NEW to open ecu, got probs

[BAS]

Hi everyone, I am new to open ecu and am trying to work my way through my first car. I managed to retrieve the file using 2003, but the car is 2005. It is ADM 2005 WRP (sti computer) can anyone point me in the right direction??

the internal ID is A4TH100L but I have to use A4TH100O,

Also can someone tel me why if you hold load for a while it pulls boost out?

thanks
