in order to get the injector dead time measurement, you do a flow test with a graduated cylinder then enter the numbers into an excell spreadsheet, once you get your final dead time and flow numbers you plug those in to Tunerstudio. from there you will have tunerstudio calculate required fuel which gives you all your cranking and initial start fuel settings.
a video i made a while back on doing the injector dead time testing.

the stand i have in the video is just something i whipped together out of some MDF and have the rail attached with zip ties to it
the graduated cylinder is a 100 ml glass graduated cylinder with 1 ml increments, i paid about $15 for it off ebay.
