I did a search for 96530006 and saw threads about it and it seems like everyone discussing in those threads were 2005 owners. I guess I'll wait until Appauld tests the 96530006.

If that doesn't work, what do you suggest? Would I be able to buy a 2005 ECU and have it run my 2003?

 

Applaudd: 96530006 stock ROM, or you can just use Tephra's 5.10 release.

Note to folks trying this kind of ROM-swapping: be sure to test with your immobilizer disabled, or at least follow the directions on the wiki page for more properly converting your immobilizer (but if you have problems, just disable the immobilizer periphery bit).

 

roger: yes, almost all of us using 96530006 are 2005 USDM owners, because our original ROM (96940011) doesn't have any free space for tephra's additions.

 

The encouragement to try the 2005 ROM on the 2003 comes from the way the 2005 JDM ROM works on the 2003.

I wouldn't be surprised if it was just a few changes needed to get any ECU to run any market/year, except 8 wouldn't run MIVEC, but still run the engine otherwise. Just would need a special effort to break down the differences.

 

I suspect you're very right; Mitsubishi appears to have been very good about not mixing up IRQs and other interrupt vectors across model years, which would have shot this down almost immediately.

In a perfect world, we'd have a fully disassembled, well-commented source code that could be conditionally assembled for the hardware you have and functionality you want. That's what originally prompted me to try and get from a ROM image to a fully assemble-able source.

(Which works, after a fashion, although I still need to find a good solution for automatically replacing large 0xFF blocks with .origin statements, so that rearranging the source becomes a bit easier. But at the end of the day, source code written by a computer (IDA) will always be a bit jarring for a human to use. )

 

I downloaded the 96530006 Testing will begin shortly.

I prefer to use the Tephra version since I love the knock CEL.

More to follow.....

 

Upon initial inspection I found several addresses are different and I found several scalings that are different, and some missing addresses. It will take some time to decypher duplicates in my Evo7Base and the one I downloaded.

As far as the tables go...most of them are perfect matches. I will change the Immobilizer and ECU internal IDs to match my 94170015 and test the ROM once I get the XMLs scaled and addressed.

 

Only immediate issue is that the 96530006 ROM works on the 05 which has ACD and the 03/04 do not. If we could disable that with a patch then I think you will have a reall shot.

 

Does anyone know what the ACD line actually does anything to the ECU and whether it will be missed? Worth trying.

 

I thought the ACD has a seperate ECU all together? Doesn't the Main ECU just receive input from the ACD on what the acd setting is?

 

Yes, but you can run an Evo 7 ECU which expects an ACD input on cars that don't have ACD with no problems.

 

I guess the best way to test it is to run the ROM on a non-acd car. Sounds like it may work.

 

I've put an alpha test of 96260009 on MLR, with a move of Tephra's DEAD variable from 841c to a800. If this location is one that is changed during flashing, but not otherwise, then it should provoke a fresh ROM to RAM copy after a flash like the IX does.

If this works I'll do 9055 and 9653. I'm getting very little feedback of 8859 six months after I posted the original ROM

 

I will be testing on Monday
