Hey everyone RacerGirls Boyfriend. Should have made my own name, but anyways. Need a 2001-2003 ECU if someone can help me with where to get one. Are they all the same and are they all interchangable? Need to know if it will plug and play. WANT THAT EXPANDED REV LIMITER. Thanks everyone

If anyone is looking for power that manifold and throttle body combination I got from Dh was amazing. This Z06 Came off the line and from 20 up I pulled away from him, couldn't believe it.

tru

you will also need the keys, due the transponder on the s2k or you could look for a mugen ecu which has no transponder. which would make it very easy to steal.

From reading some of your other posts I think you have an '04. You're not going to be able to just plug the ecu in from '00 to '03 and get your extra 1k rpms. The engine's internals are different from '03 to '04. Honda did this to get a little extra torque out of the motor, but in the process they had to lower the redline to make the engine safe. As I understand it, the new geometry in the '04 engine at 9krpms is likely to cause damage.

You should really do more research and learning about the S2000 before posting lots of stuff like this. I'm not trying to be an a$$ or anything, I swear. But you did not pull away from a Z06. Even supercharged S2000's with 300rwhp can't compete with a Z06.

There are lots of people that have done way more extensive mods to the head, intake manifold, complete valve train, etc., etc, etc. And the known fact about this car is that there isn't much power to be made with port and polish jobs. And to even take advantage of the power that you can get from head and intake manifold work, you will need an AEM EMS, E-manage, ar at very least, a VAFC to alter the air/fuel ratios since the motor is getting more air. There is also very minimal power gains with a CAI, header, and catback exhaust. Each of these will only add aobut 5hp each. Some headers add 10hp in certain areas of the rpm range though. (but 10hp is barely noticable on the butt dyno)

As for your question about swaping ECU's, you can't do it. The main reason is because the fuel and ignition timing between the two motors is most likely drastically different. One is a 2.2L motor with 8000rpm redline. The other is a 2.0L motor with a 9000rpm redline. The fuel and timing is optimized for the amount of air that the motor is taking in for each car. The piston speeds are also an issue with the 2.2L, but I do think that 9000rpm is still ok on the 2.2L as long as you also modify your valve train to lighter titanium components and stiffer valve springs so the pistons won't hit the valves because of high rpm valve float.



With all that being said, congrats on your new car. I'm sure you will fall in love with it as much as the rest of us have. And there is TONS of great information on this site that you will most likely learn over the coming months.
