EFI is fun stuff and I really enjoyed learning about it. Pretty much any of Greg Banish' books are great reads, I would particularly recommend this one if you want some good reading material.
Anyway, so this means that your ECU was commanding that duty cycle. So your fueling table has milliseconds of open time but each engine cycle is only so many ms long. The formula is (RPM/60)^-1 for the seconds of each revolution.
Is this data from your engine? Cause at 5800 RPM you have 0.0103 seconds or 10.3 milliseconds per cycle. Your commanded duty cycle was 16.3 ms so it was actually pushing for over a 158% duty cycle! I figure it probably just only calculates a range of up to 120% then pegs it cause after that you know you have an issue.
Are you running a closed loop control on this engine? That is, does the EFI change the amount of fuel to keep the air fuel ratio in the right range?
