Hi guys,
I have a JDM Evo 8 with the 96530706 tephra ROM.
I am trying to retard my timing beyond the stock lower limit (-10 degrees). I have added the following patch code to the 96530706 tephra XML.

<scaling name="TimingMUT" units="degrees" toexpr="x-20" frexpr="x+20" format="%.0f" min="-20" max="60" inc="1" storagetype="uint8" endian="big" />


<table name="Ignition Retard Limit" address="1813d" category="Timing" type="1D" level="2" scaling="TimingMUT" />
<table name="Ignition Advance Limit" address="1813f" category="Timing" type="1D" level="2" scaling="TimingMUT" />

In the tables I changed the ignition retard limit to -20. Went ahead and changed the timing in the respective timing cells to -20 as well. Flashed the ROM. Logged using evoscan. The lowest timing retard that I can see is in those cells itstill -10.

What am I doing wrong here.?

I did a search and all the results are telling to do the above steps only.

Please help me and thanks in advance.

 

You are doing nothing wrong. I was never able to get below -10 on 9653XXXX either.

 

What r u trying to do ? Launch control or anti lag ? I got jdm rom n xml code with both mods that i tested. Timing goes down to -20 when down shift, antilag activation or in launch control mode my email is vophcu08@gmail.com if u wanna send me some donation for my time doing all the research n testing. I can send you the xml n rom
