Default logworks vs digital afr gauge

Until today, I've never connected my lc1 to my laptop. I have always relied on the pod mounted digital gauge that came with my lc1.

Logworks is pretty cool, at least from what I've seen so far but I have an issue already. The two afr gauges don't agree with each other. My in car gauge shows 16 to 1 at idle, and logworks switches between 14 and 15 to 1 at idle. What really gets me is under boost, while the pod one reads 11.5 to 1 the LW3 shows 9 to 1!

What the hell is going on here? How can I trust either?

I just calibrated the o2 sensor per the instruction manual (free air, push button)

trust logworks, its a direct serial input to the controller.

is your gauge grounded to the same spot as the lc-1?

I honestly don't remember because I installed it last year, but I know I followed the instructions to a tee.

Maybe this explains why I've only been averaging 19-20mpg lately? lol

I'm going to try and do another free air calibration just to be sure, I'm just waiting for everything to cool down again.

Thanks for the advice!

Well, same results after calibration. Digital gauge reads higher than logworks3.

This is some bullshit! It's like two points higher at all levels. Should I trust logworks and start cutting fuel everywhere?

is your output voltage what the gauge is looking for?
