What does that knob do mister ?

[Richard L]

A couple of question first for more accurate answers:

1. Which version of HFS3 do you have?
2. What is the maximum duty cycle are you running at present (larger injector)?

[jondee86]

I have version HFS3-3.1

With 440cc/min injectors the max DC would typically be 90% and sometimes
a little higher. I have changed to 550cc/min injectors and reset the HFS3
jumper to the 1.25 scalar position.

As a side note, I had assumed that the larger injectors being 25% larger
would result in a 20% reduction in IDC. However, looking at the logs I have
made to date, it appears that the performance characteristics of the two
injectors are not the same, and simple proportion does not apply. So my
guesstimate of requiring 40% gain is now out the window !!
