When dialing in your injectors you usually wanna stay in Closed Loop
That is gonna require a very light load

or
You will slip into Open Loop
You are gonna want to go easy ... very easy ... on the go pedal
I used to climb a slight hill in 4th on the freeway so I could get some
high pulse widths
I'd start the hill at about 50mph and usually between 65 & 70 I'd
slip into Open Loop
