Injector Duty Cycle

How do you measure/log it? I have an HTA37r Buschur kit with PTE1000cc's and a single Walbro. I'm afraid I might run out of fuel on higher boost. Of course I'll know when I can't control the fuel anymore...

I have Mitsulogger and EVOSCAN.

EDIT: I did a quick search and came up with a bunch of threads. I still don't understand...there are so many formulas out there and I've seen posted many times that EvoScan's formula is crap. I know how to modify the formulas but what should I use?
Also, everyone knows that the newest EvoScan cannot log AFR's so I am using Mitsulogger as my primary logger. It doesn't seem to have something to calculate out IDCs though..unless I just don't see it. I'm a noob at this so I don't know how the data from other things go into the calculation of IDC. This is just my learning curve.

rpm x IPW divided by 1200 equals IDC

Or use this:

Yeah I thought of buying that twin Denso pump setup with the anodized aluminum housing. Expensive.
