Ignition Retard Limit
#181
Hey Todd,
Is it possible to get below -20 on the 25570100 (ceddymod) rom?
I can get mine to -20 but have seen Ceddy himself post on few forums that -27 should be possible.
heres the last few lines I used in the XML to get -20
<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="25813" category="Timing" type="1D" level="2" scaling="TimingMUT"/>
<table name="Ignition Advance Limit" address="25810" category="Timing" type="1D" level="2" scaling="TimingMUT"/>
</rom>

A question regarding retard with a GTA auto. My GTA shows -1deg of retard between gears at wot. Is it ign retard because of knock/shock?
I was thinking with spark retard, I could set even higher pres between gears and the retard time would cancel the shock
But I'm thinking it would make my gear shift time worse/longer if drag racing. Open to your thoughts!

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 to the map 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 still -10.
What am I doing wrong here.?

But yeah I do understand the point you are making and the risk of it.
