After searching and tweeking for the various maps additions below are the what I found to work.

These are what I have for 94170015:

<table name="Post Primer Enrich Decay #1" category="Fuel" address="3712" type="2D" level="2" scaling="EnrichmentAdj">
<table name="Engine Temp" address="67bc" type="X Axis" elements="9" scaling="Temp"/>
</table>

<table name="Post Primer Enrich Decay #2" category="Fuel" address="3722" type="2D" level="2" scaling="EnrichmentAdj">
<table name="Engine Temp" address="67bc" type="X Axis" elements="9" scaling="Temp"/>
</table>

<table name="Post Primer Enrich #1" category="Fuel" address="3732" type="2D" level="2" scaling="uint8">
<table name="Engine Temp" address="67bc" type="X Axis" elements="9" scaling="Temp"/>
</table>

<table name="Post Primer Enrich #2" category="Fuel" address="3742" type="2D" level="2" scaling="uint8">
<table name="Engine Temp" address="67bc" type="X Axis" elements="9" scaling="Temp"/>
</table>

<table name="Primer Cranking Enrich - First Pulse" category="Fuel" address="3810" type="2D" level="2" scaling="uint8">

</table>
<table name="Thermo Fan Duty" category="Misc" address="459a" type="3D" level="2" swapxy="true" scaling="Percent (128)">

<table name="Engine Temp" address="65a4" type="Y Axis" elements="12" scaling="Temp"/>
</table>

<table name="Thermo Fan Duty #2" category="Misc" address="553a" type="3D" level="2" swapxy="true" scaling="Percent (128)">
<table name="Conditions" type="Static X Axis" elements="3">
<data>On</data>
<data>Off</data>
<data>A/C</data>
</table>
<table name="Engine Temp" address="6c24" type="Y Axis" elements="12" scaling="Temp"/>
</table>

<table name="Ignition Trim vs Air Temp" category="Timing" address="41b2" type="2D" level="2" scaling="Enrich">
<table name="Air Temp" address="6c24" type="Y Axis" elements="8" scaling="Temp"/>
</table>

<table name="Ignition Trim vs Engine Temp" category="Timing" address="41a4" type="2D" level="2" scaling="Enrich">

<table name="Engine Temp" address="681a" type="X Axis" elements="8" scaling="Temp"/>
</table>

THESE SCALINGS MUST BE ADDED under <include>evo7base</include>

<scaling name="Enrich" units="Enrich Units" toexpr="x-128" frexpr="x+128" format="%.0f" min="-128" max="127" inc="1" storagetype="uint8" endian="big"/>

<scaling name="Percent (128)" units="%" toexpr="x/1.28" frexpr="x*1.28" format="%.0f" min="0" max="100" inc="1" storagetype="uint8" endian="big"/>

<scaling name="Percent (256)" units="%" toexpr="x/2.55" frexpr="x*2.55" format="%.0f" min="0" max="100" inc="1" storagetype="uint8" endian="big"/>

The Address was wrong. These seem to be correct.

<table name="Decel Fuel Cut Delay - Neutral A/C Off" category="Fuel" address="42bc" type="2D" level="2" scaling="uint8">

I found one area that needs fixed though.....

<table name="Ignition Trim vs Air Temp" category="Timing" address="41b2" type="2D" level="2" scaling="Enrich">
<table name="Air Temp" address="6c24" type="Y Axis" elements="8" scaling="Temp"/>
</table>

The "Air Temp" scaling calls for "Temp" which is engine temperature.

A scaling needs to be made for Air Temperature in order for this to be accurate.

This might work for Air Temp Scaling....

<scaling name="AirTempFactor" units="Fraction" toexpr="x/64" frexpr="64/x" format="%.2f" min="0" max="2" inc="0.02" storagetype="uint8" endian="big"/>

It is the scaling for the IX in the evo9base.xml

The final result will look like......

<table name="Ignition Trim vs Air Temp" category="Timing" address="41b2" type="2D" level="2" scaling="Enrich">
<table name="Air Temp" address="6c24" type="Y Axis" elements="8" scaling="AirTempFactor"/>
</table>


Just tried it and .....DOES NOT WORK

I played with the Decel Fuel Cut Delay and Decel Ignition Retard tables earlier. I set the fuel cut delay tables to "0" and used the ignition retard to remove all ignition advance, and tested the result while revving the engine while the car sat stationary.

I didn't really notice any difference, which surprised me.

I think the vehicle has to be moving....thus decelerating.....Just a thought.

Ok, I interpreted these applying to engine speed deceleration, but you're telling me that it is vehicle speed deceleration. If so, that changes things.

Yeah if you notice....let off the gas and decelerate with the vehicle in gear.....the O2 will go way lean, thus the injectors are cutting out.

Yes, generally OEM ECUs will take extra measures to keep the engine from stalling while the vehicle is moving to prevent a sudden loss of power steering and power brakes. I just didn't realize this is what we are dealing with here.

Takes about 1 sec of closed throttle for injector cut after WOT.

As C6 said, the units seem to be time-tics of about 10mSeconds (very roughly).

If that's the case and they're in units of time, how come when I take my foot off the throttle during cruise or decel situations my injectors seem to stay on almost indefinitely until I tap the throttle again and let off? It tends to keep me at a constant 12.5 afr during decel, until I the throttle is tapped, then it will cut the injectors. I haven't gotten to play with this table just yet, but I have a feeling that it's not really going to resolve anything for me.

I am pretty sure there is also a Load factor involved in the Decel Fuel Cut. I remember seeing a 1D adjustment that was Load related in the same subroutine when I found the Decel cut maps. I didn't check into it too much (I dont have Decel issues) but it looks to be a Load amount to be below before Decel Fuel Cut will activate.
