    trying to figure out the lc1 and how to set it up correctly. the volt / ? + .5

    The lc1 says it is 7.35 afr at 0 so that is .5 lambda
    I have it like this
    Volts/4 +.5 it's way off. What is the correct setup for it to read properly. I believe this is why all my histograms show error. Because it reads like .5 .6 at idle lambda. I'm telling it lambda also. Also set up the lc1 to show lambda. Now I'm not sure if that's correct either. Because the db series gauge only reads afr. Can I still tell it to be I'm lambda and the gauge reads in afr.
    If no how can I set up the lc1 and setup a error afr and ve error maf error histograms?

    If you don't post your tune and logs when you have questions you aren't helping yourself.
