I am using the Innovate MTX-L simulated narrow band output into C16 (I feed that and the WB signal through a toggle switch, which works great BTW). Occasionally, I will datalog narrow band in ECU Control to see if I am hitting correct stoichiometric close loop operation in some cells. However, the values for narrow band AFR range from 6-50, so it is a different scale, can someone tell me how this relates to 14.7 stoichiometric values? I recall seeing it somewhere on PGMFI, but I can't find the thread...

thanks!

If I remember correctly, the 0-50 value is scaled to match 0-5 volts. I'm not sure what the actual point of showing that number vs. real voltage is but it is an option. I will check this week to be 100% sure...
