not to be a stick in mud.. but since the 05 and 06 type-s ecu's cant be kproed. they have been pretty much rendered useless, unless going back to stock.. and even the 02-04 type-s ecus, which can be kproed dont go for that much..

you can try to sell it on clubrsx, there tends to be people there that may need it for going back to stock. might be worth a shot..

but otherwise. good luck selling it
