I need to pick someones brain, please. I am wanting to swap out my K24A4 from my 2005 Honda Accord to a K24A2. Will I have to get a new ECU? I've heard that I will have to and have heard that I will not have to.

Can someone please help?

Thanks,
Ponce

 

Are you aware that there already is a thread on this site about this swap? Check out:

^That thread tells you how to swap a K24A2 into an EP3 swapping it into a 05 accord would be different.

 

Hello all, I'm doing a swap of my 2003 accord from a k24a4 to k24a2. I don't intend to change my ECU, I intend to use the A4's intake manifold, throttle body and exhaust manifold. Would it work with the a2 engine? What would the performance be like? Please help.
