Dead time for stock injectors?

[HiSPL]

Does anybody know the actual dead time of the stock NA bosch injectors? Mine are from '88 LH2.2, but they are all the same I believe.

Injector dead time

Changing injectors to a 0-280-155-831 I can't seem to find published data for the injector dead time. Or voltage curve. I have heard some speak of switching from 2 squirts to 4 squirts and observing the change in AFR. Any guidance? Or links?

Looks like 0.950 is the accepted "good enough" time.

You can change the number of squirts per cycle and then dial your deadtime in so the AFR change is minimized. But then that's only at one voltage point. So then you have to do it at a lower and higher voltage point. It's a huge PITA. Or just do it at that one voltage point.
Though... Once you get the deadtime dialed in, it really makes swapping injectors without drastically changing the tune easy.

I just buy deka injectors with the data publicly available. It get's you close enough to say "F-it, that's good enough"

I upgraded from volvo white injectors to a set of Deka 80s. I entered the data in the required fuel calculator and burned it. Car will sputter a bit but won't run anymore.

Does that setting scale the VE table? Are there other settings I need to change when upgrading injectors? Cranking/ WAE/Priming settings need to change? (These are known good injectors btw)
