Did I program my LC-1 wideband wrong? I've just installed a brand new LC-1 on my car. The calibration went fine, but I just hooked up a digital gauge (V-gauge from Trick Performance) to it and there's no AFR reading. 
What do you think could be the cause? I used the yellow wire (analog out 1) of the LC-1 to connect to the gauge.
Maybe I programmed it wrong with LM Programmer? The instructions of my gauge say "The analog signal of the wideband must be a linear 5v ramp where 0.5v = 10 AFR and 4.5v = 20 AFR". So in LM Programmer, I clicked on the "Analog Out 1" tab, then I ticked "use air-fuel-ratio" (instead of Lambda), and on the first line I put 0.5v and 10 AFR, and on the lower line I put 4.5v and 20 AFR.
