You're right. I didn't actually check that one. I just assumed it would the same as all the later US variants. I'll fix up my original post in a few minutes.

Does this code change also apply in the OBD Inspection thread? https://www.evolutionm.net/forums/ec...-mrfred-8.html?

probobly a dumb question,
but since moving to the V7 rom w/ the EGR bits disabled, (decided to see if the car liked it) is there any issues w/ disbling the EGR w/ out a block off late, and leaving the solenoids? The reason to get rid of the solenoids, is to save weight, right? I started reading up on this last night, but didnt come across this question/answer. I probobly need to re-read both threads...
The car seems fine. Havent done any pulls yet...
TIA

i have a question: i have the EGR disabled.. but everything is still hooked up/plugged in. if i have it disabled, do i NEED to remove the solenoid and add the block off plate?

Additionally, removing the solenoids and other parts reduces the clutter and chances of a vac line blowing off.
The last option is to leave it all there and do the "tin can mod" (aka slice your fingers off mod) and just make an EGR gasket that does not have openings on it. Really though, the blockoff plates are only ~$5.
just purchased and in process of setting an appt to have a bunch of stuff done, including removal of all of the solenoids...

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 have two cars here, EDM Evo9's using the stock ROM 88840016, and they both have Magnus intakes on.
"USDM Evo 9 88590013-15 use:
<table name="EGR System Enable/Disable" category="Emissions EGR" address="1041" type="1D" level="2" scaling="uint8"/"
<table name="EGR System Enable/Disable" category="Emissions EGR" address="1041" type="1D" level="2" scaling="uint8"/"
Can you please confirm that the "1041" address is correct for the 88840016 ROM.
Thx.
