Prolink cable channels disappear when connected to car.

All prolink channels disappear when connected to car. I have tried both channels and canbus. I have brought a new prolink cable same problem. I have the 0-5v signal on the prolink cables but as soon as I click connect to car all channels for the prolink disappear. What's going on here. Been months trying to sort this and no matter what the channels disappear even when just testing for signal with a AA battery.

Doesn't matter. I used the ac pressure sensor to get my wideband signal. $250 for the prolink is simply a waste of money. It doesn't work at all.

I am having the same issues. HPMVI2+ with a Prolink+, Version 5.0.4.
I am using Performance Electronics wide band O2's.

Thanks
