if i remember right you take the high and low slope numbers that are in the chart and mutiply them by 3600 because they are lbs./sec and you need to convert them to lbs. /hour. this will give you a starting point you will still have to fine tune low slope to your combination even if you use somebody elses numbers. i had to anyway. use the breakpoint number as is .that is how Chris explained it to me. that is how i would go about it.

Correct.
High slope: 0.020877 x 3600 = 75.1572lbs
Low slope: 0.028183 x 101.4588lbs
breakpoint: 0.0000242100

Thanks for the help guys. I understand now, and hopefully someone else can use this data in the future when searching.

another thing you have to be careful of, if you set your maf numbers in metric make sure to switch back to english setting when you input slope numbers. took me a little head scratchen to figure that one out. wouldn"t run went back to slope numbers totally different than what i entered! lol

I'm going to pull this back up...I have to enter in injector data into a table that's labeled as Opening Time (ms) vs Battery voltage.

The battery voltage axis has odd values:

8.7
10.4
12.2
13.9
15.6
17.4
19.1
20.9

Not quite sure what to put in for values for the corresponding Opening Times?

Can anyone help me out here?

They don't have the same slope, so not really sure how to figure it out...should I just guestimate?

Thanks,

Chris

dont really understand what you are asking. if you are trying to enter injector slopes and breakpoint, sounds like you are in the wrong spot.

I should've mentioned this is for a BigStuff3. There is a table labeled Injector Opening Time. Down on the bottom there is the battery voltage (which cannot be changed) and the input boxes are the opening times (ms). The numbers I listed above are the battery voltages...the input numbers listed for the siemens-deka offset times do not match.

My questions are: Are those the numbers I need? If so, how would I get them dialed in?

If your using a tuner such as QuarterHorse or Tweecer the breakpoint would be converted to 2.421 as the input value for breakpoint aka FN389.
