Hello,

In 2008, an article about ECUTEK 2008 Evo X SST maps appeared on the "LancerEvo Magazine No.37" magazine. In that article, there was a map named "Map engine load" which defines Engine Load from Manifold Pressure(Bar)(X-Axis) and RPM(Y-Axis). It was one of the scaling maps(e.g. "MAF scaling 1-3" or "MAF compensation#1-#3"), I think.

And, recently　I'm guessing that in some case, maybe changing scaling table(s) needed. so I've been seeking this map by a binary editor and Excel. So far no outcomes...

Anyone knows about anything about the map, could you help me?

 

MAP Mass Air Flow Scaling 1 / 2 / 3?

What ROM ID are you looking at it for?

Thank you for replying Bryan,

I'm seeking "Map engine load"(one of the table ECUTEK named).

It defines Engine Load from Manifold Pressure(Bar)(X-Axis) and RPM(Y-Axis).

It seems like below:


added(sorry forgatton):52360018(JDM, 5MT, latest)

 

Not sure about JDM rom but for USDM 526800215-52680022 its:

<table name="MAP Mass Air Flow Scaling #1" address="60454">
<table name="MAP" address="62a2e"/>
<table name="RPM" address="62a02"/>
</table>

<table name="MAP Mass Air Flow Scaling #2" address="60178">
<table name="MAP" address="62a2e"/>
<table name="RPM" address="62a02"/>
</table>

<table name="MAP Mass Air Flow Scaling #3" address="5fe9c">
<table name="MAP" address="62a2e"/>
<table name="RPM" address="62a02"/>
</table>

at least they got the scaling right

 

Bryan,

Thank you so much, Bryan. I got the MAP MAF scalings! There are 3 maps!
(and Golden, his evo10base_2010.xml helped me, too!)

One quick quiestion about the x and y axes　start addreses.

If the values of axes　were ajusted from to the top of the elements, the RPM starts from 74 to 7500 and MAP starts from 0.06 to 2.40(like jdm below). But reffering to the usdm(52680015), it seems to starting from the second one.

Should I correct the jdm axes starting address like the usdm? What to you think about that?

jdm(52360018):


usdm(52680015):

 

Nice Work
52360018 helpful information from you guys found a table MAP Mass Air Flow.
I added 52360018.xml.

<table name="MAP Mass Air Flow Scaling #1" address="60458" type="3D" level="1" swapxy="true" scaling="uint16">
<table name="X" address="62a32" type="X Axis" elements="19" scaling="MAP16"/>
<table name="Y" address="62a08" type="Y Axis" elements="19" scaling="RPM"/>
</table>

<table name="MAP Mass Air Flow Scaling #2" address="6017c" type="3D" level="1" swapxy="true" scaling="uint16">
<table name="X" address="62a32" type="X Axis" elements="19" scaling="MAP16"/>
<table name="Y" address="62a08" type="Y Axis" elements="19" scaling="RPM"/>
</table>

<table name="MAP Mass Air Flow Scaling #3" address="5fea0" type="3D" level="1" swapxy="true" scaling="uint16">
<table name="X" address="62a32" type="X Axis" elements="19" scaling="MAP16"/>
<table name="Y" address="62a08" type="Y Axis" elements="19" scaling="RPM"/>
</table>


<scaling name="MAPMAF2Load" units="units" toexpr="x*41360/65536/100" frexpr="" format="%.1f" min="0" max="400" inc="1" storagetype="uint16" endian="big"/>
<table name="Load MAP Mass Air Flow Scaling #1" address="60458" type="3D" level="1" swapxy="true" scaling="MAPMAF2Load">
<table name="X" address="62a32" type="X Axis" elements="19" scaling="MAP16"/>
<table name="Y" address="62a08" type="Y Axis" elements="19" scaling="RPM"/>
</table>

<table name="Load MAP Mass Air Flow Scaling #2" address="6017c" type="3D" level="1" swapxy="true" scaling="MAPMAF2Load">
<table name="X" address="62a32" type="X Axis" elements="19" scaling="MAP16"/>
<table name="Y" address="62a08" type="Y Axis" elements="19" scaling="RPM"/>
</table>

<table name="Load MAP Mass Air Flow Scaling #3" address="5fea0" type="3D" level="1" swapxy="true" scaling="MAPMAF2Load">
<table name="X" address="62a32" type="X Axis" elements="19" scaling="MAP16"/>
<table name="Y" address="62a08" type="Y Axis" elements="19" scaling="RPM"/>
</table>

Then, MAP Mass AirFlow you convert a table, Load Value could be calculated.
Roughly, 10-320 so as to consider the value of the Load Value. (Load Calculate Table!?)

Load Value = CELL(MAF) * MAFMax / 65536 / 100
MAFMax(MAFSize?) : 41360 (JDM value, from MAF Compensation #3, 5Volt)

However, MAP Value is different from the ECUTeK.
You have put ECUTeK reference value, this value is published in the magazine.
Boost value, ECUTek who I think is right, invite you?

Thanks

 

That's the scaling for those 3 tables

They convert directly into load...

 

Hi, tephra,

I used scaling(Loadify), too big Load Value,

 

thats about right.

the ECU does some tricky maths to get the actual final load value, but these are as good as for the time being...

 

Is this the table you would adjust when dropping in an omni / orther 4 bar sensor to get AFR to match up to the fuel table with the factory MAP?

I'm guessing there are more, but this could be an easy place to start.... looks kind of like one of the features from dsmlink v2

 

yep - just the axis thou

 

Yes or if you put a different turbo/MAF then stock on a 09-2010 Ralliart.

I just noticed the JDM table only goes to 2.40 bar. Is that correct or is your def incorrect?

- Bryan

 

i would say bad def
