Can't remove boost cut
For some reason I'm unable to remove the boost (fuel) cut in an Evo7 GT-A! I inserted all 319s under boost limit but to no avail, the cut came at 19 psi of boost. I even tried inserting a big number under boost delay timer but still the it cut at 19 psi! Am I missing anything, or could it be an error in my xml definition?

I'm going to see about confirming the location of the fuel cut region.

Found what i think is the fuel cut load table
There are two of them probably the 1-3 gears and 4-5 gears like the rest of the maps.
Map 1:
3A48
Map 2:
3A58
<table name="Fuel Cut 1" category="Fuel" address="3a48" type="2D" level="1" scaling="Load8">
<table name="RPM" address="5a70" type="Y Axis" elements="9" scaling="RPM"/>
</table>
<table name="Fuel Cut 2" category="Fuel" address="3a48" type="2D" level="1" scaling="Load8">
<table name="RPM" address="5a70" type="Y Axis" elements="9" scaling="RPM"/>
</table>

Could you investigate the following address: 173e (1d table) this should be the 'timing retard limit' which would be useful setting up some sort of anti lag.
Thanks

Did you get the chance to check that timing retard address?
On the 80700010 thread, Tephra posted the same addresses for boost limit tables but with different rpm addresses than yours (6266) & they seem to be working fine.
Thanks again

I'll probably check on it when i get back to work on monday. Consider just trying the values out in the meantime. I think the default retard limit for most evo's was -10 degrees or so.
I pulled the rpm axis out of following the map Y axis i'm sure one of them are correct tephra probably knows the rom better than i do trust his judgment on this.

Boost limit tables with the new addresses worked fine & I was able to remove boost cut! I set ignition retard at -17 for testing & inserted some -ve timing in low load areas but still didn't get any bangs I'll try -20 ignition retard the next time. I've been getting a lot of phantom knock confirmed by detcans & non of the 80700010 XMLs I have contain knock control tables.
A friend provided the following addresses for knock control:
<table name="Knock Multiplier - Low RPM" category="Knock Control" address="177a" type="1D" level="1" scaling="uint16"/>
<table name="Knock Multiplier - Mid RPM" category="Knock Control" address="24a8" type="1D" level="1" scaling="uint16"/>
<table name="Knock Multiplier - High RPM" category="Knock Control" address="21dc" type="1D" level="1" scaling="uint16"/>
<table name="Knock Adder - Single Gain" category="Knock Control" address="177c" type="1D" level="1" scaling="uint16"/>
<table name="Knock Adder - Triple Gain" category="Knock Control" address="1780" type="1D" level="1" scaling="uint16"/>
Do these look right?
