For the USDM Evo 9, yes. Not sure about the other ROMs. Mattjin probably found the decel fuel cut delay tables first for the Evo 7 GTA ROM and then took educated guesses at finding the tables in other ROMs.
Looking forward to your findings.
For 9417, 9653 and 8859....... to bad I cant disassemble

I'm not a tuner in fact the only reason I'm doing this is because my ex-tuner gave me back my car with a lot of throttle hang and does not want/know fix it
You should also know that I've read my 1st ECU rom no less than 5 days ago and reading forums since then is my only experience in ecu-tuning, I have absolutely no idea of what I'm doing.
So take those tables with extreme caution, I found them by taking guesses and calculating the address from other tables.
I just tried various addresses until the results matched screenshots in the Merlin evo tuning guide and other screenshots found on evom, that's how scientific it was
This said tables that "seem right" for the 88580013.xml
Fyi I apparently have the tephra v7 88580714 rom on my car

I personnally won't modify them and reflash my car until I got confirmation that they are right !

Code:
<table name="Decel Fuel Cut Delay #1" category="Fuel" address="3d92" type="2D" level="2" scaling="uint8"> <table name="Engine Load" address="6fd0" type="Y Axis" elements="7" scaling="Load"/> </table> <table name="Decel Fuel Cut Delay #2" category="Fuel" address="3da6" type="2D" level="2" scaling="uint8"> <table name="Engine Load" address="6fd0" type="Y Axis" elements="7" scaling="Load"/> </table> <table name="Decel Fuel Cut Ignition Retard" category="Fuel" address="3dc6" type="2D" level="2" scaling="Timing"> <table name="Engine Speed" address="6fa8" type="Y Axis" elements="10" scaling="RPM"/> </table>

I took some time to look at the 9417 and 9653 ROMs, and the "decel fuel cut" tables in these ROMs are also ISCV demand tables. For those of you that have used these tables to successfully reduce the throttle hang, did you decrease or increase the values in the table(s)?
Decrease

I think i have resolved my issue, well made it alot better anyway in my 8 with 9653 ROM
I zeroed the below tables
- ISCV Demand RPM Adder [rpm > 4500, load > 170, speed > 12 mph]
- ISCV Demand RPM Adder (Moderated by Baro, IATS) (FFFF6EA8) (sub_204B6) [sub_1EFC0]
And made my Decel Fuel Cut all the same as table 2, the car drives much better now.

decel fuel cut tables
I have a 05 MR USDM Evo 8. Rom ID 96940011. I really need to stick with this version rather than 9653XXXX. But I desperately need the decel fuel tables and addresses so I can eliminate the nasty throttle hang at 4000. Already did the clutch switch test, switch is fine.
'Ive asked before in several threads, more than 6 months of asking, been ignored by everyone, but am asking again. Really need the tables for 96940011
Thanks very much
