What if your going with a aftermarket manifold and theres no place for the EGR to be hooked back up ?

Im throwing a p0403 Exhaust Gas Recirculation Malfunction.

Would anyone have any idea what this would mean ?

Ohh nice ty at least i know now im not that much of an ***. I guess ill have to do some serious searching.

I have one other question not petaining to this topic really but would anyone know why i wouldnt be getting any fuel trim readings in mitsulogger along with o2 censor feedback trim.

I was thinking the obvious o2 censor gone bad. If to much gas hits a o2 censor dont they like foul out ? or no ?

check the mitsu xml file to make sure it's enabled which should say, "y" after the word "logged" ..
As far as the diabling the EGR check. Here is the info, be careful with what you disable. (From Aktivematrix.com)

Add this address(universal to all ecu's) to the bottom of your "evo7base" save it. eg

<table name="ECU_PEREPHERY" category="Misc" address="faa" type="1D" level="4" scaling="Hex16"/>
<table name="ECU_PEREPHERY1" category="Misc" address="fba" type="1D" level="4" scaling="Hex16"/>
<table name="ECU_PEREPHERY2" category="Misc" address="fca" type="1D" level="4" scaling="Hex16"/>
<table name="ECU_PEREPHERY3" category="Misc" address="fda" type="1D" level="4" scaling="Hex16"/>



The settings:

If you want to disable EVAP set ECU Perephery2 = 0xCFDF

If you want to disable EGR set ECU Perephery2 = 0xEDDF

If you want to disable EVAP and EGR set ECU Perephery2 = 0xCDDF

The factory default for ECU Perephery2 = 0xEFDF ....just copy and paste.

Ok seems like all went well. I got it all pasted into my rom definition and had no problems opening it up again. I checked my xml file for mitsulogger also and i had all the "y"'s in the right place where u said.

Im not getting any o2 censor readings in anything which i am now assuming is my main problem. I have scan tech and under o2 censor one i am only reading .020 volts and censor 2 im getting 0 volts.

The car only has 23000k miles on it and hasnt been drivin on the road in two years. But after the mods i did i had a very poor map and my injectors were dirty. So the car was running really rich and i ended up fouling a few sets of plugs trying to get it dialed in.

Its still running rich and i was thinking the excess gas ruined the o2 censors. Or is that not possible ?
