Coldstart ignition map for 96530006
96530006 Coldstart ignition map, Low Coolant Temp Timing Trim Map is incorrect!
Code:
<table name="ColdStart Ignition" category="Timing" type="3D" level="1" swapxy="true" scaling="Timing" address="61c9"> <table name="Load" type="X Axis" elements="19" scaling="Load" address="6910"/> <table name="RPM" type="Y Axis" elements="20" scaling="RPM" address="68de"/> </table>

Interesting, I have that 3D map down as an "unknown" ignition map, with a note that it might be related to cold start. I have a related control map along with it defined as:
Note that I didn't personally locate either one; I believe Mattjin did. I haven't traced the code involved to verify it does anything at all. 
Code:
<table name="Ignition Unknown Control" category="Timing" address="61b6" type="2D" level="2" scaling="Percent (255)">
<table name="Engine Temp" address="6a36" type="Y Axis" elements="8" scaling="Temp"/>
</table>

I didnt find the maps for this particular rom, but you have the wrong addresses. These are the two maps you should have.
For 96530006:
<table name="Low Coolant Temp Timing Trim Map" address="3ff5">
<table name="Engine Load" address="6910"/>
<table name="RPM" address="68de"/>
</table>
<table name="Percent Low Temp Timing Trim vs Coolant Temp" address="41dc">
<table name="Engine Temp" address="6a36"/>
</table>
These are using the latest base files, but if not you can just pick out the addresses. The map you refer too actually looks alot like an anti-lag map!

I have logged the ignition at coldstart and it is -5 as shown on that map, that "Low Coolant Temp Timing Trim Map" at address 3ff5 is fuel map used at closedloop.
