Hitting fuel cut - multiplier setting not working?
I've been having problems hitting fuel cut at the 'Fuel Cut Load x1' value, even though (I think) I've got the 'Fuel Cut Multiplier' setup to use 'Fuel Cut Load x2'.
Attached is what my values are set to. ROM is 90550701, car is Evo 7. Any ideas what I'm doing wrong?
This is what my XML looks like:

I was having some confusion over this recently myself, are you on sd? I believe you need to have the load cap fuel flow eliminator and load cap airflow setting to 0x9 if it's currently set to 2ba1... hopefully someone comes on to confirm though.
I set them to 0x9 rather than 2BA1. That predates the switch to SD but its never affected anything for me. The MAF load cap is 378.5 as I recall, so you shouldnt be near enough to that even if you were blowing through the 335 mark a little.

I assume 'load cap fuel flow eliminator' and 'load cap airflow' are tables in an SD rom or something, as I can't see them in my 90550701 XML?
Will try setting the load boost address to 3814 though.

Tried that, but still getting fuel cut at the 'Fuel Cut Load x1' value unfortunately 
This is what the XML looked like when I flashed the ECU:
Any other ideas from anyone? This is driving me nuts!
This is what the XML looked like when I flashed the ECU:
Code:
<table name="Fuel Cut Load x1" category="Global Fuel Settings" address="3814" Type="2D" scaling="LoadBoost">
<table name="RPM" address="56b6" type="Y Axis" elements="9" scaling="RPM"/>
</table>
this should sort it , should be 600D--->4000 not 4D00 and 3814 for address
<table name="Fuel Cut Multiplier" category="Global Fuel Settings" address="11ac6" type="2D" level="2" scaling="Hex16">
<table type="Static Y Axis" elements="1">
<data>To use "Fuel Cut Load x1" = 0x600D To use "Fuel Cut Load x2" = 0x4000 :</data>
</table>
</table>
<table name="Fuel Cut Load x1" category="Global Fuel Settings" address="3814" type="2D" scaling="LoadBoost">
<table name="RPM" address="56b6" type="Y Axis" elements="9" scaling="RPM"/>
</table>
<table name="Fuel Cut Load X2" category="Global Fuel Settings" address="3814" type="2D" level="2" scaling="FuelCutLoadX2">
<table name="RPM" address="56b6" type="Y Axis" elements="9" scaling="RPM"/>
</table>
<table name="Fuel Cut Load Trigger Delay" category="Global Fuel Settings" address="159a" type="2D" level="2" scaling="Time">
