step 4: open ecuflash
step 5: read your ecu's stock map and save it to a SD card,flash drive, or to your pc
step 6: open your desired map
step 7: test write to ecu to make sure of connectivity or errors

the programs are free(ecuflash,enginuity) you will have to go to www.osecuroms.org and register to find the maps for your car some are free and the xpt maps are not and no i have heard of people flashing their cars hundreds of times before

awesome write up.

i think it would be good to post comparisons of stage 1 and stage 2 using enginuity even through stage 4. just so newbees could see the differences. even i want to see the difference between stage1 and stage 4.

Nice write up! Excellent directions and pics.

I've noticed some folks say it may take a few extra cranks to get your WRX started after flashing a new map but that was not the case for me. It started up normally. However, when I first got the Tactrix cable I saved my stock ROM to disk (no writing to the ECU) and it did take a few extra seconds for it to start up after that.

Okay, I CAN use some help with this flash. I have the stage 3 race map. ( I have also flashed stage 2 and stage 3 successfully in the recent past) I saved my xml file to the C:programFiles..... and when I open ecuflash, it has not registered that that file exists. I have restarted my computer, tried to open file before and after reading my ecu, stood on my head and on one foot. Help me out someone. Has anyone had this problem?

Thanks,
Dean

What do you mean it hasn't registered that the file exhists?Are you getting an "error:" or you just can't find the file?
No error. Okay, so you buy the map, download it from the site to your computer, it asks you where to put it, you save it, then save the xml file to the C:\Program Files\OpenECU\EcuFlash\rommetadata\subaru\wrx, then go out to your car, hook everything up (tactrix, green connector (my06) and open ecuflash. When you open ecuflash, then read your ecu, then go to "Open ROM" , there is no ROM to open. So I go and try to manually open it and still , nada. I have had a similar problem every time I buy a map, but after all is said and done , it turns out okay and I really have no idea what has just happened (magic?)
So ,I ended up getting it to work last night around 11:30. I ended up uninstalling ecuflash, sending the zip file over to my other computer and deleting it from my laptop. I then downloaded ecuflash and resent the zip to my laptop, and instead of immediately saving it, I just opened it and extracted the entire zip to my documents and settings folder and then from there was able to save the xml to the program files folder. Flashed the ecu and BAM

BTW, my car is now very fast:D
