    How to. Innovate MTX-L Plus wide band. Jumpy vcm scanner reading.

    I can't for the life of me figure this out. The wide band gauge reads steady, while my reading in the vcm scanner is jumping so fast I can't read it. Please help.

    Does your fluctuate from 13.xx to looks like 16.xx ? I don't feel comfortable tuning with it doing that..

    You can slow down the sample rate by changing the Polling Rate. Click on the WB channel in the Channel tables and select Polling Interval. Will be set to the fastest (0 ms)...try 100 ms (10 samples per second) should calm it down a bit.

    Im curious as well. I have an MTX as well. I also noticed that they upgraded the wb sensors since i got mine. Had to reorder mine recently becuase a new onei ordered was not the right one. Apperently i have a 4.2, and the newer ones use 4.9.
    My wb is reading way leaner than what is commanded in my logging, i think its my tune, but cant help but think if its cause i need to calibrate it for some reason.
    and you point is?
