and run a pattern match search for these same tables. I will post back the xml if I find a match in 9653XXX6.
Can you can test the effect of changing these tablesa nd post back what you find?

Found a match in 96530706:

Code:

	!!!!! CORRECTION - This table is incorrectly defined. It is actually Air Density Compensation for Load And IPW.
<table name="Decel Fuel Cut Resume Enrich" category="Global Fuel Settings" address="38fa" type="2D" level="2" scaling="EnrichmentAdj">
	<table name="Engine Temp" address="69d8" type="X Axis" elements="9" scaling="Temp"/>
	</table>  

	<table name="Decel Fuel Cut RPM Offset" category="Global Fuel Settings" address="36dc" type="2D" level="2" scaling="RPM8">
	<table name="Engine Temp" address="69be" type="X Axis" elements="8" scaling="Temp"/>
	</table>

I'm sure the Decel Fuel Cut RPM Offset is right. I'm not sure the Decel Fuel Cut Resume Enrich is correct because the RPM settings are way different than the Evo 7. I'm going to test and see if these make any difference to the fuel cut off on lift. Will post back with results.

"Decel Fuel Cut RPM Offset"

is not a very accurate description of this table, it is the RPM at which decel Fuel-Cut is cancelled and fueling resumes.

Does tephra have a table for this? If so which one is it?

If Im coasting at lets say 5k rpm and let off the gas and coast to idle the injectors kick on before I get to idle. The eng starts rocking the car because it kicks on and off. What can I do to control this?

Yes V7 has the table. In 9653XXXX it's a 2D table called Decel Fuel Cut Resume RPM

Code:

<table name="Decel Fuel Cut Resume RPM" category="Global Fuel Settings" address="36dc" type="2D" level="2" scaling="RPM8">
  <table name="Engine Temp" address="69be" type="X Axis" elements="8" scaling="Temp"/>
 </table>

Use Decel Fuel Cut Resume RPM. I lowered mine to 100 RPM above my idle and it reduced the bucking.

Let me take a peek Acree and see if I can find the same table in 88590715. If not you'll have to change to 9653XXXX

Yep it's there in 88590715. It's the only occurance of the byte string in the whole ROM so its a good bet that it's correct. Check it all the same and post up if it works.

Code:

 <table name="Decel Fuel Cut Resume RPM" category="Global Fuel Settings" address="30FE" type="2D" scaling="RPM8">
  <table name="Engine Temp" address="6fde" type="X Axis" elements="8" scaling="Temp"/>
 </table>

Yep it's there.

There are a few temp axes with the same data in 94170715 so I'm not completely sure that the temp axis address is correct. I am sure that the RPM data is correct though. Check it out and post up if it works for you.

Code:

 <table name="Decel Fuel Cut Resume RPM" category="Global Fuel Settings" address="36dc" type="2D" level="2" scaling="RPM8">
  <table name="Engine Temp" address="67a2" type="X Axis" elements="8" scaling="Temp"/>
 </table>
