Post by **RobDET** » Fri Jun 25, 2004 8:14 am

Good things are in store for the Nissan community...

MUSTANG Dyno test performed on a stock 1997 NISSAN 240SX with a prototype 30-1611 EMS.

ems is the stand-alone system right?

and this is how much $$$?

Post by **BoyWonder** » Fri Jun 25, 2004 8:14 am

Wow.

Yes, cost? Possible group buy?

And will this be just for the KA?

Post by **RobDET** » Fri Jun 25, 2004 8:14 am

It's a standalone. It's pretty expensive. Pricing has not been anounced yet that i know of but a comprable system from aem for a honda is around $1400. That sounds expensive on the surface but compare that to a forced induction setup and you come out on the good side of things. close to 40% gains in some places for that price is a deal i think.

It will be avaliable for the KA24, SR20 and several other RWD nissan applications in the very near future. I'm going to get one for my SR Setup as soon as they are released. I'll keep everyone posted on how it goes for me and my S15 T28

It is also truely Plug and play. 10 minutes with the floor pannels and you gain 37 HP without opening the hood. (Assuming you car is stock and the base map is ideal.)

Post by **Gladius** » Fri Jun 25, 2004 8:14 am

Is that much of a gain really possible? If it is, is this tune so radical that the motor might blow?

*sniff**sniff*

i smell a very streetable n/a KA putting down well over 200whp.

It's AEM's own tuners at work. It is difficult to blow a motor with the stock components. I'm from the Honda CRX/ Bseries swap world originally and AEM is VERY highly respected in that community for quality and duribility.

There are also a lot of late model twin turbo supras running around with an AEM EMS and you know those guys... Cost isn't usually an option, and they are still running AEM.

It will be for any 4 cylinder Nissan is what the AEM Tech said.

I want a 6 cyl one.

IB Engine blows up

That's a little too much for an n/a engine running OEM componentry. I would imagine this engine is tuned to live a month using a ****load of timing and alot of octane.

Post by **msaskin** » Fri Jun 25, 2004 8:14 am

I wouldn't be so quick to say that. The base map tunes AEM comes up with are usually pretty damn reliable and it's not unheard of for them to get ridiculous gains even on stock components.

The map that they did that dyno run with is probably meant for 91 or 93 octane, but, you've got to pay to play I suppose

"It is also truely Plug and play. 10 minutes with the floor pannels and you gain 37 HP without opening the hood. (Assuming you car is stock and the base map is ideal.)"

I hardly believe that. MY engines been modified, tuned, and revalved, with cams soon,a nd I put down only slightly more hp than that dyno shows at 163rwhp...and that is suppsoively "stock"...I ahve difficulty believeing a stock KA can produce taht much hp without freeing up other items first.

also, that torque band doesnt look like any of the KA dynoes I've seen recently...*shrug* we'll see ....

are you serious? This is on a totally stock ka24de'd 240sx?

Post by **Nismo_Freak** » Fri Jun 25, 2004 8:14 am

According to AEM, if I have the EMS with their intake I'll have 160rwhp.

Sounds a little outlandish to me.

A KA with an added 2-3 degrees of timing might produce 3-4rwhp more over the powerband, added with fuel tuning you might get another 5whp peak out of it (which is what Chet got I believe). I just don't see a 37rwhp gain over a BONE stock engine.

Post by **MainEvent212** » Fri Jun 25, 2004 8:14 am

well we'll see soon enough

...if so. maybe i'll set a wad aside for an AEM EMS

Enjoy re-wiring your harness to work with it. Only released for the KA's as far as I know.

Post by **sx_coupe** » Fri Jun 25, 2004 8:14 am

The low end torque gain seems outta this world, but i wont doubt it til i see it, looks nice and for 1400 it sounds pretty good if its true.

Post by **teriyakibroccoli** » Fri Jun 25, 2004 8:14 am

and hey! neato, also wont let you pass smog. keep the stock ECU handy. sounds like fun.. for.. 30 hp.

Post by **KDashy** » Fri Jun 25, 2004 8:14 am

Yeah, us californians have it bad for emissions.

Actuially the SR20 EMS has priority right now. The KA one will follow quickly.

They just got an S14 test vehicle that is bome stock. They plugged in the EMS and tuned it and that's what they got.

If you guys want to learn more about it before you assume it's impossible go sign up for the forums at

http://www.aempower.com

Then ask the AEM Engineer anything you want. It's the actuial guy working on the EMS that posts in the nissan section. He can explain better than i can i'm sure.

Man I don't think we're trying to make you out to look like a liar, but those are some DAMN good results. It looks so good, but feels so wrong.

I guess were all expecting someone to "pop" up and falsify your claims.

I'm really hoping someone doesnt say, "Oh yeah, those numbers are corrected for crank hp".

Post by **RobDET** » Fri Jun 25, 2004 8:14 am

Also what specific part is it that you think can be tuned so radically that it will blow up a stock KA?

Timing won't blow up a motor no matter how much you run unless detonation occurs. Do you think it would be a wise business decision for aem to quote a dyno number where detonation was present? They have a reputation NOT to do things like that.

It's obvious from the stock dyno chart that there is room for imporvement. Look how much smoother the AEM curves are.

Post by **Gladius** » Fri Jun 25, 2004 8:14 am

Where did you pull this info from? Was it the AEM forums?

I know man it's just friendly conversation.

I'm just trying to fill in the gaps. It is hard to believe they got this power "free". I alreay posted some of the question on the AEM board. I'll post the replys back there as soon and the engineer answeres my post. (probibly monday)

Post by **TrunkMonkey** » Fri Jun 25, 2004 8:14 am

the stock ecu is very conservative, so it shouldn't be a big surprise to see results like this. some pretty "miraculous" things have been done with the aem ems. in our very own KAT forum, ivan of SPRacing used the ems to set a whp record for the stock KA engine pushing only 13lbs of boost.

imo, it's the best thing to bless the sport compact world since the turbocharger, and it's about time nissan enthusiasts got their hands on it.

I got the replys much faster than i though... Heres the dirt...

Quote »NICO wrote: "is this tune so radical that the motor might blow? I would imagine this engine is tuned to live a month using a ****load of timing and alot of octane." [/quote]91 octane was used on the dyno with absolutely no detonation.

Quote »NICO wrote: "According to AEM, if I have the EMS with their intake I'll have 160rwhp." [/quote]The 240SX had a short ram intake (for all tests).

Quote »NICO wrote: "Is that much of a gain really possible? That's a little too much for an n/a engine running OEM componentry." [/quote]What is more ridiculous? A 1990's DOHC Motor that makes 52whp/liter or a 1990's DOHC Motor that makes 63whp/liter. In my opinion, this is still far from "radical". Especially for a 2001 motor (Altima). Remember, in 1987, Honda was making 100hp/liter on their production B16As.

The EMS tunes ignition timing and fuel (sequentially) with respect to RPM and Engine Load. It can also adjust injector phasing, coil dwell, etc.

Rob,

I take it you got the responses from JP? He's real quick about things

Shoot me a PM if you have a chance. I'm working with JP to brew something up you may be interested in.
