Guys I have a tetrix 2.0 cable and im trying to read the rom on an 03 evo using ecuflash. It makes 3 attempts but get no responce. Strange thing is I can log the car fine with evoscan. I know my cable is good as I can read anouther 03 and an 06 fine. What am I missing? Any help I would appreciate. Thanks.

 

You ecu may be locked, has it been tuned before by anyone. Tuners will sometimes change the init code inside your ecu say that the nomal ECUFLASH settings will not allow you to read your rom. The easiest way for you to do it would be to use the ECUFLASH unlocker program. and once you are in change your init code back to 0001

 

Thanks sounds like that is my issew as I think the timing tables have been messed with. Thanks.

 

does anyone know if you need a specific version of ecuflash in order to use the unlocker tool? ive tried it several times on my friends '04 that is locked and it hasn't worked

ecuflash 1.42

 

^^^It should work with v1.42 but make sure you open the unlocker and its running before you open ecuflash.

 

tried that and im still having trouble with it. I am running vista though, maybe XP?

 

I never tried on vista...i would try xp if you can.

 

Did you try running it as administrator?

I have def used it with 1.42

 

Ok I can read and burn now but when I load the stock rom file for an 03 the car wont start. I notice the init code (highlighted in blue) and imob caint be changed either. How can I edit this sucker? Looks like whoever flashed it previously scrambled the hex.

I compressed the flash but its 118k so I caint post it.

Any ideas on what I am missing here? thanks

 

Change your user level to developer or advanced in the file - options that way you can mess with those fields.

If the hex is scrambled just means the internal rom id has been messed with.

Likely the immobilizer is not correct for your car on the stock rom and its dying you can disable it in the periphery bits FAA.

 

Ok so I have a vista (x86) laptop and running the latest ecuflash (1.42) and following the wiki to add the periphery bits in notpad it will not let me save it as vista says the file dosent exsist? Witch is dumb cause how can I add code to the file if it dosent exsist? What am I missing? Thanks

 

Never heard of that problem but I'm using Windows 7 64 bit ultimate so they should be similiar. It may be a permissions deal that's preventing you from saving the file.
