ECU swapping

a friend of mine keeps telling me I should put his 9k aero ecu in my ng900. Am I right when I say you cant do that because of the displacement diference?

There are more things then just the displacement issues. You also have different ways that the car uses sensors and such as well. The speed sensor from a NG is different then how a 9K does it and there are other differences as well.


It is possible but there will probably be too much to do to make it worth while.

with the difference in the speedo sensor i believe you would not only be running lean from the displacement difference, but also would be stuck in base boost.
