Hi guys I'm pretty sure this part applies to me: As for the unlocking process, CAPA can unlock the box but retain tunes in the box if you so wish. The box I have has what is apparently a very good custom 12psi map in it (you need to make sure it's for the same car, ie. auto, manual, whatever). I rang the Edit tuner who supplied that custom tune to make sure he was happy for me to keep his tune and, to his credit, he was. So CAPA can apparently unlock the box for me, keep that custom 12psi map in the box, but reflash the other two programs with their latest 8psi and 10psi maps I Bought a second hand flash tuner from ebay: It has a custom tune etc, but will it work on my car?? same model, transmission etc. I rang up one place and they said no, he rang up CAPA and they said yes? so if anyone could shed some light on this it would be greatful.
