LC1 via the fuel tank pressure sensor
Well I sort of made it work. I hooked the output up to the fuel tank pressure sensor and put the ([PID.6420]/.5)+10 PID in. Couldn`t seem to get it to work, the AFR was on around 14.7, but at 12 the HPTuners readout was high and around 17 the HPT readout was low.
I looked at the LC1 outputs and realized that function would not work. LC1 output is 0v = 7.35 5v = 22.39
So 22.39-7.35 = 15.04 / 5 = 3.008 AFR per volt.
So I put the function ([PID.6420]*3.008)+7.35 and my AFR now seems to align.
Now my problem is fine tuning the calibration......the gauges (both the LC1 and HPTuners display) bounce so fast that I can`t really tell if I need to adjust my function. How did everyone else slow the bounce down so they could fine tune it?

The LC-1 emits a flat voltage while warming up,
this can be set in the advanced analog output settings.
Power it up and measure the voltage with a DMM to see if it matches the HPT reading.
If it doesn't, add the difference to the voltage range and remake the expression.
