how do I determine how many pulses to do per ms if i wanted to test it at 2,2.5,3,4,5,6,7,8,9,10ms to get and even line with a 750cc injector?

By experimentation. See how many pulses it takes to nearly fill your measuring cylinder. (The closer to full it is, the more accurate the reading will be.)

Thanks I'll do that. I thought there might be some kind of round about numbers to go by. Do you know anyone with the spreadsheet?

This is the one I made a few years back, if you enter the rough guess flow of your injectors it will calculate a suitable number of pulses for you.

Sample spreadsheet.

Look for instructions in one my previous posts. It's the numbers in the black box which are plotted and cell k4 has the calculation. Amend it as you see fit.

kind regards
