What is my mistake? Can´t see lambda2

Hi
my name is Michael, 44 years old and i come from Germany. I bought a new m400 and a LTC. My first project is a Honda rvf 400, V4 engine and i want to ride it on the track with fuelinjection. Now it works, we found 5ps on a dyno compared the carbs. I want to use 2 lambda sensors. One for the 2 front cylinders and one for the 2 back cylinders.
Ltc told me lambda is working. I use the second lamlda as plm over can, but when i coupled to a laptop i don´t see any values. Is there any mistake? I hope anyone can help me.
If you need more information pls tell me.
