Aem Ems

Does the AEM EMS really make a big difference ,what does it do and how much HP can i get of of it???

THe AEM Ems is designed to help you (read... a prfessional) tune your cars ECU to get the most out of the mods you have installed. It is only going to make itself worth the cost if you have done some serious work to your car. We are talking like a turbo at the minimum or some serious internal work. Other than that it is not worth the money. THere is not that much you can squeeze out of a stock honda without decreasing the stability and relibility of the vehicle.

Couldnt have said it better myself Doubletap. The EMS isnt there to "make power" its there to free up the power you have by adjusting ignition, a/f ratio, etc. Also if you get it your going to have to spend a few hundred more on getting your car dyno tuned if you want any real gains out of it, so save up for that turbo first.

actually it does make power, by optimizing the fuel and ignition. freeing power is power you had all along but is/was used by an accessory or something(ie lightening the flywheel=freeing, adding cams to control air=making)

you dont need turbo to get a stand alone ECU. simple mods that change the timing or fuel/oxygen(ie cams, pistons) will benefit from a aftermarket/tunable ECU. if you dont know how to tune, skip the AEM and go for a Hondata or Uberdata. theyre much cheaper than the AEM because they dont include the hardware needed to change the maps. with the Hondata/Uberdata the tuner should have the hardware to tune them.

[civickiller]

ive heard that some hondata tuners dont like to tune uberdata, simply because it will take them longer to tune with uberdata than with hondata.

[GScivic7]

With uberdata you have to reburn the chip after every adjustment that's why.

[Kven]

im not too familiar with what goes on but cant you just use a romulator(aka emulator) with uberdata? thats how ive seen most hondata's tuned,

[civickiller]

i dont think you can use a emulator with uberdata. because someone told me the same thing. hondata tuners use an emulator but then nobody came back and said oh but uberdata can use that too. so my deduction is that u cant use a emulator with uberdata. i dont see why it wouldnt work

but then again, i may be wrong

Well I am not sure about the general opinion of eople on this board but in my book "simple" mods include things like a cold air intake or a cat back exhaust. I would not consider a cam change or new internals (high compression pistons etc.) simple mods. They would be moer on the level of serious adjustments like a turbo, just on the NA side of things. THe truth is that the simple mods really are not going to get the real benefit out of a programmable ecu and even if you are changin the cams and poistons they willneed to be drastic (stage 2,3) changes to validate the expense of a grand pluss on a programable ecu when a hondata will work just as well.

On another note... optimization is not making new power it is bring out potential power that was already there so it is in effect freeing up power the exact same way a lighter flywheel would.

[Kven]

i didnt mean simple as in simple to do, i mean simple such as just swapping out a component for another unit. but imo doing those arent hard at all, just time consuming.
some "simple" mods that can change fuel/air includes a intake manifold,fuel injectors, header, etc. they arent hard to install, but they alter the fuel and air, and if the engine is tuned to work with them then more power can be had. will there be big gains? no, but youll be making more power then before.

you're right, optimization brings out potential power, but if it was "potential" then it wasnt there yet. a lightweight flywheel; the flywheel is using xxx amount of power from the engine so it decreases the power that makes it to the wheels. but if the engine is making more power then before, bringing out the potential power, the flywheel will still use xxx amount of power, but since theres more power being produced, more power gets to the wheel.

think of it like this; what components are involved in making the actual power? -> Air, Fuel, Spark. if you can get those to mix/fire better then before, youre making more power. the ecu can control fuel and spark, nowhere is the flywheel part of that process. all of the power comes from that combination of air/spark/fuel, which is where the absolute peak power is made, but as that power moves out towards the wheels, power is loss along the way. the power made from that is also used to overcome friction within the engine, turn the countershafts on the crank, turn the flywheel, etc. if you lighten or reduce friction in the components that "use up power", then in a sense, power is freed.

[Doubletap]

Ok well at this point I think we are arguing over symantics and in the end we agree on the point of this forums as to what an AEM EMS does and whether or not this guy needs one so I will let it up to the individual reader to decide whether they like making power or freeing power as their preferred terminology.

so the right question is, what kind of mods does he have ? what are his plans ?

Exactly, because if his car is stock right now then that $1500 or however much those damn things cost could be spent on other things that will give him more hp:dollar... Like a bunch of stickers or a huge wing...

[cubanpapii]

what i have now is greddy evo exhaust and an AEM V2 intake, but in
the very near future(1month) a superchager will be in there...

[civickiller]

what kind of supercharger ? one that comes with fuel managment already ?
