English term or phrase: Volt comp
5.)Set the dead time (volt comp) in this area at a nice low even number like say .200ms and take note of the AFR (you can tune the AFR for 14.7 or whatever you want, it's just a baseline for now to use as refference

6.)turn on enough accesories/lights to move the volt comp/dead time cell to it's next cell over (usally in a stand alone it will be a graph ov volts from 16 down to 6 or 8 volts in small increments) We are aiming for 13.6 or whatever your operating temp highest volts are - if 13.6 was our average peak, load the electrics enough to bring it to say 12.8/13.0 whatever is the next lowest volt cell

Then as you near the lowest end of the scale (say 8 volts) raise the values a bit more, say we were adding .150 per volt and did that from 12.8 volts down to 10 volts, well at anything below 10, make the value you add by increase by say 50% so .150 * .50 = .075... Then .150 + .075 = .225ms, and there you have it, no need to ask, post, use other's numbers to only have it still not be right etc..

what dead times really only do is make sure the injectors are opening enough to get the amount of fuel needed to keep the AFR's in check when the volts drop since they will taek longer to open with less volts... now hook your fuel pressure vac line back up and enjoy. As for the values when FP rises wtih boost, no worries, that's what your pulsewidth takes care of, like i siad, most older systems and some newer ones don't even call it dead time, it's just voltage compensation mapping and in boost you have higher bolts at higher RPM's (at least your regulated peak of say 13.6) and dead times don't make a difference, you just change the open tiem on the injector overall.. this is really as i said a way to keep things operating and the egnienr unning at ngiht with lights on, or to keep the engine from stalling out due to lack of fuel should there be a sudden drop in vots from an electrical draw on the system at night at idle and low RPM cruise
