when are you guys going?

predator666, in my case...stock cooler + 9psi... S-AFC II is around $600....installation and tune is how much? e-manage for me was $900 installed + tuned 12 points vs 16? How much is a 2nd hand PowerFC? $1200? Tuning it? and if I do decide to upgrade, I'm sure the emanage won't have to be ripped out and replaced. Trust have a monster GTR running the e-manage, I don't think my car will get quite to that level though

LOL...erm...get what suits your budget I guess...

Hey SydneyKid, Yeah, each their own. But I think PowerFC and emanage both have their spot in the market place. If you have stock turbo and cooler and just wanna lean out mixtures a bit. Would the PowerFc not be overkill?

Greddy Profec e-01 Boost Controller + emanage??? Greddy Profec e-01 is an electronic boost controller that utilises fuzzy logic and also incorporates a SD card slot to record/playback data. Not only is the E-01 a boost controller, it's also a central data and information system. The E-01 will record data, monitor information on the screen, give you peak/hold/warning features for any data streams it's monitoring...it really complements the E-manage well. Even if you don't intend to program the E-manage with it, it's really a handy tuning aid as a laptop is rather cumbersome to keep in the car and watching at all times! The E-01 can fully control and program the E-manage. With the E-01, you can record and monitor the E-manage's inputs/outputs, tune the various maps, set up the unit, etc. You can save up to 3 maps in the E-01's memory card and rather easily switch between them. In theory, you can have multiple memory cards and swap in different maps. The E-01 seems like a pretty good way to tune the E-manage, but initial tuning should probably be done with a laptop. The E-01 is really better suited for doing "tweaking" to your fuel maps instead of heavy number-crunching tuning. Part of this is just the limitation of the display, lack of an Undo function, etc. The E-01 is also supposed to share its boost sensor with the E-manage - there is an optional cable that goes from the E-01's COM port to the Boost Sensor port on the E-manage. The E-01 can also datalog input from Greddy peak/hold/warning gauges, albeit only one can be connected at a time.

emanage + different AFM's??? One big source of confusion on the E-manage is its ability to let you use different airflow meters. While this can be done, there are some limitations and rules to play by. First off, you can only change an airflow meter for another meter of similar type. For example, if you have a hotwire airflow meter, you can use ANY hotwire airflow meter, even if it's from another manufacturer. The software/firmware only has Japanese airflow meters listed - US AFM's could be used in theory, but you'd have to find its Japanese equivalent. Anyhow, if you have a flap-type airflow meter, you can only use another flap-type; if you have a Karmann, you can only use another Karmann. This option might be helpful for Subaru owners who have had problems with less-than-durable airflow meters - might be able to swap to a Nissan unit, or even another Subaru unit that's hardier. Second, you can't get rid of the airflow meter and use a MAP sensor. Even if you add the optional Greddy pressure sensor, you must still have an airflow meter in the system. The Greddy pressure sensor simply adds another basis for your fuel maps in the E-manage - you can use it to tune your fuel maps instead of the input from the airflow meter (very useful if your airflow meter has run out of range), but that's all internal to the E-manage.

emanage = Apexi S-AFC??? The closest competition to the E-manage is the Apexi Super-AFC. The Super-AFC is a very nice and powerful unit, and they both have their advantages and disadvantages. The E-manage is far more capable, but does require a laptop (or the E-01 boost controller) to program. The Super-AFC is simpler, but is self-contained – you program it right on the unit's display. The Super-AFC doesn't handle larger injectors as easily as the E-manage, doesn't control additional injectors, doesn't do ignition timing, and doesn't have datalogging (though it does do some MAP tracing on the screen, but they can't be saved and are tricky to interpret). It's still a great computer, though. The E-manage is really the next step up.

Larger Injectors + emanage??? The E-manage really works well with larger injectors, and larger injectors are highly recommended. Greddy advertises that you can increase injector size 150% - this is not really a limitation of the E-manage, but of the engine itself. Larger injectors will squirt more fuel at their smallest pulsewidth, and too large injectors will cause idling and running problems. But, additional injectors can be added as well to supplement the stock injectors.

Purchasing an E-manage and E-manage options There are a number of components to the E-manage system. Let's break each one down. E-manage main unit – the main brain of the whole deal. The unit by itself is VERY basic – there are 5 knobs you can adjust on the front of the unit to do a VERY rough fuel map with. E-manage Support Tool – Now we're getting somewhere. Included in the kit is a serial to USB cable and a CD with the Support Tool software. The cable is proprietary, and not a standard cable. The software unlocks the full potential of the E-manage – 16x16 fuel maps, changing airflow meters, using the other optional harnesses, etc. You really need to have the Support Tool for the E-manage to be of any value. NOTE: This serial to USB cable is a special cable of some kind – it doesn't seem to have any advanced logic, but it is weird and special enough that you can't just get one at a computer store. It plugs into your computer via the serial port and into the E-manage with a USB plug. Optional Injection Harness – This splices into the stock fuel injectors for control and logging. With this harness, you can directly add pulsewidth to the stock injectors and datalog their activity. You can also directly control 2 additional injectors as well. NOTE: You can buy JUST the ignition harness and use the extra wires for the injector harness. The ignition harness comes with 12 wires and an extra connector to plug into the E-manage. Most cars don't use all the wires – 4 cylinder and rotary cars especially. Look at the E-manage manual, find your car, and find out how many wires you need for igntion control and for injector control. Make sure to add 2 wires to the total if you plan to use additional injectors. If the total is less than 12, buy just the ignition harness and add the extra wires to the main E-manage plug for your injector harness. The injector harness is just some wires with ends crimped on them that you add to the main E-manage plug. Optional Ignition Harness – This splices into the car's timing input, from a crank angle sensor, cam angle sensor, or the like. With this you can alter the car's ignition timing. Greddy Pressure Sensor – This is a 3-bar air pressure sensor add-on. With it, you can tune your fuel maps with this sensor's output as the basis for tuning instead of the car's airflow signal input. This is primarily used when you've overrun the capacity of the stock airflow meter. Whether or not you need this is a tough question – it's really best to run the car without it first and see if you're maxing out the stock airflow meter signal before investing in the pressure sensor. NOTE: the peak/hold/warning Greddy boost gauge uses the SAME sensor, so you can share that sensor's output with the E-manage. Pressure Sensor Harness – it's simply the wiring harness to plug the sensor into the E-manage. If you're using the boost gauge's sensor, you can buy just this harness and tap it into the boost gauge's harness.

Mostly taken from: http://autos.groups.yahoo.com/group/emanage/ E-manage – what it is and what it isn't The Greddy E-manage is a simple fuel computer designed for Japanese automobiles. The intended purpose is to allow the user to fine-tune the fuel curve of the vehicle to take advantage of various modifications to the car. There are many additional options for the E-manage, allowing the user to put together a system that suits their needs. In its most basic form, the E-manage alters the primary airflow input to the car's ECU. By increasing or decreasing this signal, the ECU will alter the amount of fuel going into the engine. While the E-manage is very powerful and flexible, a full stand-alone ECU is even more powerful. A stand-alone ECU replaces the entire fuel injection system with one that's designed to be easily programmable by a laptop computer. This gives the ultimate in flexibilty, but with a steep learning curve and a LOT of work required to tune in the fuel map properly. It's hard to say at what point it's wiser to go with a stand-alone than a piggyback computer (ie the E-manage) – it really depends on how good the car's ECU is to begin with, the amount of modifications, etc. If nothing else, the E-manage makes for a great stepping stone before going to a full stand-alone – you can learn to tune the car while having the factory fuel map to fall back on.

JimX, this is a good start... http://www.mohdparts.com/emanage/ and probably the best english site about the emanage too... Ed

If you're talking about seperate piggy backs like SAFC + ITC + HKS speed cut etc... then yes it would add up to probably more than a powerfc itself. How much is a PowerFC new? $2000? emanage with all cables etc is around $1000 new. you could get emanage + tuning for probably less than a new powerfc I'm not saying powerfc is bad....but hey, we have a new alternative now and it's not all that bad.

do you drive a merc? :alien:

hmmm...try going to exhaust shop and see how much they'd charge...shouldn't be too much as they'd copy existing piping except use bigger pipe and mandrel bends. ie - they don't have to f*&k around measuring angles and sh1t.

hahaha...kelvin, let me drive it on sunday to show you how it goes...I've never seen you put your foot down!!!

sounds like a good idea though

JimX, exactly WHAT are you getting done for $700? if it's just cooler piping....bejesus that's expensive :eek: Perhaps your turbo needs big boost, might be oversized? Have you done a compression check?

I let mine idle until idle RPM hits 1,000 mark.... Hard for me to drive and stay off boost as I'm on boost just a touch over 2,000RPM

ask sura, he has a NA supra. EDIT: NA supra's would be doing 14's down the 1/4. stock.

JimX, 166 on 12psi is really shocking. Any photo's of the FMIC piping? Has it been on a dyno? Got AFR dyno chart? You're better off doing Front + dump IMO. 180rwkw shouldn't be hard if you're gonna be running @ 12. EDIT: you don't happen to know the A/R on your turbo do you?

LOL....

I was just about to say that

yes...not a worthwhile mod unless your current AFM has maxed out. Also you need something like SAFC with the AFM or a PowerFC etc...as the stock one doesn't understand the resolution the Z32 gives (voltage range). What mods have you done so far JimX? phil, put that flap thingy in your exhaust yet?

exxxxcellent

Ustasa, yep I spoke to Melvin already I was the guy with the white ER34 with carbon bonnet, I have the basic version of the emanage at the moment but will talk to you guys when I have some $$$ MAP sesnsor is optional extra for the emanage or you can hook it up to a Profec e-01 for the unit to sense boost :uh-huh:
