LC1 Expression - Linear or Non-linear?

[LastCall]

Newbee question:

I am in the process of hooking the LC1/XD16 combo up to EFI Live. I see there are 2 ways to express it, 1 for linear and 1 for nonlinear. Which method should I use?

Thanks!

If you are using V2, connect with serial instead of analog.
The LC1 has predefined pids, your lc1 analog output values will be:

0.88333 @ 10.00 AFR / .068 LAMBDA
4.21667 @ 20.00 AFR / 1.36 LAMBDA
