    have you watched this?

    could you use his math then divide by 14.7 to get lambda?

    saving for a wideband now, will be in your boat before long. will be going egr route
    Yes his video is how I set this all up to begin with, Everything went fine until I got to the chart section. I cant use his math even for AFR because for my gauge the math is different. Even though we have the same gauge the chart with the list of voltage and corresponding AFR has changed from his video
    But with my gauge the paper work gives you the math formula. And if I just pick a random voltage from the chart and plug it in it works on a calculator
    But not when logging. When Im logging the WBO2 chafrt is blank and then thers a big number when I stop like 456 It makes no sense. I cant believe that NOBODY on here isnt using this gauge and logging in LAMBDA

    Ok I got the EGR down in that box Now when I log it sits at 1. The gauge is bouncing from 1 to 1.2 or so but the chart is logging just one. Is there a way to bring more decimal places in. IN that same box theres a place that is listed as decimals and it was 0 so I changed it to 3 but it made no difference.
    I probably have to do the error thing but shouldnt the reading fluctuate?

    maybe try just 1 decimal point. im assuming you have egr in channel list. should fluctuate like gauge if set correctly. I dont have enough info on your chart setup to add much

    Yes the egr in the channel list shows voltage of course and it fluctuates quite a bit
    But in the chart I havent seen it move yet lol
