Anyway it is now fixed and ready to go back in my car. Once I put the ECU back in should I run the car stock for awhile before I flash to Stg 2? My only mods are a turboback that I recently had installed. MY car is an 02 WRX and I just don't want to cause any more problems. So my question is can I flash it right away or should I run it stock for a couple days before I flash it? I just don't want to mess anything up again so I want to be safe, any input would be greatly appreciated. Thanks,
Waiting to flash isn't going to make the process more or less reliable. You should reflash to the stage 2 mapping right away as you should not be running the stock mapping when you are at stage 2 as far as mods. That is assuming you fixed the original issue (bad car battery). If you have not fixed that issue, then I would not reflash until you have (drive very conservatively until then).
