ROM version 96940013
 

Hi Everyone,

It looks like the ROM version on my 2005 Evo 8 is 96940013, EcuFlash says that this is an undefined image but after searching the forums I noticed a post that said that this version can be correctly defined as an 11.

Can anyone confirm this?

Best regards,
B.

Has the car been reflashed by...

*cough* someone?

I had a customer who came to me with this definition. I switched it back to 11... and flashed his car. Or maybe it was 96940014. Not sure, but if it's a USDM car and rom... and it's an 05. It should be a 96940011 rom. My money is on someone doing that in an effort to "hide their hella mad tyte tuning skills" or lack there of.

Save that rom. Switch it and flash the car.

This was actually done by a local Mitsu dealer.

That's actually very interesting, if it's really a legitimate Mitsubishi reflash rather than an aftermarket tune. I'd be very interested in seeing a copy of that ROM, for comparison against 96940011 (what I think most of us consider the last VIII USDM ROM release that Mitsu made); can you read it and post it somewhere? (Rapidshare, etc)

Here is the link to the original ROM that I pulled off of the Evo

Please keep in mind that I am not an expert at this at all, I am working off the basis of EcuFlash v1.42.2595 telling me that this is an unknown image and after using 96940011 as a template the version of this ROM appears to be 96940013

A very quick look suggests that this has quite a few differences from a standard 96940011; from 0x2e500 until the end of the ROM, things are quite different, and it looks like the MUT table is in a different location (edit: to 3f37c, near as I can tell).

I'll take a look with the IDA later to see what the code differences are, but it looks like this might actually be a new version of Mitsubishi's '05 image. Which means, while MOST stuff will probably work from the 96940011 XML, I'd bet there's at least a few things that have moved.

Yeah I noticed the 'odd' MUT table structure when using the 11 XML as a template

ttt, we found a 0013 today also.

might it be a factory fix for throttle hang, or some other idiotism?

It was supposed to be the P0300 as far as I have seen. I associated with the 0011 and it was close enough I just tuned it as is. I think at this point the fact that we can just switch to the 9365, or turn the P0300s off, fix throttle hang, etc. Its odd that its that different though.

I just changed it to an 11 and sent it back to the ecu with the modified rom. Done.

FYI, I just finished going through the EcuFlash 1.42.2595 XML for 96940011 table by table, comparing it to 96940013, and the only real difference is the MUT table location. Change that to 3f37c, and you can treat this ROM as the same thing.

This does not apply to patches; those need to be evaluated on a case-by-case basis, and there's a good possibility that many will need tweaking. But, the vast majority of the tables haven't budged.

I've attached a modified 96940013.xml that you should be able to unzip and save to C:\Program Files\OpenECU\EcuFlash\rommetadata\mitsubishi\evo. This should work with the latest (1.42) release of EcuFlash; older versions will require tweaking, but if you're sticking with an older version (or older XML format), you probably already know what needs to be done anyway. ;) I haven't incorporated any other tables that are missing from the EcuFlash definitions; I'll leave that for someone else to maintain, and some of those very well might have moved around.

Basically, use caution applying anything 96940011-related to 96940013 blindly, without understanding what you're actually tweaking under the hood.

(This is about all the support I'll be willing to provide for this ROM, personally. But it sucks that someone with a recent dealer reflash can't get up and running with basic tuning without jumping into the poorly documented mess that is swapping ROMs; if you're new to tuning, that's not the place I'd suggest starting. So, I figured I'd at least get them to the same place someone starting with 96940011 would be at.)

I know there must be tons of 05' EVO's that have yet to be tuned, but this 0013 seems to be extremely rare. Where did it come from? Why is it that the MUT table is different? Is there more space in the ROM when using 0013?

I have only ever seen it on 05 MR's which might be coincidence but out of 3 that is the one common thread. One admitted to having a dealer reflash done, the others didnt know what I was talking about, so who knows :)

Near as I can tell, it's just a newer release for '05s than the original 96940011; I'd expect anyone who gets a reflash from a dealer will get 0013 from here on out.
