When connecting a PLX AFR to a Kpro 4 via analog input. One has to connect the 2.1 mm connector to switched power and ground.
But then is it then just the grey 0-5 WB cable that one have to connect to the analog 0 input on the kpro, or should one also connect a cable between the ground pin on the PLX 4 pin analog connector and the one of the analog grounds on the kpro?

I do not believe that there is an analog ground on a PLX wideband.

K-Pro 3 and K-Pro 4 are the same in this connection.

The lower left pin on the 4 pin connector is some sort of ground pin according to plx manual. Should it be connected to the kpro anaolg ground?

Does it work without it connected?

Yes it works but I still don't know if the 0-5v output from the controller is affected by the not hocking up the ground or not. Can I connect the wide band controller to both digital input and analog input at the same time and then compare the values?

You should just compare the datalogged value to the display on the PLX.

I don't have any display for the PLX only the controller unit. Can I datalog both the digital input and analog input in the KManager at the same time?

That will not tell you if it is reading correctly or if you need a voltage offset. You could try using a multimeter to convert the voltage to a AF value and then see if that matches the datalogged value.
