converting 99860002
Hey all,
I had a local ask me to help him with 99860002. He bought an imported evo 7. He lives in MA and needs to pass emissions. I know nothing about JDM or evo 7 roms.
Questions:
Any help would be much appreciated.
I had a local ask me to help him with 99860002. He bought an imported evo 7. He lives in MA and needs to pass emissions. I know nothing about JDM or evo 7 roms.
Questions:
- Can i convert to an evo 8 ecu or rom? He is willing to buy the 8 ecu if needed. I also need to do the readiness patch so being able to run an 8 rom is necessary.
- Is there a specific evo 7 rom that has any sort of support? Looking for rear o2 removal.
- Is the front o2 sensor heated? Had a problem with not having a heated front o2 on an evo 6 motor.
Any help would be much appreciated.

has it failed an emissions test? the evo 7 does not have a rear 02 sensor AFAIK.the front 02 is heated.there are a few roms for the 7 available i doubt switching to an 8 ecu will help your cause.
I can't speak to running an VIII ROM on that car, although there's definitely no architectural reason it shouldn't work (procs are the same, and interrupts look right to me). I'd give it a try if you have some leeway to do it with your customer; conversion should be the same as converting anyone else to 96530006, just copy the immobilizer and the additional hex value (we really need a better name for that; the traditional "immobilizer" is key-specific, while the other value is ROM-specific).
I have no clue about the front O2 heater, I'm afraid.
Looking through the code for that ROM, there doesn't appear to be any code for the heater test for the rear O2 (which suggests that there's no support for it at all), so I'm guessing the problem you're having with emissions is that the rear O2 tests are "not available", rather than "not ready"?
If so, I think this is the patch you want (referencing acamus' and mrfred's excellent work):
Non-Continuous Monitor Completion Patch
@2F66C DA51 -> EAFF
@2F66E 6AA1 -> 6AA7
Non-Continuous Monitor Availability Patch Part 1
from 4019 to E000
Non-Continuous Monitor Availability Patch Part 2
from 6AA1 to EAFF
Obviously that's totally untested, but might at least get you going. acamus, if you're reading this, can you confirm that the above looks right for that ROM? (This is my first time reading through some of this code. I need to get IDA loaded on my Windows laptop; I really miss the graphing in the Linux console version.)

If this is the car I am thinking it is, I am very familiar with it.
When that car first came to MA it was stock and for a couple years had no problem passing the readiness checks. I believe somewhere along the line, it has been corrupted.
The car had no emissions and no rear o2 IIRC. The front sensor should be heated just like the 8 and 9.
I would honestly start with ringing out all the o2 sensor wires and make sure none of them have been switched at the ECU. For a while the car had a motec in it and there was some assetry going on with the tuner and I wouldn't be surprised if it has been hacked up some.
Keep in mind for an evo 8 ecu to work, you will have to spoof every emissions sensor including the EGR, MDP, and it also has a factory antilag in it.

It seems to be correct.

Well, a lot of the hackery with the ECU was with the previous tuner on the motec.
I have no idea what is going on with it now though. But in order to switch to an 8 ecu, there are a couple pins that need to be switched. I think it is 8 and 22, but double check. It is the fuel pump and a/c circuit.
