they use a cr27256a i belive , but your gonna need a daughter board to use it , because you cant put the eprom socket right into the kade ecu i dont remember exactly why but you cant, and from what i have heard they dont work to well , if you are on a budget i would suggest staying with the greddy emanage or get a real standalone (aem ems)… learning to program chips is easy and cheap when u have a honda, but not so much on nissan
with the eprom your gonna need much more than a chip burner
