I have a 2009 Ralliart that I bought used with 33k miles. Everything on it looks stock except it has a K&N drop in air filter (Stock intake, exhaust, IC, IC piping, BOV). I have my tactrix cable and read from the ECU to save copies of the factory tune, however once it reads from the ECU it says unknown ROM. Does this happen for the factory tune or does this mean the previous owner has uploaded a custom tune?

I have the GST boost pill and new hose assembly so I can just put the pill in the new hose and swap it out, I really want to install this pill and load the 93 oct tune for it, but I don't want to risk damaging anything if it already has a custom tune and possibly an aftermarket part other than what I listed above.

I have not yet pulled the old hose off and pushed out the boost pill to see if it matches the one in the new hose yet; its the middle of winter here and would rather not try to wrestle off that hose in cold weather unless I have to, so I am hoping there is an easier way to tell, and assuming it is the factory pill I would like to know what I can do next.

Any advice or information would greatly be appreciated.

Thanks!

 

It means you do not have the correct definition files loaded up for ECUFLash to read the ROM properly. You should be able to find an appropriate definitions XML file here: http://goldenevo.com/

 

Well have you downloaded the definition file for your car? Go to goldenevo.com if you have not done so. This will allow the tactrix to read the rom for you car rom ID. Once you have that, you can try to find a stock rom for your car, i'm sure there will be one out there. Then you can compare the 2 roms in ecuflash to see if there have been any changes to the rom you pulled from your car. Good luck with all this. http://norcalmotorsports.org/users/b...M_53600010.hexFind your rom here.

 

Okay, does it matter if I download as file or download base as file? And how do I load the XML file for ECU Flash to read the ROM correctly?

 

Just get the xml file, download it, makes it easier. Then when you have it, you have to put it in your ecuflash directory, not sure of correct place, but look till you find mitsubishi, then lancer, stick it in there. When you load up ecuflash, at the top it will say how many files it has loaded, if you put it in right place, then it should increase by one. Also, you have to restart ecuflash for it to find the new xml file.

 

Thank you for your help, I think it worked. I put the XML in the Lancer directory and it no longer said unknown ROM and everything populated except ECU ID and Case ID, is it an issue that the ECU and Case ID didn't populate or is that to be expected?

 

When I loaded the http://norcalmotorsports.org/users/b...M_53600010.hex ROM I noticed you can see ROM info, Timing, Fuel, Intake, Turbo, Limits, and Knock detection..... None of that shows up in the ROM I read from the ECU, why is this?

 

As long as all the major stuff is there, then I think you are fine. I am not sure about ecu id. Does it list your rom ID? Now you can save that rom, load up that other stock one I posted and in ecuflash under File, there is a compare roms button.

 

If you can post some screen shots it might help more. In one post you said it all populated, but then said it showed none of the major stuff, like timing, fuel etc...So I am a little confused.

 

Okay I did a compare, it is attached as ECU Compare.

The image attached named ECU is just a screenshot of the ECU after I read it, as you can see it only has info about the ROM and nothing else, does this mean I need a different definitions file?

If you look in the ECU Compare picture you can see how there is a lot more information than in the second picture, the first picture shows info from the ROM I downloaded from the link you gave me, 2nd picture is ROM thats currently on ECU

 

In the compare there are some NOs, so the ROMs don't match, however I noticed under "year" in the info tab for the ROM I downloaded it says 2008 and the ROM currently on the car says 2009, so I am not even sure if that is the right ROM to compare it to. Also the ROM i downloaded in info says "Inherits: evo10base"

 

I see, you have rom ID 53610013, so you need the xml file for that. I think I posted stock rom for id 53610010. I suggest getting all the xml files for all 2009 ralliarts. Then read your ecu again. Also, when I say compare, I mean the basemaps, and not compare ECU. The compare ROMS is under the FILE heading, assuming you have the latest version of ecuflash. Not sure where you can find a stock rom for your ID. Someone with more knowledge will have to chime in here to say what the differences are between the different rom ids for the 2009 RA.

 

Okay, thanks for all of your help so far, I greatly appreciate it. Will I need the definition XML file for rom ID 53600013? Or just find a stock ROM for 53600013 to compare them to see if my ROM is stock?

when writing to the ECU does it matter what definition files are in the ECU directory?

 

Nope, just need the xml file there. I have downloaded pretty much every xml for every year, so if I every want to compare any basemap or ROM I can. So just get them all, put them in same directory as the other one and you are set. You will have to ask around for the stock rom assuming it is not the same as the previous one I mentioned. But like I said, you want to compare the actual ROMS, when you do this, it will indicate what maps etc... are different, etc, if the timing maps are different, it will indicate this. Then you can find out if you have a different rom. For instance, if it does say your timing map is different, but when you compare them, there are only a few numbers changed, then i'd say you have stock rom. But if the whole table is changed, which would be the case if you compared to say the GST basemap, then your car has probably been tuned. Once you load up a rom, if you click on the little box beside the table, it will pop up. So you can open tables from any rom you have open (you need to have both roms opened to compare them).

 

So I don't need the definition XML file for my internal ID of 53600013 to write the GST basemap to the ECU? I just need it to read from the ECU so I have a copy and to compare that copy to see if its factory?
