We are pleased to announce a programmable ECU solution for the 00-05 S2000.



Full details are at http://www.hondata.com/s2000kpro.html, but a summary is below:

- RSX ECU modified to suit the S2000 wiring harness.
- same features as the RSX KPro - covering big injectors, boost, nitrous, ITBs, boost control etc
- some mechanical components need to be updated to the 06-07 parts.
- will not work on the 06-07 (due to drive by wire)
- available early May (estimated date only).
- price $1795 plus approximately $300 of Honda parts.

We would request that you do not call us for more information. We will do our best to answer any questions on this forum or our forum, and either update the page on our website or update this post. If there is something you desperately need to know - you've survived 7 years without knowing so far, just be patient.

Questions / Answers

Photos - we'll take some photos next week. It looks just like the RSX KPro, except the S2000 connector sticks out approximately 1.5".

Power gain - ECUs do not make power. Engines do. A badly tuned ECU can reduce power, but the rest is up to the engine. With the S2000 KPro the engine will be able to obtain it's maximum potential output.

Existing ECUs - we only will offset the S2000 KPro with a new ECU from Honda. Existing ECUs, KPro or not, cannot be used.

Base calibrations - We have an AP1 basemap, and should get an AP2 basemap before the release. Basemaps are just a starting point, and people should realize that a good tuner can replicate whatever basemap we might provide in about 10 minutes.

Primary/Secondary o2 sensor - closed loop runs off the primary oxygen sensor. It cannot run off the secondary oxygen sensor because the cat changes the AF ratio. What we have done, on ECUs which don't support a narrow band primary oxygen sensor, is to route the S2000 oxygen sensor via the secondary oxygen circuitry. Internally the ECU treats the secondary as the primary and ignores the secondary.

Widebands - You can route the wideband analog voltage output into the ECU ELD input for datalogging purposes. The PLX wideband is $195 with sensor (no display) and $315 with display. It has both narrow and wideband analog outputs too. I've been told the NGK wideband is good. http://www.ngk.com/afx/ $295 with display and wideband analog output.

Bracket - a mounting bracket which locates the ECU in the stock location using the stock mounting points.

Note that the bracket in this photo is an early prototype - the final product will be laser cut.

 

wow! finally! too bad its not for 06

 

HOLY MOLLLYYYYYYYYYYYYYYYYY!!!!!!!!!!!!!!!!!!!!!!!!!!!! !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! !!!!!!!!!!!!!!!!!!!!!

 

Interesting!

 

Yeah, 06-07 guys I guess would have to go with AEM stand alone.

 

Yes. Good to know but... what would one expect to "gain" from buying your product. In other words, if I want to burn the money for half a supercharger on your product, what can I expect to "run" after installing it compared to a stock S2000?

 

They have one for the '06

http://www.hondata.com/reflash_s2k_06.html

it's priced much more reasonable as well.

You can unlock alot of power in the K series motors but F20c-F22c are well tuned

 

I guessing the engine needs to have all it's mods in place before purchasing this product for maximum benefits to be realized ?

 

That's nice to know.
Definitely a lot cheaper.

 

dam thats expensive... but glad it finally came out
