I recently purchased an 02 wrx that needed some fine tuning. It came with a tactrix, so I emailed a tuner with good reviews got the initial Rom but cannot load it. The error code every time is kernal get version. So far I have tried two diff cables, two diff USB cords, two diff laptops, one with windows 7 and one with xp. I am out of ideas. I have to get these injectors scaled or I will not pass emissions. Would them to get a reading from my obd2 port count that out as a possible problem?
