Name that Map (Purge Duty)
Hello everyone, thanks for a great forum and the loads of info on it.
I've been working on the older H8 ecus, these maps are from a DSM ecu.
I have almost all the 3D maps defined, but these last couple have me stumped.
The code leading up to them test MAF Hz at 50hz and 69hz, and have a bunch of bit tests to decide to use the 7x10 set or the 10x10 set.
They are close to being the inverse to each other.
Has anyone seen any maps like these before? Any ideas what they could be for?
Thanks much.

They wont. 
Ceddy is quickly showing himself to be our resident H8 guru at dsmtuners so if he doesn't know what something is then likely the rest of us don't either. The hope is that the evo ecus and the H8 ecus seem to be very similar, we even have lean spool even though it is disabled by default.

This is the tables in there natural form, I had them "swap x y" before.
I will have to follow them farther into the code to see where they end up.
I never thought of the Purge Solenoid. That only operates at lower rpms(less then 4000) if I remember correctly. The two tables could possibly be min and max duty cycle?
A lot of the DSM maps are near exact copys of the EVO maps, guess its not the case with these ones.
Thanks very much for everyones help and insights.

for 88590015 they look alike, but I do not know the scaling.
Code:
<table name="Purge control #1" category="Purge" address="479b" type="3D" level="1" swapxy="true" flipx="true" flipy="true" scaling="Hex8"> <table name="Load" address="74fa" type="X Axis" elements="10" scaling="Load"/> <table name="RPM" address="74c6" type="Y Axis" elements="7" scaling="RPM"/> </table> <table name="Purge control #2" category="Purge" address="485d" type="3D" level="1" swapxy="true" flipx="true" flipy="true" scaling="Hex8"> <table name="Load" address="74fa" type="X Axis" elements="10" scaling="Load"/> <table name="RPM" address="74c6" type="Y Axis" elements="7" scaling="RPM"/> </table> <table name="Purge control #3" category="Purge" address="47ed" type="3D" level="1" swapxy="true" flipx="true" flipy="true" scaling="Hex8"> <table name="Load" address="74fa" type="X Axis" elements="10" scaling="Load"/> <table name="RPM" address="75b8" type="Y Axis" elements="10" scaling="RPM"/> </table> <table name="Purge control #4" category="Purge" address="48af" type="3D" level="1" swapxy="true" flipx="true" flipy="true" scaling="Hex8"> <table name="Load" address="74fa" type="X Axis" elements="10" scaling="Load"/> <table name="RPM" address="75b8" type="Y Axis" elements="10" scaling="RPM"/> </table>

They even appear to be present in X (53040010)

Thanks very much Acamus.
I knew there was probably similar maps, mitsu likes to recycle their code.
May I ask why Tephra said "flipxy" before, and you have the flipx and flipy selected?
I tried going through the map lookup routine, to see if the axis are referenced backwards, I didn't see anything obvious, but the lookup routines confuse me most of the time..
