Greddy eManage

[Tony Starks]

Does anyone use this unit?How does it perform compared to the competition(Apex'i,HKS)?What makes this unit better than the other fuel management units?Thanx

[george]

Tony, i helped a friend install it and run it on the dyno. it was ok but i think the AEM plug and play is better though

[95_240sx]

Greddy's rock, but yes, the AEM's have more possibility, but compared to the price, the greddy is something good to start with.

the AEM's have more possibilityRick

What more possibilities does it have as compared to the eManage?

[big jon's 240]

Has anyone uses the AEM plug and play on a 240? Didnt know it would work.

[Tony Starks]

Are you sure that they make a AEM plug and play for NISSAN?

[big jon's 240]

I didnt think they did either. would be nice if they did, dont really care for the idea of a reprogrammed ecu. (do to lack of adjustability)

[Movingviolation240]

emanage is a nice settup, better than the compitition (when you compaire it to it's real compitition which would be the AFC and AFR) but it can't compete with true standalone because your still limited to the stock sensors and the stock ECU. But it dose give you total adjustability over everything (ignition, fuel, Vtec, ect)

BTWthe Vtec thing was a joke guys...... don't flame me

true, but you didnt mention that with the E-manage, you can use a map sensor, to tune by boost, i think thats an important feature.

[george]

called AEM a while back and they said that the AEM could work with the KA24DE with a little work

[sapix @ RHIT]

that little work is buying the race system that isn't plug and play, so you have to wire the unit, then figure out the fuel maps you need and what not. If you get the race system, it will work with any car, but it is a stand alone in every way you know them. It is more comparable to motec, haltech and all thoses, AEM losing the plug and play, it losses all its advantages in my opinion

[george]

err not exactly, you still have to do some tuning with the plug and play that they package for other cars. just cuz its not packaged for the KA24de it does mean its not a simple instal man. its just means that you actually might have to do some work to make it fit and save a ton o cash and have excellant tech support.

[sapix @ RHIT]

Does AEM have better tech support than other standalone companies?

How much is the AEM EMS?

[ITR_KILLR]

i can see that JWT isn't liked too much on here, but that is what i use, i am about to switch to 72lb inj, (which by the way, the 72lb prog has been reformed and works very well now), since i already have the JWT (had it on the stock DE, so just spent a $100 to have it reprog. for DET), i think I'm going to add an AFC to fine tune with.

[Tony Starks]

E-manage, you can use a map sensor, to tune by boost

So does that mean you wouldn't need a boost controller with this unit?

[george]

AEM has excellant tech support they will spend some time on the phone going over stuff with you and answer all questions they also explain why they recommend certain things. if you call haltech or motec they expect you to be some expert.ITR the AFC will be a good addition to your set up, and yes JWT is not liked cuz it is inaccurate, inflexable, and non adaptive but for a street set up its ok

[SSDwellah]

AEM doesn't make any Nissan plug and play applications, and as far as I know they haven't even released their "universal" race ECU. But as someone mentioned, I think the AEM WILL work with a MAP sensor too, so you can tune by boost.

But BTW they are very expensive (~$1500) but if you upgrade often it can be a lot cheaper than reprograms.

[C-Kwik]

I think the E-Manage would be easier for the end user to use. Since it is a piggy-back, it uses stock timing and fuel maps as a base so you don't have to figure out as much. It can be programmed by laptop and can alter fuel and ignition maps (ignition if you get the adapter). It can control additional injectors, and as said above, it can use a MAP sensor to tune under boost when the MAF limits are reached. One of the best features is it's ease of upgrade. Need to change injector size or to a bigger MAF? Just tell the E-Manage what injector size you have and what you are upgrading to and it will recalculate all the fuel maps for you. To change the MAF, you need to let the computer know which one you are using. However, the E-Manage is limited to MAF's that are listed in it's manual. The PC based tuning is supposedly only available to shops that can tune, but some shops to sell it. It can also be interfaced with the Greddy E-01 for tuning and boost control. I've seen the E-Manage sell for as low as $299. The PC cable and oftware is extra as is the injector harness, but for the flexibilty and the ease of use, it is a great value.

[big jon's 240]

I think we all need to get together and start emailing AEM asking them to make a plug and play for the 240, if there is enough demand maybe they will make it. Im not fond of taking the JWT route when i go turbo, i dont want to have to send in my ECU everytime i decide to change something.

[george]

yeah you send the ecu and you send your hard earned cash and you get and crap in return. screww that just go with the SDS route

[C-Kwik]

You can always get the JWT and then piggyback the JWT with the E-Manage. THis is something I may try as I will have the ability to compensate for a larger MAF and injectors without extensive tuning. I can also then fine tune the system. And if I mess up, I could revert back to the base program or even my last setting. From my understanding, the PC program is windows based and has undo features. You can also save programs. Over time, if enough people have similar set-ups, you can easily use someone else's tuning maps. I'm sure other systems have similar abilities, but I truly like the ease of use I see in the E-Manage.

So does that mean you wouldn't need a boost controller with this unit?

No. A boost controller simply allows you to raise the boost by either a simple mechanical bleed valve, or a more complicated electonic controller that opens the wastegate when desired boost is reached.

What the eManage does is allow you to use a MAP(Manifold Absolute Pressure) sensor to sense how much pressure is in the intake manifold. Using the MAP sensor, the eManage knows how much boost the engine is seeing, and you can tune the fuel to compensate for the boost.

With a MAS(Mass Airflow Sensor) system like we have on our Nissans, the sensor doesn not know how much pressure(boost) the engine is seeing. It only knows how much air is flowing past the sensor.

My question is this. If you use the eManage system with a MAP sensor, can you ditch the MAS all together? I don't think you could because the computer wouldn't operate without it. Since the eManage is a piggyback controller, the car's computer is still used.

Yes, the MAF measures flow, but that correllates directly to the amount of boost an engine sees. The MAP sensor function really only becomes effective when the MAF can no longer keep up with the amount of air going to the motor.

The E-manage info I've come across all seem to indicate the MAP sensor as a secondary function, but I'm sure you can run it on cars that run MAP sensors from the factory. Though, I don't think it was designed with bypassing a MAF as a primary fuel controller in mind. It may make it difficult to use the ECU's program as a base program. Tough to say for sure though.

[Tony Starks]

Now that you've bought up the different sensors involved in this process, where would you relocate the MAF sensor after you've added a snail and an inter-cooler?would you put it on the IC piping?before or after the IC?

[ziggy682]

Usually, you put the MAF before the turbo. There's another thread going on discussing the advantages and disadvantages of using a draw through(before the turbo) or a blow through(after the turbo) system.

no you do not eliminate the MAF, you use both MAF, and MAP readings to tune with.
