I'm not seeing that one at all.
I'm using VX_V6_SC_$A5K_Enhanced_V1.3e
And looking at this table

OK, been looking at the VT V6 SC $A5G XDF which has the above table, comparing the data to the VX V6 SC $A5K XDF and that table seems to labelled as the table I referenced in my post above?

ok didn't know which A5 you both were refering to, have fixed and updated VX VY S/C with Crank and Cold start Items.

The1 are you saying this table...
Cold Engine - Temp Dependent AFR Change V's Coolant - P/N
&
Cold Engine - Temp Dependent AFR Change V's Coolant - Drive
needs to be adjusted for Deka injectors as that seems to me more a running fuel adjustment not cranking?

cranking is obviously cranking, the cold tables ive had to adjust sometimes as it cranked and fired ok, but then stumbled lean or rich for the first few seconds, especially when cold under 30c temp the dekas dont seem to help combustion. Along with that adjusting EOI so the fuel doesn't sit on the cold valve so long helps to.

So I now have the crank table better but as The1 suggested there is an issue with injectors when cold not hitting target afr!
Is there a table that adjusts coolant temp based injector settings as fudging the afr table doesn't seem right to me as I like things to hit target & not fudge around as best possible.
Also with those cold afr tables added is it the correct calc as it can go to 200% but really shouldn't 100% be max?

if its a multiplier it can be as big or little percentage as you like ?

Not sure?
I'm talking about the cold afr tables that were added to the $a5k xdf which in the coldest range the hex value is around 7x & in its calculated value is around 99.x% so if you made it 8x it would be over 100% & I didn't think it would be correct?
