I'm trying to update my 08 evo x GSR to the newest ROM file.

I was able to read my ecu and save it on to my pc as a hex file

The rom info
Internal ID:52680018
Inherits: 52680015

I think the newest is 52680024,

I downloaded the xml file from this site but i can not open it in EcuFlash and i have no idea how to work with it.

What am i not doing right?

Im guessing its because what im downloading from http://goldenevo.com/ is not acutally a rom but the defintion file so ecuflash can read it.

Ok so i loaded the definition into ecu flash,

downloaded the rom

it still wont let me open it.

it says unknown rom.

i tried to change the file extension to hex or bin..

nothing..

im in over my head lol

Make sure you put the XML file into the correct folder. It needs to be in your RomMetaData folder. Double check the folder that EcuFlash is pointing to for its definitions.

ok so i have both the rom and xml file in a directory on my desktop
i point the rom folder and metadata folder to the folder.

Renamed the file to hex and still unknown rom

i cant even open gunzos 93 map
Evo_XGSR-93OctIntExh

it says unknown.

Success,

sort of..

i downloaded all the roms on the site and all the definitions.
all the exisiting hex ones work!

22-24 do not, are they loaded differently?

i also noticed these are all 300kb vs 1mb of the other roms.. so they must only be part of the file.... hmm
 
#9 ·
why on earth are these double compressed with the 1st compressed file's extention taken off?

uncompressed the first file 52680024
uncompressed that with winrar and i got the full 1mb rom from 5260024.hex

:wtfsign:

finally flashed to 52680024!

from 52680018 to 52680024 seems like it made the motor come alive in the top end, it might be a placebo though have to see how it is tomorrow.

thanks for the help!

Gas milage is way better and the motor revs better at the top end.

i got 25mpg today going around town, old flash i used to get 19-20mpg
 
#14 ·
25MPG? I think I'm going to just switch to this one until summer. The only time I ever see 25mpg is if I reset the mpg on the highway and let off the gas for a bit.

You can have a bad definition and still be able to flash a good rom to your car. It's when you want to start changing things on the good rom with a bad definition that you get into trouble. i.e. You change shit you shouldn't be changing.

Then something is wrong with your MAF scalings. I tune cars so that the Actual AFR and Map AFR are close. Not exact, but close. It really helps things run properly.

so... at the risk of opening an old thread - do i just copy and paste the changes i want then from the rom that i download? i dont want to open a new thread just to ask this when i see its kind of being answered in this thread...
im ready to flash, but i want to make sure that im getting the correct values changed and not changing too much - if that makes sense...
