hey, i was wondering if the aem works like the vafc when it comes to the engagement of vtec. as in, making it at 4,8k's for example? does the aem have the option to work with?

dude...what are you trying to say? are you saying can you lower/adjust vtec? if so...yes, its a standalone...

 

why would u want to put your vtec at 4?

cUz vTaK pwNs j00!

 

the lower the vtec...the better, c'mon guys...its the greatest power adder in the world...better than NOSSSSS and turbochargers.

LOL! it's vtech! not vtak!

Actually, i don't think lowering the vtec would hurt. I'm sure you guys have seen stock s2000 dyno sheets and can confirm that there is a pretty large spike when vtec engages. These spikes are bad and my assumption as to why honda left it like that is so that the car "feels" faster. A smooth power band with no "spikes" is ideal and will make more power (mostly midrange) but it won't feel as fast since there are no spikes and feels like a more gradual pull.

To keep this on topic, the AEM EMS, if thats what you're talking, can do everything the VAFC and more. The AEM EMS is a full standalone engine management system while the VAFC is just a piggyback (tricks the stock ecu). With the EMS, you can tune your fuel and ignition timing maps as well to maximize power at any particular rpm. If you're stock, i'd wait until you get some mods to tune your car so you don't waste money if you add parts later on.

 

you can lower vTaK to 500rpms if you want with the EMS.

Sure, lowering the vtec can be a good thing, but if the rest of the engine isn't mod'd or prepared for it, you can lose that area under the curve.

 

0o0o 500rpms vTaK = vTaK g00dness even in reverse!

I always thought that there was still a LITTLE power to unleash even with a fully stock motor? I remember you saying that there could be a slight gain since the stock ECU is such a huge bottle neck for the S2000?

stock ecu seems to be the bottle neck. But for the whole package to work on an NA setup, corners can't be cut, which means you need the cooling package, bolt ons and doesn't hurt running higher octane fuel. There are gains to lowering vtec on this car, but not more than a few hundred rpms. Once you have a proper intake, you can lower vtec much more to take advantage of humps on the dyno chart to help the vtec transition. It's a big cam profile change and takes a few rpms for the motor to recovering from the transition.

 

from what ive read lowering it more than 5700 on the tach loses power. but i guess it depends on what mods you have etc, like vapor said..

 

well every car is different. when Church tuned my VAFC, he tried it at 5600 and then at 5700. the car just didnt like it. it made more power with the stock engagement point. so that is where it currently resides

 

what rpm does vtec engage at in the s2k?

 

I have my vtec set to engage at 4400 disengage at 4200. It works well with an sc. From looking at my dynos...if you used an aem instead of a stock ecu, you will experience a hp loss compared to a stock set up at 4400 but when you pass the previous engagement point youI have more.My difference is about 8hp more. at 5800. I don't know what the gain would be with a stock setup.

ps remember your stock s2k tach reads 200rpm low. wonder if it does that on the 04's too? Anybody know?

AEM on an S2k is great. Prolly best of all is playing with the 2step!

 

anybody have the new aem ems 1052??? if so i know it has the internal uego sensor, smaller unit, and other lil stuff...is this version that much better than the old one??

 

I have the 30-1012 ecu with external WBO2. I tried getting the 30-1052U first. I ordered it and waited a few weeks. It turns out that it will be at least another month until AEM releases it even though Vivid and Horsepowerfreaks both list it on their sites. I'd bet that it will be sometime between Nov 1 and the start of the year when it comes out. I'd highly recommend the VTECFROG extension if you get the 1012. It doesn't even come close to fitting in the kickpanel with the serial cable attached. It may be close enough for some, but I want something very clean with no cutting or compromises. My timing was 2 degrees off(ECU to real). I used a $35 NAPA timing light. The V1.11 program is MUCH smoother than the V0.93 on mine. I literally can't tell the difference between the AEM and stock ECU except for the temp gauge and a little more cranking time- and that's with ZERO tuning or mods to the stock AEM programming. I LOVE IT! I'll start serious tuning in the next week in preparation for the turbo. Good luck!
