Ive put an Evo 7 ecu in to a Evo 4 . Been a while since ive worked on an Evo as well I dont have a definition for the Evo either do i need it to turn the Immobilizer off? I downloaded the rom from the ecu and it was save as a srf file. Its a Jdm ecu. When i go into Periphery to the bits table where (FAA) is the immobilizer is already at 0 for disabled. Is there any other piece of information i need or do i need to do anything else
