Question pretty much sums it up? What have you used these alternating plots to accomplish with your FIC install?

Thanks in advance for your replies.

 

In case anyone decides to look. I plan on using the a channel to convert my UEGO (no digital readout) to 0-1 for the sole purpose of reading it on a cheap AF gauge. While running the software and data logging i'll be able to see it in high resolution. I think I can just splice the UEGO output into the AUX and A channel inputs.

 

One cal for gasoline and one for E85. It turns out to be pretty easy to do the switch once the calibrations are in place. I drain the tank when I do it but if the tank was pretty low and I filled up with a other fuel I could just switch cals and be close enough to run just fine.
