Uh....It is actually. As far as I know. Cranking generally happens right at the 100kpa (atmo) range, and I'm pretty sure cranking is just an added percentage of the fuel table. Plus a lot of other math.
But I could be completely wrong.

msq and log attached.. (although i havent read much about logs and i have no idea what to make of it)
also a video of startup. coolant was probably ~55* outside temp was low 40s.

I guess I did not know that the fuel table wasn't factored in during startup.. but it seems like when I changed the table it affected startup but maybe that was my imagination
thanks for your help dudes. I do appreciate it because I've read all I can stand to read on this and still can't figure it out. I will be glad to paypal $10 beer money to whoever makes it right.
while you're having a look at my msq.. my injector ccs are set at 240, but this page Fuel Injectors - Miata Turbo FAQ says 254 in the pic, then 265 in the text below.. that was set by rev so I didn't mess with it.. was he just being conservative? also.. is it 254 or 265?

so my WUE, ASE, and cranking pw are now a lot lower/normal. The weird thing is nothing I do makes it better/worse. It always just starts like crap (cranks for like 3-5 seconds, small sputter, then catch) and runs fine once it catches. There must be some setting I'm overlooking. What part of my fuel table exactly affects startup? I'd guess the "below 500" column.. but does it factor in my idle rpm somehow?

dammit im having a hell of a time getting a log.. when i took an engine log during startup and tried to view it it says "no time column available".. i'm not trying to get pissed but my schedule doesn't let me spend much time messing with my car and i've spent all my patience trying to figure out how to fix my startup myself..
so tomorrow i'll try to figure out what i'm doing wrong with logging. in the meantime can anyone tell anything im overlooking from my msq (& video)? by this point i've tried everything from way too little fuel to way too much fuel and everything in between and the tune i posted is the best i can come up with.. it's driving me pretty crazy.
