Okay, so comparing values leads me to believe the following:

#3 (Boost Enhancement Enrich/Enlean) is at 3ff5, and is referred to in the 96530006 XML as "Low Coolant Temp Timing trim". XML in 96530006.xml:
Code:
    <table name="Low Coolant Temp Timing Trim Map" address="3ff5">
        <table name="Engine Load" address="6910"/>
        <table name="RPM" address="68de"/>
    </table>
XML in evo7base_20081101.xml:
Code:
        <table name="Low Coolant Temp Timing Trim Map" category="Timing" type="3D" level="2" swapxy="true" scaling="TimingTrim8">
                <table name="Engine Load" type="X Axis" elements="19" scaling="Load"/>
                <table name="RPM" type="Y Axis" elements="20" scaling="RPM"/>
        </table>
#4 (Boost Enhancement Adv/Ret Map 2) is at 3e6d, and is referred to in the 96530006 XML "High Oct EGR-Enabled Advance". There is a partner table that goes with it, named "Low Oct EGR-Enabled Advance" (this table is all zeroes), located at 3ce5. XML from 96530006.xml:
Code:
    <table name="High Oct EGR-Enabled Advance" address="3e6d">
        <table name="Engine Load" address="6910"/>
        <table name="RPM" address="68de"/>
    </table>

    <table name="Low Oct EGR-Enabled Advance" address="3ce5">
        <table name="Engine Load" address="6910"/>
        <table name="RPM" address="68de"/>
    </table>
XML from evo7base_20081101.xml:
Code:
        <table name="High Oct EGR-Enabled Advance" category="Timing" type="3D" level="2" swapxy="true" scaling="Timing">
                <table name="Engine Load" type="X Axis" elements="19" scaling="Load"/>
                <table name="RPM" type="Y Axis" elements="20" scaling="RPM"/>
        </table>

        <table name="Low Oct EGR-Enabled Advance" category="Timing" type="3D" level="2" swapxy="true" scaling="Timing">
                <table name="Engine Load" type="X Axis" elements="19" scaling="Load"/>
                <table name="RPM" type="Y Axis" elements="20" scaling="RPM"/>
        </table>
Addresses for the main tables are the same for both 96530006 and 94170015, although I think the axes are different (just use the axis addresses from the 9417 timing tables). The results the OP is seeing seem to jive with the apparent functions of these tables.

I'll post up the XML address when I get home.

I added those EGR tables. They appear to be exactly the same as the Antilag tables.

So it gives you the fuel tables also?

no mine are scaled to show timing.

Evoryder: There's no possible way that the "Boost Enhancement Enrich/Enlean" fuel table you have defined is actually a fuel table; it's definitely timing. An easy tip-off is the fact that it's 20x19. rather than 15x18, but it's only referenced in the ignition routines in the code.

Applaudd: I don't think those tables have anything to do with factory antilag. I seem to recall that there was a thread about those being mis-defined, but can't find the definitive reference now.

I figured that was the case. I recall this same discussion a while back but I wasn't sure of the exact details.

The anti-lag tables are more for cold start than for anything related to anti-lag.

For those with cold start issues, zero out these anti lag tables and the amajority of the cold start problem should go away. It will, however take a little longer for the car to warm up to operating temperature.

As promised my XML for the "boost enhancement" portion:

Code:
<table name="Boost Enhancement (Anti-lag) Table" address="39b6">
		<table name="RPM" address="6654"/>
	</table>

	<table name="Boost Enhancement Adv/Ret Map 1 (Anti-lag)" address="3ce5">
		<table name="Load" address="66f4"/>
		<table name="RPM" address="66c2"/>
	</table>

	<table name="Boost Enhancement Adv/Ret Map 2 (Anti-lag)" address="3e6d">
		<table name="Load" address="66f4" scaling="Load"/>
		<table name="RPM" address="66c2" scaling="RPM"/>
	</table>

	<table name="Boost Enhancement Enrich/Enlean (Anti-lag) Map" address="3ff5">
		<table name="Load" address="66f4"/>
		<table name="RPM" address="66c2"/>
	</table>
If it is a timing map when it looks like an extended fuel map so be it, I just want to help others that may have had the same/similar issues.

In my evo 7 base the boost enhancement enrich/enlean could either be a Fuel / Timing table it just has the the incorrect# of cells/elements.

Code:
<table name="Boost Enhancement Enrich/Enlean (Anti-lag) Map" category="Fuel" type="3D" level="1" swapxy="true" scaling="AFR">
        <table name="Load" type="X Axis" elements="19" scaling="Load"/>
        <table name="RPM" type="Y Axis" elements="20" scaling="RPM"/>
I changed the elements in the evo7 base to reflect a fuel map, maybe Tephra,mfred or whoever can chime in to find where "3ff5" goes? I'm also wondering why the earlier attempts to disabled what was thought were the Egr tables did not disable all functions of the egr/anti-lag.

SCALED @ 19X20 VALUES AT 14.7


SCALED @ 18X15 VALUES AT 14.7


SCALED @ 19X20 DEFAULT VALUES



SCALED @ 18X15 DEFAULT VALUES


<--- sorry back ON topic

This definitely helps driveablility. But on mine I also had to disable the EGR cel as it was thrown after driving for a little while. The only issue I am facing is the cold starts, Car will start fine, shoot to 2k for a second then slowly come down to normal warmup idle(1400 rpm). But as it is warming up, if the throttle is blipped the smallest amount, then the car will shoot back up to 2k. Anyone know why?

Mine does the same thing, I think it would be an idle stepper adjustment. Going to log my cold start.
