Nope not going to work.
MD312467 is from the N23W RVR 5M/T with the 7-bolt 4G63, 510cc injectors, big16g turbo, separate cam/crank triggers and no Cyclone inlet manifold actuation. It is more similar to the Lancer Evo1-3 ECU
MD128618 is from the pre-facelift JDM E38A/E39A VR-4 with 6-bolt 4G63, Cyclone actuation, 450cc injectors and 14b turbo.
Not only are the pin-outs incorrect, but the fuel maps will be different and you wont be able to control the Cyclone inlet manifold.
