need some help with a swap i have been in the process of getting together. ok i have a 95 cx with the original d15b8 in it and i have a d16y7 thats going in, and i was wondering do i have to do anything to the ecu such as change it out, the ecu i currently have is a p05. i also have a d15b ecu, its at a friends house or would say the code. anything would help out. thanks
