I purchased an afx 2 wideband and I was able to get the VCM scanner to read the right lambda after calibration. However I am unable to use the sensor input in the histogram for EQ Ratio error. The device that I transformed is pink in the math parameters under Marth- predefined-> lambda & AFR -> FX EQ Ratio error. I tried using the serial voltage input and writing a custom equation of

100 * (([3003.10]/5.197505198) +.411 - [50118.238])/[50118.238]

I'm still not getting any error displayed in the histogram.

When I configured this to the scanner I added the channel and transformed oxygen sensors ->equivalence ratio-> NGK AFX

I changed the function to

5.1975 and .411 and selected yes for option of generic sensor. Did I do something wrong or did I miss something. I also changed the parameter to the Ballenger Wide preset for the transformation and still no luck. I really do not want to tune this based on fuel trims so i am trying to get this up and running thanks.
