I heard that they have always been protected against the modding by putting the little epoxy over the contacts. This was their revision against people modding it. Im not sure if this is true though.
well, its also mostly because i no u guys are reliable, since u r the one and only forum that helped me pick all my parts, although i am still making revisions
This is the guide form dfi-street. They talk about removing the epoxy from the contacts and people are still doing this up too today. I think that the Ultra-d are still moddable but i wont be 100% sure until i do mine.
