i bought my wrx with the xpt tune and need to know how to un install the tune because im getting the ap v3 soon and get a real tune i know i need the trax cable and use my lap top just need to know exactly what to do thanks for any info

 

I don't know much about about xpt or open source etc but I'm pretty sure that when you get your Cobb Ap you can just bring it to your tuner and have them set it all up.

 

You can flash the Accessport right over an xpt map

 

really so I just hook up the cobb ap and reset to factory settings and then load the cobb tunes in till I get a good pro tune

 

Correct

 

ok cool thanks again for the help
