Dumb question...Does FAST XFI come with instructions on how to use it's functions and what they do? I'm trying to lean out my idle fuel, it's pig rich on E85. I was using Eric's SD chip and did well with it and it had some easy to follow instructions and what functions changed what etc, so I'm learning FAST now.
I purchased the FAST from CAL @ Hartline but prefer not to bug him every time I have a question if there are instructions out there.
