What have you guys heard about the Greddy e-manage piggy back system? I am getting the GReddy Profec e-01 and it comes with all the e-manage capabilities. From what I have read it has the ability to control air/fuel ratios, does anyone know if I will need to get the apex S-AFC if I get the Profec e? Thanks for the input, things are getting a bit complicated.

wing240 has been using it for a few weeks now. You should PM him with your questions.

 

The profec e-01 is only a boost controller so, yes, you would need an Apex S-AFCII, HKS AFR, greddy e-manage to control fuel. That advantage the e-manage has is that it can be controller through the e-01 and also through a laptop. You can also print fuel data and save things on a SD memory card.

 

ive got the profect e-01 & e-manage combo, but yet to be installed. its a nice little set-up. most the capabilities of a standalone, but piggyback style.

 

CoolGuy949: The PRofec e-01 Comes with the e-manage piggy back system, thats why I dont think that I would need an AFC, sorry I should have been a little clearer in my last post.

rt turbo: I am very interested to hear about how you install yours, I have heard nightmare stories about the install because of the lack of a standard harness. Did you buy the optional additional features harness? Its interesting that they would make a harness for the special features and not for the boost controller itself??

no, the emanage does not come with the profect e-01. it can hook up to the emanage with a standard usb cable. the emanage is like $380 or so. if your getting the profect e-01, get the emanage. it has much more options.

btw, i did get the optional ignition timing harness &injector duty. its a must. you can correct for the stupid dip in timing everyone has seen on the dyno.

 

I've been looking at various piggy-back ECU modifiers and it looks like they all do about the same thing. Namely they intercept the signals that control the fuel delivery and allow the engine to run a bit leaner or richer as required to get more power/safety.

I wonder if anybody could explain the significant or material differences between say, the S-AFC, XEDE and The Greddy e-manage. Why should I choose one over the other? I'm considering buying and installig one of these along with an EBC of some kind (probably the Blitz SBC id or the Greddy profec B-01).

The big differences I think I see are basically of price or style. Am I wrong in assuming that any of these fuel controllers would give me the same results if properly adjusted? I'll be sure to use a dyno and a wide band O2 sensor to make sure that no dangerous adjustments are made.

Another question is do I need a separate boost gauge than the one integrated in the EBC? That is another point of controversy as the available boost gauges for the EVO a few and look pretty crappy. Even the factory unit looks like crap and I don't like any of the alternatives either......

Thanks

 

well the safc just modifys the airflow signal. the gredy e-manage does 16x16 Airflow Adjustmemt Map, Larger Main Injector correction adjustment, Upgrade Air Flow Meter adjustment, Boost Limiter Cut, Anti-engine Stall, VTEC-fuel adjustment, Real-time Map Trace, Real-time Display, Real-time Communication, and basic Data-logging, with the "Optional Injector Harness" and the software, the unit has the ability to control an additional 16x16 Injector duty cycle Map and the Controls for adding up to 2 Addional Sub-injectors. If the "Optional Ignition Harrness" and the software is used the unit has the ability to control a 16x16 Ignition Timing Map, If the factory range of Map or Airflow meter is surpassed, you can incorperate "Optional GReddy Pressure Sensor and Pressue Harness" to set larger scales of ajustment... this is a great feature, you can change the mas air flow sensor out.

the emanage is on a different level than the safc, it hooks up to the profect e-01 and is controlled through that or a lap top. it is basically a stand alone that uses the exhisting sensors.

 

Thanks rt turbo, this is a lot of good info. I definitely will not go with the SAFC if the e-manage is so much more powerful and it's actually cheaper I guess it's also a viable alternative to the XEDE from Vishnu performance. I have a chance to get the GReddy set up of e-manage plus the EBC for a very competitive price, I also have an opportunity to obtain the HKS exhaust at similar savings. The whole thing can be installed and dyno tuned as well so I'm very interested in these mods. What's your opinion of these modifications?
The only concerns I have (very valid ones I think) are that trhough some chance my car could end up performing poorly or suffering some damage that later can result in denial of warranty. I just don't have the personal experience to tune the car myself with these devices. I guess I'll have to investigate thr skill of the tech who will be doing the job and trust their work (as I look over their shoulder..)
Can you give me some tips or warnings as to what I might be getting into? I'd surely appreciate it.

Thanks,

 

im not surte about the XEDE unit, but ive heard good things. the best being it is very easy to unplug and run factory settings. this is why im buying a ecu harness "jumper" so it can be disconnected easily. if you arent sure about the tuning part, its best to get a profesional to do it on a dyno. you will thank yourself afterwards whe the engine isnt blown. this is a very touchy thing, messing with engines, you have to know what you are doing, and be good at it. but thaqt doesnt mean you cant have someone esle do it. theres no reason one shouldnt be able to experience the power just because he doesnt mess with tuning often. just remember to check, double check, and triple check your work. also, your engine will run differently with regards to the weather. the turbo might spike boost if you tuned in warmer weather and it is cold outside, just make sure to watch the gauges for engine vital signs all the time.

 

Just got the E-01 and e-manage, but haven't tuned it yet.

Any ideas on some minor tweaking, but not too agressive?

 

You gotta go to a dyno equipped facility to get the most out of your set up. Unless you know a lot about what you are doing, messing with the fuel tables could harm your engine....

 

Looking for a four wheel Dyno in Central Texas. Any ideas?

 

I just got my emange in also - I am running a 7 - 10% air flow signal cut on 100% thottle from 3500 - 8000

That seems to work ok just to drive around till friday when I can get on the dyno to tune it leaner and advance the timing

 

Hey Al, please keep us posted..... Oh, BTW, did you get the XEDE too?

Thanks
