    wideband fluctuation

    my gauge reads great, the scanner on the other hand seems to fluctuate severelyt3.hpl. it reads as low as 10.05 (.06 Vs) to 16-17 and averages are about 2+ lower than what the gauge itself reads. At idle she logs 14.6-7 but the scanner says otherwise.

    im using the pro link cable

    i did the math from the AEM 40-4110 to calculate everything and that all checks out. so in turn i added a channel/histogram to read only voltage so no math was required and the same story bouncing between 0.05v-3-4v

    location of the wideband is at the end of the headers near the collector.

    could this be a timing/misfire issue where a ton of gas is blown out the heads causing a extremely rich reading?

    any thoughts/suggestions are appreciated
