Scaling Omni 4bar MAP for JDM E7.

Hey guys,

Gonna install my newly received Omni 4-bar map sensor later tonight on my car, have reviewed all the scaling mods by 'mrfred' (legend) and all relate to USDM cars.

I'm going to try the 2003 E8 code below and see how that goes, but does anyone before I do it have any exprience throwing them onto an E7?
I'm running 90550001 btw.

Cheers.

--------------------
mrfred's code for USDM '03 E8.

ROM Mods for 2003 USDM Evo 8 ROM 94170008

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 94170008.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 Test 1: Mid VE Max Voltage" category="MAPSensor" address="2048" type="1D" level="1" scaling="Volts16"/>

<table name="MAP Test 1: Mid VE Min Voltage" category="MAPSensor" address="2046" type="1D" level="1" scaling="Volts16"/>

<table name="MAP Test 2: Low VE Max Voltage" category="MAPSensor" address="204C" type="1D" level="1" scaling="Volts16"/>

<table name="MAP Test 3: High VE Min Voltage" category="MAPSensor" address="2050" 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:

MAP Test 1: Mid VE High Voltage Test -- Change from 4.61 volts to 4.90 volts.

MAP Test 1: Mid VE Low Voltage Test -- Change from 0.10 volts to 0.06 volts.

MAP Test 3: High VE Voltage Test -- Change from 1.80 volts to 0.51 volts.

In ECUFlash, find the "Periphery2 (FCA) Bits" table. Change bit.9 from 1 to 0. Use the "minus" key on the keyboard. This disables the P0401 (EGR) test.

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

Nothing bad will happen. You may get a P1400 MAP sensor error or P0401 EGR Test error if these are enabled in the FCA periphery bits 10 and 9 of your 9653XXXX ROM. I turned mine off because I can see if the MAP sensor is working because I use it for a direct boost signal.
