Since the ecu is made for a different car you also need to change, cam and crank sensors with including trigger wheels, IAT sensor and also the valve cover.
So it gets very expensive and also lots of work, you do get a OBD compliant car though which you cant get with AEM, Haltech or other aftermarket solutions.
There's also the Doctronic ECU option which uses an 'active' adapter harness that converts the signals from your stock cam/crank angle sensors to something that's compatible. No sensors need to be changed. This is the least hassle way to tune a non-DBW ECU. Retains OBD2.

There's also a Megaquirt option that has optional OBD2 compatibility if you want to go full standalone.

4 years ago when I bought my DBW S2000, these weren't available so I just ignored those cars for sale. Now, it seems like a 2004-2005 AP2 is the best S2000 to get. Because they are just as good as the DBW AP2, but have a return-style fuel system for future upgradeability.
