After a couple of miles, P0403 (EGR Flow Circuit Malfunction) showed up so I disabled it,
but it came back again. Did I miss something?

Ah right the OBDII test set FCA periphery bit 9 to 0 it should be labled with EGR test or something.

I just doubled checked it, its already set to 0




While searching the forums I found this:

Its ok to use if you plan on ripping out all the EGR stuff. However, it turns out that there is a byte length value that completely disables the EGR system and is a better choice to use.

For USDM Evo 8 94170008-15 and EDM Evo 8 96530006 use:

<table name="EGR System Enable/Disable" category="Emissions EGR" address="103D" type="1D" level="2" scaling="uint8"/>

For USDM Evo 8 96420007-11, 96940011, and USDM Evo 9 88590013-15 use:

<table name="EGR System Enable/Disable" category="Emissions EGR" address="1041" type="1D" level="2" scaling="uint8"/>

A value of "0" disables the EGR system and sets the EGR duty to 0% all the time. "1" enables the EGR system.

Oct 4, 2009 - Fixed to show that the EDM Evo 8 96530006 address is 103D instead of 1041.

I already gave you that address hmm..

I defined the egr tests right?

There should be one with a pressure difference volts for the map sensor. Set the pressure diff volts to 0 and I think it will go away.

Gotcha. Should I also set the EGR Map Check to 0?

I have no idea what the map check does really so I would ignore that table for now. Use the pressure difference table for now and I can look at the others at a later time.

Hmm lets set those to the infinite of bad see if it helps.

Set the tests 2 and 3 to 5 volts
Set tests 1 and 4 to 0.1 volts.

IMPORTANT!

Do NOT try the jitter fixes I forgot to remove them from the xml :/ I'll correct them later and send a new xml but tonight I tired

Test Rom for SD
http://www.megaupload.com/?d=3LJ0R3RB

Requires my last xml which is in this thread somewhere I can link to it if needed ^^

Still looking at the 403 code

Edit:
Actually I'm gonna stop looking at it.

4g64 did you try the force ODBII inspection patch?
