JDM_Wrx

Hi,
i have got my hands on a w6 ecu unit for a my93 wrx which has been upgraded by car station marche. does anyone know anything about these tuners or there units. i'm aware they are japanese. would like to know what they are capable of. i've taken the lid off of the ecu and it looks like a work of art. can supply pictures but have no way of hosting them so will have to be by email.

any help on this unit would be gratefully received.

thanks
Rob
