[Can lambda not found]

I will attach my tune when I'm back with the car but it is the link can lambda and I did try every single speed options hoping that was it but nope

[Can lambda not found]

Hi guys, I have a 300zx plug in ecu and I'm trying to get my can lambda kit to communicate to it. I have checked the setup settings, cleared and re-done them. The can unit is getting 12v but still doesn't show up in can devices. I have it wired in with the canjst cable. Why is it not showing up or am I missing something. Cheers, Jack.
