We had a new high dollar engine ruined because of too rich FI washing cyl walls. It happened quickly, before we found someone who could set it up properly. Walls were scored, burning
oil. Had to send engine back for o'haul, and this time they got the right program in the computer, and all is well. EFI is not forgiving of learn as you go programing.
Get someone who knows the system to help you. Maybe send it back to factory for bench test.
