After quite a bit of reading and studying of the how-to's on this, I went through the voltage off-set adjustment procedure. As near as I can tell, I did everything as prescribed. At first, I came up with an adjustment of over 3.3 to get the histogram to average out at 14.7! See attached picture.
So, I turned off the LM-1, powered it back on and tried it again. That time I came up with 9.85 which seems more reasonable.
My question is: When I change the LM-1 graph back to 0 to 5 volts, shoudln't the AFR histogram show what the LM1 is reading now? Mine still reads 14.7.
WB-O2 sensor is sitting in open air.
Thanks for any help,
