Re: EBL flooding during cold cranking...
The choke tables aren't used during cranking. Just the VE table and the three crank tables shown. The crank PW multiplier table is for the crank->start->run transition. So no need to change it (for this issue).
The crank prime PW table doesn't look too rich. But then again I don't know what ambient temperatures we are talking about. That table can be zeroed if desired.
Which leaves the crank AFR table. Increase the AFR in those areas where it floods on a cold crank.
Note that holding the go-pedal on the floor during cranking is a clear flood mode.

That is in the 4° to 10° C range. Lean the cranking AFR starting with say .75 AFR higher and taper into the real cold area. Note that sooner or later it can get lean enough that it may not start. So be aware of that (just back up a tune/BIN).
