^ I have my sensors off my car in a box, you have not disabled them properly, they do not need to be plugged in to anything. I just put electrical tape over the connectors and done.

I will try again once the car is ready to start again. I will try and completely re do the rom and see what happens. Is there a difference between 8 and 9?

this thread has a ton of great info in it. Thanks everyone.

1 question: I shut off the FCA, FEA and FAA bits that were mentioned and I flashed it into the car. No CELs or anything. But I didn't disconnect anything (EGR,EVAP,FPR). I just wanted to make sure the ecu stuff worked.

When I started the car up, cold engine, it idled like it had a carb and big cams around 1000 or below haha. Once it got up to temp it idled fine. I'm assuming this is because I shut everything off and still had it all hooked up.

anyone else have this?

you might want to adjust your idle on cold startup, mine idle kinda agressive the first day then went back to normal.

thanks for the help Evoryder, is the idle on cold start up the tables found here?

yeah that would be it. This site is a library of knowledge. Read up

ok, after some more disassem of the EGR routines, I have found that Periphery 0 (FAA) bit11 does not actually shut off the EGR system until the coolant temp passes ~68C. 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 keep kicking myself in the *** for not doing this when I had my head off a few months back. The pics make it much, MUCH easier to do when you can't see everything that's involved.

This also works on the EDM 96530006.

I thought about including the 96530006, but I didn't think EDM Evos have an EGR system (the EGR hardware). Can anyone confirm?

I don't think it does either, but am not sure & just threw that out there.

Edit: It does show as enabled on this ROM.

I took a look at an EDM Evo 8 FSM, and there is an EGR hardware system, so setting that 1D table to zer for the 96530006 will disable EGR function on USDM cars. I'll modify my post above.
