2005 EVO MR

After installing the map sensor my car doesnt run right. It would not boost past .5 bar and eventually threw a P0505 code for the irregular idle. Sometimes the car would not start. I replaced the 4 bar with the stock sensor and adjusted the settings to stock and now the car runs normally.

I made these compatibility changes from a previous thread. Is there something else I need to do? I checked several times to make sure I inputed everything correctly. Thank you in advance.


ROM Mods for 2005 USDM Evo 8 ROM 96940011

First is to add some definitions to your ECUFlash ROM XML definition file found in:

C:\Program Files\OpenECU\EcuFlash\rommetadata\mitsubishi\evo

Open the 96940011.xml file with the text/XML editor of your choice. Scroll down to the bottom of the file. Add the following lines just before the </rom> tag (copy everything *between* the ----):

----
<table name="MAP Scaling" category="MAPSensor" address="57D2" type="2D" level="1" scaling="uint8">
<table name="MAP Output" address="6ED4" type="Y Axis" elements="9" scaling="Volts16"/>
</table>

<table name="MAP Fault Trig: Mid VE Max #1" category="MAPSensor" address="28B4" type="1D" level="1" scaling="Volts16"/>

<table name="MAP Fault Trig: Mid VE Min #1" category="MAPSensor" address="2894" type="1D" level="1" scaling="Volts16"/>

<table name="MAP Fault Trig High VE #1" category="MAPSensor" address="289A" type="1D" level="1" scaling="Volts16"/>

<table name="MAP vs MAF Baro" category="MAPSensor" address="2802" type="1D" level="1" scaling="uint16"/>

<table name="MAP Comparison" category="MAPSensor" address="27FE" type="1D" level="1" scaling="Volts16"/>
----

After modifying and saving the ROM xml file, launch ECUFlash, open your ROM, and find the new entries. Note that they have their own category. It may be necessary to set ECUFlash to "Developer" mode in the ECUFlash options (and relaunch ECUFlash) to be able to see the tables. Here is what needs to be changed in ECUFlash:

0.84 11
1.37 20
1.89 31
2.42 40
2.95 48
3.48 57
4.00 67
4.53 80
4.98 255

Change the values to:

0.51 25
0.90 49
1.29 70
1.68 96
2.07 120
2.46 144
2.85 170
3.24 195
3.63 255

Change the "MAP Fault Trig: Mid VE Max #1" value from 4.80 to 4.90.

Change the "MAP Fault Trig: Mid VE Min #1" value from 0.20 to 0.10.

Change the "MAP Fault Trig High VE #1" value from 1.80 to 0.51.

Change the "MAP vs Baro" parameter from 162 to 77.

Change the "MAP Comparison" value from 4.00 to 1.23.

In ECUFlash, find the "Periphery4 (FEA) Bits" table. Change bit.14 from 1 to 0. This can be done by using the "minus" key on your computer. This disables the P0069 test.

Now find the "Periphery2 (FCA) Bits" table. Change bit.9 from 1 to 0. Use the "minus" key. This disables the PO401 (EGR) test.

Save the ROM file, and flash your ECU with it. That's it for the Evo 9 ROM mods. Now skip down to the end of this post to see instructions for setting up EvoScan/Mitsulogger to log boost.
