*Better* fix for P0300

Hi Peeps,

Recently the number of P0300 problems has become serious enough for me to investigate properly. Thanks to MrFred for providing the disable, however as acknoledged by him it affected too much code and without knowing exactly what else was being disabled I felt it was reckless to use it.

Thusly may I present a couple of maps that affect when the ECU decides to throw P0300:

530400010:

Code:

<table name="P0300 #1.1" category="Misc" address="56703" type="3D" swapxy="true" scaling="uint8">
<table name="Load" address="611ec" type="X Axis" elements="16" scaling="Load"/>
<table name="RPM" address="611d0" type="Y Axis" elements="11" scaling="RPM"/>
</table>

<table name="P0300 #1.2" category="Misc" address="567bb" type="3D" swapxy="true" scaling="uint8">
<table name="Load" address="611ec" type="X Axis" elements="16" scaling="Load"/>
<table name="RPM" address="611d0" type="Y Axis" elements="11" scaling="RPM"/>
</table>

52680022:

Code:

<table name="P0300 #1.1" category="Misc" address="566ff" type="3D" swapxy="true" scaling="uint8">
<table name="Load" address="611b0" type="X Axis" elements="16" scaling="Load"/>
<table name="RPM" address="61194" type="Y Axis" elements="11" scaling="RPM"/>
</table>

<table name="P0300 #1.2" category="Misc" address="567b7" type="3D" swapxy="true" scaling="uint8">
<table name="Load" address="611b0" type="X Axis" elements="16" scaling="Load"/>
<table name="RPM" address="61194" type="Y Axis" elements="11" scaling="RPM"/>
</table>

55570006:

Code:

<table name="P0300 #1.1" category="Misc" address="567a3" type="3D" swapxy="true" scaling="uint8">
<table name="Load" address="61408" type="X Axis" elements="16" scaling="Load"/>
<table name="RPM" address="613ec" type="Y Axis" elements="11" scaling="RPM"/>
</table>

<table name="P0300 #1.2" category="Misc" address="5685b" type="3D" swapxy="true" scaling="uint8">
<table name="Load" address="61408" type="X Axis" elements="16" scaling="Load"/>
<table name="RPM" address="613ec" type="Y Axis" elements="11" scaling="RPM"/>
</table>

59580004:

Code:

    <table name="P0300 #1.1" category="Misc" address="567bb" type="3D" swapxy="true" scaling="uint8">
        <table name="Load" address="61ace" type="X Axis" elements="16" scaling="Load"/>
        <table name="RPM" address="61ab2" type="Y Axis" elements="11" scaling="RPM"/>
    </table>

    <table name="P0300 #1.2" category="Misc" address="56873" type="3D" swapxy="true" scaling="uint8">
        <table name="Load" address="61ace" type="X Axis" elements="16" scaling="Load"/>
        <table name="RPM" address="61ab2" type="Y Axis" elements="11" scaling="RPM"/>
    </table>

Basically the ECU maintains a average of the RPM, when the RPM increases or decreases too quickly, ie above the map, it will signal that a misfire probably just occured. Hit enough of these events in a certain time period and bam, you will get P0300

Please note that I have noticed that P0300 can be caused by an excessive lean condition, so all efforts should be made to resolve this condition before using the above maps.

Jon@5150 Racing, has been testing these out and apparently the problem is fixed by increasing the numbers in the maps.

Anyways good luck and happy tunering!

	&lt;table name="Load" address="611ec" type="X Axis" elements="16" scaling="Load"/&gt;
	&lt;table name="RPM" address="611d0" type="Y Axis" elements="11" scaling="RPM"/&gt;
&lt;/table&gt;

&lt;table name="P0300 #1.2" category="Misc" address="567bb" type="3D" swapxy="true" scaling="uint8"&gt;
	&lt;table name="Load" address="611ec" type="X Axis" elements="16" scaling="Load"/&gt;
