Look for the table "Ignition retard limit". Its set for -10 stock.

You need to also change the value in the table at 0x173e for 7/8 and 0x133e for 9.

Setting the value to:

220 allows -15°
237 allows -18°
255 allows -22°

Also from mrfred awhile back:

Not sure yet on what conditions these are, but here are the two tables for the 8859XX15 and the 9653XX06. They may both need to be set more neg for ignition to retard further under all conditions. Note that the max possible neg value is about -28 deg. Should be easy for people running newer JDM, EDM, and ADM ROMs to find the additional table by comparing the offset between the two addresses.

8859XX15:

<scaling name="IgnTimingECUa" units="deg" toexpr="61-x*90/256" frexpr="(61-x)*256/90" format="%.1f" min="-30" max="50" inc="1" storagetype="uint16" endian="big"/>
<table name="Ignition Retard Limit #1" category="Timing" address="205e" type="1D" level="1" scaling="IgnTimingECUa"/>
<table name="Ignition Retard Limit #2" category="Timing" address="133e" type="1D" level="1" scaling="IgnTimingECUa"/>

9653XX06:

<scaling name="IgnTimingECUa" units="deg" toexpr="61-x*90/256" frexpr="(61-x)*256/90" format="%.1f" min="-30" max="50" inc="1" storagetype="uint16" endian="big"/>
<table name="Ignition Retard Limit #1" category="Timing" address="2438" type="1D" level="1" scaling="IgnTimingECUa"/>
<table name="Ignition Retard Limit #2" category="Timing" address="173e" type="1D" level="1" scaling="IgnTimingECUa"/>

88570008-88570014, 88580013-88580015, 88840016, 88900006

<scaling name="IgnTimingECUa" units="deg" toexpr="61-x*90/256" frexpr="(61-x)*256/90" format="%.1f" min="-30" max="50" inc="1" storagetype="uint16" endian="big"/>
<table name="Ignition Retard Limit #1" category="Timing" address="2038" type="1D" level="1" scaling="IgnTimingECUa"/>
<table name="Ignition Retard Limit #2" category="Timing" address="133e" type="1D" level="1" scaling="IgnTimingECUa"/>

9417XXXX has only one ignition retard limit table:

<scaling name="IgnTimingECUa" units="deg" toexpr="61-x*90/256" frexpr="(61-x)*256/90" format="%.1f" min="-30" max="50" inc="1" storagetype="uint16" endian="big"/>
<table name="Ignition Retard Limit #2" category="Timing" address="173e" type="1D" level="1" scaling="IgnTimingECUa"/>

I have tested mrfreds addresses with 9653 and best I got was -10. With 9 (8858) I can get -20.

Also verified that the 173e in 94170015 doesnt go past -10. I added the following addresses and settings as I would in the IX-

0x173f
0x4300 (decel ignition cut limit)

Then I altered the EGR timing table and nothing. Unless I am having a super blonde moment, there is something else we dont have for the USDM stuff. It works in the IXs, havent been able to get any VIIIs to work.

Can't get my JDM 7 to go past -10 either.
This is whats defined in my 9055 XML.

table name="Ignition Retard Max Degrees - dec" category="Timing" address="173e" type="1D" scaling="Retarduint16"/>
<table name="Ignition Retard Max Degrees - hex" category="Timing" address="173f" type="1D" scaling="RetardHex8"/>
