Anyone can help me get the definition on this jdm rom. Thanks!

 

That's a weird ID. Kinda TephraXMod, on top of a suffix that's way past any prior revision numbery thing I've seen to date. I'll take a look at it from the inside.

Perhaps someone's flipped the ROM ID manually after tuning it, to make it "theirs". Or perhaps there's more to JDM factory ROMs than I know, lol.

You may be best served by using a "known" 5236 revision. But we'll see.

I'll go probe its inner secrets...

Rich

 

Yeah, that's got Tephra stuff in it... AltMaps and KnockCEL.

But it doesn't match known 5236 ROM layouts (0016, 0018).

Perhaps Tephra can shed some light on this...

Rich

 

Thanks Rich for looking at it, so someone has changed the ROM id?

 

Can i just flash in a known 08 JDM 5mt rom in? Will the car even start without the immobilizer code?

 

Evo X doesn't have immobiliser code stuff like the older Evos (apparently) did. Before my time.

You can flash one of the well-known 5236 ROMs over it.

But a TephraXMod ROM is a pretty special thing. I suggest you email it to tephra.... tephra {at} gmail <dot> com

Ask what the story is, and if he knows what this is. It's possible he did it, but it's possible someone else familiar with assembler/ECU has "ported" his work.

Rich

 

Thanks Rich, i'll email Tephra and see whether he could give a hand on this.

 

Rich, you need to look closer... :-)

It's a 5304 base rom. So I'm guessing it is from TephraXMOD-53040110.

That makes it an EDM based rom.

 

I guess I did! All I did was upload it to your site's "ROM check" thing, lol.

Rich

 

Maybe I should make the rom check thing a little smarter. It could, in theory, identify this type of rom id change.

 

Here's one way to proceed - use the attached XML. This points the wacky, manually edited ROM ID at 53040010.

Bear in mind that there are a few oddities still...

- The "TephraXMOD" alternate maps don't seem to be fully set up. Injector scaling, fuel and timing maps aren't present in the AltMap set. Perhaps it has been coded differently as a "port" by someone else.

- Boost limit and boost limit timer have been pseudo-disabled, ie. set to 319 and 6000ms respectively. Not the ideal approach - I've got a patch that does this better, lol.

- Boost targets seem to still be load-based and quite low. Possibly unused... given the other changes.


Anyway, with this XML, you should be able to compare the car's current tune to factory 53040010 in EcuFlash "File / Compare ROMs".

I expect you'll probably decide to start with a known, sensible ROM instead of this one... even though (or because of) it's quite an interesting animal, lol.


[edit]You'll also need the TephraXMod "53040110" XML installed, and the regular 53040010 XML installed - from Golden's site.


Good luck,

Rich
