I also 100% believe there is a Fuel vs Engine Temp map, but I have to say that I have absolutely every table that exists in the rom and none of them seem to do this function. There is a certain look of the table that you would expect.... it would have to be larger numbers for cold and smaller numbers for hot. The same as you generally see for the cranking and post start enrichments. Every table that has this appearance does not trim the fuel with engine temp.
Very very confusing, I must say.

I'm not sure what you mean by you did it as a function of engine temp rather than cranking enrichment?
I will try logging as you said - I log it to screen and watch while its cranking and then go back after to review the logs closer. No matter the value in the table my ipw is always around 4 on cranking, while my table shows something totally different.

You have something wrong with your car or your ROM. The injectors are fine.
Travis after logging your car this weekend your startup IPW looks like crap. It is jumpy and even has a dip in it. Also for some unknown reason your car went to 1.3xx volts of battery voltage on two consecutive starts. Here is a log of my car starting up fine during the exact same "warm start" of 50-60deg C you are having issues with.

So I just realised that I never posted the tables for 96420008 (realistically 7 as well).
Here are the 04 specific parts of the code-
<table name="Start IPW by Temp correction">
<table name="Water temp" address="6904"/>
</table>
<table name="Start IPW by RPM correction">
<table name="RPM" address="67ee"/>
</table>
For some reason in my old version of V1.30 its incomplete in the xml (yet still works?) Here is the rest of the data that you'll need-
scaling- IPW McSec
<scaling name="IPW mcsec" units="mcSec" toexpr="x*432/1000" frexpr="x/432*1000" format="%.0f" min="0" max="255" inc="1" storagetype="uint8" endian="big"/>
for Vs. Water temp the address is 3810 and there are 11 elements
for Vs. Rpm the address is 3822, there are 8 elements and the scaling is:
<scaling name="Correction Co-eff" units="mcSec" toexpr="x" frexpr="x" format="%.0f" min="0" max="1000" inc="1" storagetype="uint8" endian="big"/>
Sorry about the lack of follow through guys

I can't find a final answer on what the Defs are for this rom. It looks like all 4 of those addresses pull up the same table. Has anyone finalized which address is which for 96530006?
Is it this?
or this?
Is it this?
Code:
<table name="Cranking Enrichment IPW Adder (Main)" address="3732">
<table name="Coolant Temperature" address="69be"/>
</table>
<table name="Cranking Enrichment IPW Adder (Unused)" address="3742">
<table name="Coolant Temperature" address="69be"/>
</table>
Code:
<table name="Cranking Enrichment IPW Adder (Main)" address="3712">
<table name="Coolant Temperature" address="69be"/>
</table>
<table name="Cranking Enrichment IPW Adder (Unused)" address="3722">
<table name="Coolant Temperature" address="69be"/>
</table>
Here is what I have:
Code:
<table name="Cranking Enrichment IPW Adder (Main)" category="Fuel" address="58d0" type="2D" scaling="TimeInjCranking"> <table name="Coolant Temperature" address="69d8" type="Y Axis" elements="9" scaling="Temp"/> </table>

Being a dumb noob... On the tephra mod 7... where do I adjust the Cold start enrichment table? my problem is not being able to start on the cold weather, I'm talking 40 F and below. I have an 03 evo8 with 1000cc injectors.
