firstly the motors are gen 2 1989 - 1993
and they only fit these because the pin out on the ecus are different in these models, u will find that the power FC fit ojnly gen 3. If i were you i would just go and get the stand alone ECU ie EMS, Haltek, Altronic, Motec the list goes on and and on, also the benifit is that there is more functionality in these ECUs and more to choose from better performance for your money if u ask me.
good luck
