Why would you want to do this? You can't do it in the traditional sense. What you can do is use a transponder box that has the immo key inside. These boxes are normally made to allow for remote start on cars with these codes.

If you add the def for the Ecu periphery "faa"

Change the value from the stock value of 0x56Da to 0x56D2. If I was at home I could post the definition but I am sure its around here somewhere. If you have 0x56D8 in there as a value thats for turning off the rear O2 as well. You would want to change the value to 0x56D0.

remember you have to add the 0x though it wont show up.

Wow, I'd prefer to disable to immo as which means I won't have wire the transponder box to get remote start to work! The code is listed in the evo9base XML:

<table name="Immobilizer" category="Misc" address="3ffce" type="1D" level="3" scaling="Hex16"/>

Not sure where to go from here though.

<table name="(periphery 0)" category="Misc" address="faa" type="1D" level="1" scaling="Hex16"/>

Then change the value as I listed above. This works for any Evo that has the immobiliser enabled.

thanks a lot m8s!!!
Today i'll test on one of our cars and i'll let you know the result.

Did you lock yourself out of your ECU by flashing a ROM without the correct Immo code?

Will this work on USDM ROM's too? I am using 96940011

No. I only got a 8 with a Motronic Ecu and i have to set it back with a std Ecu.

Change the value from the stock value of 0x56D8 or 0x56Da to 0x5690. If I was at home I could post the definition but I am sure its around here somewhere.

I'm pretty sure that 0x5690 will also disable your rear O2. I think you want 56D2.

5690 in bin is 101011010010000
56D2 in bin is 101011011010010

Stock should be 56DA
56DA in bin is 101011011011010 (notice that both bits are enabled)

The second bit from the right is the rear O2 enable/disable. The fourth bit from the right is the immobilizer enable/disable.

Good call Eric..I was just going from memory on that one, I knew it was the immobiliser but I couldnt remember if it included an O2 or not.. Being EDM it probably doesnt have the second O2...again from memory.

JohnBradley · Mar 20, 2008, 06:33 PM

56D0 -No rear O2 no Immobilizer
5650-no rear O2, No immobilizer, No knock
5658-no rear O2, No knock sensor
56D8-no rear O2
5698, no front or rear 02
5690, no front 02, rear 02, or immobilizer
56D2, No immobilizer

went and looked at the list I worked up..here are the normal combos.

That's a good point. Basically, whatever the periphery code is, just translate it into binary and then make the fourth bit from the right a 0, then translate back to hex. That's what you will need to flash into your ECU.
