Hi,
I searched a bit and found a post with some piece of code for ecuflash :

GSR (I don't have the MR one, but I'm sure it's here somewhere)

Evo10base.xml
Code:

<scaling name="MAFVoltScaling" units="units" toexpr="x*5/1024" frexpr="x*1024/5" format="%.3f" min="0" max="5" inc="1" storagetype="uint16" endian="big"/>

<table name="MAF Compensation" category="Fuel" type="2D" scaling="AirFlow16">
<table name="X" type="X Axis" elements="40" scaling="MAFVoltScaling"/>
</table>

<table name="MAF Compensation #2" category="Fuel" type="2D" level="1" scaling="AirFlow16">
<table name="X" type="X Axis" elements="40" scaling="MAFVoltScaling"/>
</table>

<table name="MAF Compensation #3" category="Fuel" type="2D" level="1" scaling="AirFlow16">
<table name="X" type="X Axis" elements="50" scaling="MAFVoltScaling"/>
</table>

52680015.xml

Code:

<table name="MAF Compensation" address="5753a">
<table name="X" address="615ea"/>
</table>

<table name="MAF Compensation #2" address="5758a">
<table name="X" address="6163a"/>
</table>

<table name="MAF Compensation #3" address="575da">
<table name="X" address="6168a"/>
</table>



The thing is, I would like to check if this piece of code would work on a MR ?
ROM number : 52690019
I don't want to brick the ecu :P
Since I found this post : http://www.evoxforums.com/forums/showthread.php?t=13801&page=2

I hope it could solve the P0171 CEL :-)
