so whats better? Greddy Ultimate E-Manage or Apexi Power FC?

[Sky240PWR]

well is there anyone using these two differnt systems and if so which one do you recomend?..I can get the Power FC for $795 shipped and I can get the Greddy Ultimate E-Manage for $582 shipped, which one should I get?.....I have a RB25DET and plan on making 500whp when done(250whp for now it's pretty much stock right now)

[SHIFT_control]

Ummm, why not step up to $1200 and get an AEM EMS, that way you control everything, not just boost and fuel.

[kuruptR]

Emanage over the power fc. Tuning is a lot easier with emanage...fc's controller sucks nuts. waste of money.

[420sx]

i beg to differ. my friend has FC on his rb hatch and it looks very presentable and tunable

however, i do really really dig the e-manage. and its cheaper too. so if money not too tight u can get FC and if its too much - emanage. to me they are both great products.

[scottie]

Does the Emanage allow you to convert to a MAP? How about the AEM? I am looking into the Hydra EMS as well.

the Power FC is fully programmable guys. And its worth every penny. I am curious where you would be getting one so cheap though... is it from an authorized Apexi Power Excel Shop? IF not you wont have any warranty. You dont have full tuning capability with the commander but it does allow you to make a good amount of changes. Ideally you would want a Power Excel Shop to tune it for you with the PRO software, but since we are few and far between... you could consider the FC-Datalogit software.

Heres some info on the PFC for those that dont know...

[SHIFT_control]

The AEM is a full stand-alone that does enable the use of a MAP sensor instead of a MAF. Comes with its own wide-band 02 sensor as well.

[Brian W.]

The Apexi PFC is also a FULL STANDALONE ECU and if you purchase the D-Jetro version it also uses a MAP sensor, It is plug and play like the AEM. The wideband sensor does not come with the AEM ECU it is seperate. you could buy a wideband and set it up with the PFC like we do.

I run a Power FC on my RB and all I can say, is its worth every penny. The thing just rocks. It learns your engine, to the point that it seeks your mods and adjusts accordingly. It also is pretty much a plug in power upgrade over the stock computer, even with base maps. You will notice a difference, right off the bat. I do not know about the Emanage,but I am sold on the PowerFC.

wtf is with the PFC knocking?
it's been around the longest and remains on top for those who are heading towards a full race setup. Seriously tho, if u have so many questions about it, seems to me you may not be ready for such a huge step...
Anyone I've ever know that had afull PFC setup LOVED it, and would never change/change back to whatever management they had before.

On the flip side, the eManage w/harnesses should be more than adequate for 99.9% of people.

drift freaq: I friggin hate you Dave. LOL!

[trsilvias13]

i would get the pfc if they made it for the KA. The aem ems does not cost 1200 or else i would bought one. they go for around 1700. i checked. i thinking about the emanage too, since i never heard anything bad about that. but i will get it rom tune by scott first then emanage for finer tuning and to run a map instead of the maf

[-usmd-180sx]

+1 for pfc.. Just cause I love apexi

[Happy240sx]

Another PowerFC user...love it.

...and once confortable with it...the commander is quite user firendly. I can rip around that thing no problem.

How does he have so many questions? He asked, "well is there anyone using these two differnt systems and if so which one do you recomend?.."

Anyway, The GReddy Ultimate E-Manage is less expensive and fixed all the bugs they had in their first unit. I would go with the Ultimate E-Manage but that's just me. Apexi is good as well, no knocks but in the end I think it comes down to a money thing. Both do the job well and will end up with the same results.

[slider2828]

Well I use the blue emanage, although it is like the newer blues with a boost controller and the thing rocks. I mean one thing I have to tell you though, wiring takes a lotta time with the piggy back emanage, but they DO make a plug and play harness at mohdparts.com.... sorry to sell them, just a good resource for diagrams and stuff. + I didn't by mine from them. They also have something called autotune out, which tunes your car based on a wideband sensor automatically. mmm other than that it controls just more the fuel, it has MAP hook ups, Wideband hook ups, multi mapping, fuel, ignition and boost controller (with the E-01). But the E-01 allows you to tune instantly, so that is soweet as well.... I like emanage, just more graphical, on the PFC, the commander is a little too small, so gotta spring for the s/w. Good luck....

Point taken...
I worded that poorly. What I was trying to get across, is that PFC, eManage, and AEM's computers are all hardcore systems that typically require professional techs to tune (at least if u want minimal trial-and-error methods of tuning)... they take a lot of work, a lot of wiring, and A LOT of time. What I was getting at, is that if he's ready to take such a plunge, he could definitely stand to do more research, cuz unless you can sit down at a car on the dyno and tune away on someone's car you've never touched... guess what? you could stand to learn more. 2 years or so ago, I sat down with my friend's self-translated PFC manual, and even tho it was in english (mostly) I had a newed respect for guys that can dyno tune w/these management systems... it might as well have been friggin hebrew to me.

It's not about the system. Some are more powerful than others but it does come down to the person who is tuning the car and their familarity with the system. I had Power FC in my car and tuned by someone who was supposed to be a very good tuner but was not familiar with the Power FC nor Nissans. The end result was a expensive tune and a blown motor.

Pick your tuner before you pick a system. These aren't things you want to mess around with yourself if you don't know what you are doing.

BTW, the preprogrammed map on the Power FC are not very good. It's a safe mode to allow you to get the car running so you can get it tuned.

^^^^^^^^
Some very good points here. If you cannot tune your car with a computer yourself, then you do need to find a person that knows the particular setup.

As far as the poor base maps on the PFC go, I have found that more to be a problem with SR's, than with RB's, I do not know why? Though that is what I have seen. All the RB's I know that run them love them, hence my reason for going that way. Plus its a standlone computer, its not a piggyback. With current PFC pricing its a pretty reasonable deal as well. These things used to go for over 1k with the commander. Now you can get them for $750 all day long.

[Sky240PWR]

ok so if I went witht the PFC and controller, what else would I need to make it work?(I know tuned)

[chlatboy]

nothing. It plugs rite up to where your stock ecu should be. just make sure you get hte right ecu for your motor. There are steps you should take when you first install it too. It is so that the ecu can monitor your car and adjusts its settings.

[redsuns3838]

i plan to get a power FC pretty soon too. im not really confident in working with fuel maps and what not...do you think i should just get a used power FC for 300 and skip the commander? and just leave tuning up to the shop or should i spend 600 and get the whole thing new?.

[Brian W.]

im just curious as to where you guys are seeing them so cheap?!?!?!


Personally id get the commander, its handy to make small changes o nthe fly, and GREAT for monitoring things like knock, boost, water temp, etc.


And yes the PFC will learn your car when you plug it in, simply follow the directions and youll be good to go. If you buy a Power FC L-Jetro you can just plug it in, the D-Jetro requires 2 wires be added for the Air intake temp sensor.

[kuruptR]

you can upgrade emanage with a presure sensor unit (map sensor) = no mafsensor ?

[slider2828]

That is correct. The map sensor replaces the mafs sensor... In general, MAP sensors are more accurate in tuning because it measures air pressure in the environment and compares it to the intake pressure. MAFS just takes into account the flow into the intake, but air can be thinner or thicker pending on elevation. MAPS don't have that problem really...

[scottie]

I am a very satisfied Apexi PFC user. I am actually upgrading to the D-Jetro version. I love the features and the fact that you dont have to lug around a laptop like the AEM to view all your engine diagnostics. Furthermore, if you want the Emanage to equal the PFC w/commander, you will end up spending the same amount people because you either have to have a laptop or you have to buy the E-01 Boost Controller to view engine parameters like the PFC commander. Best bang for the buck by far is Apexi. The AEM would be a great choice if you already had a laptop and didnt mind spending an extra $700. This my opinion of course.


-scott

[redsuns3838]

how can you tell if it is L Jetro or D jetro? I sthere a way to tell by the serial number or appearance?

[NZO]

PFC no question but if youre willing to pay more and are actually going to use the additional features AEM is nice. I was looking at AEM instead of my PFC but I really didnt need all the stuff it can do. I'm not even going to get into why the PFC is better but I'll just say, its been around for quite a while and is very widely in use.

Also someone mentioned datalogit, wait for FC-Tune to be realeased if you want even more features and control over your car.

[EchoOfSilence]

what about bikirom?

what is datalogit and what is FC-Tune?

[NZO]

FC-Tune - http://home.comcast.net/~nzo/fctune_info.html
Datalogit - http://www.fc-datalogit.co.nz/fc-datalogit.html

Datalogit is on massive backorder and the manufacturers are very unresponsive. There is a yahoo groups message board for all members but tons of people are unable to access it because the datalogit guys never invite them or reply to their requests. FC-Tune on the other hand is being developed by a very knowledgeable guy in Germany who posts updates every few days on rx7club.com and is taking suggestions and input from users. His box will also be updateable (via flashing the firmware) while datalogit's box is not.
