I have a spare 91 civic hatchback ecu should i swap it into my 90 CRX hf? Are there risks to the engine? Would it improve performance? Would it degrade reliablility?
 
Im glad i got your advice when i did. The person i got the dx from said that the ecu would just give me better feul mapping, and diddnt take that into consideration.
Thank you.
