cold start enrichment table

I have a question: Wouldn't it make more sense to look at all these tables (however you call them — "Primer Enrich" or "IPW adder") with InjectorLatency scaling? Since they add IPW?
So could it be that "Start IPW latency " is the latency that's used when the car is started and depending on temp more latency is added to it (or to regular latency table, since MrFred said this table is only called on Evo 7's) from "start IPW by temp correction" aka "Primer Enrich"?
I'd post some screenshots, but my laptop isn't connected to internet right now...

Anyone find the actual correct cranking IPW adder table for 96530006?
I'm finally converting over from 96940011 but I really need a properly defined table for 96530006 for E85 cold starting not to be an issue.
Currently I have this:
Compared to the def for 96940011 it seems wrong:
Also, has anyone found the proper "Base Low Coolant Temp Timing Trim Map #1" and "Percent Low Temp Timing Trim vs Coolant Temp" for 96530006?

I think gear head has has got it in his evo 8 xmls that he made up for me:

razorlab, cold start issues on E85? How can you have those....you live in cali! 
I've had *amazing* results on my car with FIC 1050's on E85. It is also right around 5'F here lately. 
One thing I have noticed with the percentage tables is that zeroing them out was almost too much. A few of us here up in the north have reverted to about half of the stock values for a nice medium, the car seems to run better when it's 'that' cold.
+1 for the maps you're asking about though, it would be nice to at least have them if I need them ever

That table should only be for the first pulse of fuel. It wont do anything after the motor has actually fired up. The smaller tables (should be 2 of them in that rom), are the ones that should work after the motor is running.
For 96530006 they are at 3732 and 3742. It looks like there are 2 decay maps as well at 3712 and 3722. Not sure what conditions determine which gets used, but try adjusting both.

Regarding the Post Primer Enrich and Enrich Decay 2D maps, why do we have two (#1 & #2)?
In fact, I notice we have a #1 and #2 for several other maps (e.g. Open Loop Load) and a #1 and #4 for maps like Wastegate Duty, and I am unsure as to why. Anyone?
Lastly, do the "Water Temp Enrich Starting" and "Water Temp Enrich Running" tables not seem somewhat redundant in function to the Primer Cranking Enrich and Post Primer Enrich? Anyone know the difference?

Thanks in advance.
I put all the stock values back for Cranking Primer (First Pulse) table yesterday night and the car had a really hard time starting up in the morning. I had cold start problems before too... until the values were changed. The table looks different than my old 96940011 ROM, but it seems like that table does help.
