Hey i just heard that the emanange has a password so you cant change the map....is this true....if it is does this mean they have a preprogrammed map for not only 5.6psi but as well as 7-10 psi?

 

No! The E-Manage only holds 1 map in its memory. Any secondary mapping is stored in your laptop. Not stored in the E-Manage.

 

oh ok so then you would have to clear it out and then program your own map.........if this is so then the map you gave me for 8+psi should work for my 9-10psi dreams on the turbo kit? your awsome swinke

 

moved, again

 

AgentOrange:

I assume you are talking about the E-Manage that is included in the turbo kit... and yes you correct it is passworded. Swinke is correct and there is only one map at a time in there, however the map that Greddy supplies MAY or MAY NOT be tuned all the way up to 10 psi. It would depend on a few things, such as... are the injectors maxed out before 10psi? If so, any additional mapping would be useless... Or did they not tune that high just cause they dont have to? The only way to find out is to start datalogging.

phunk, he has the injectors but does not have enough fuel pump to run any higher than propably 7psi. He needs to change the fuel pump, get WB-o2 and probably EGT just to be sure. The n blank the E-Manage and have someone tune it properly. Could maybe run 9psi at that point.

Agent Orange! Everyone who has run up into this thing the way you are has done damage! Find a tuner than can help you onsite and save yourself the blown motor.

 

lol.........

 

Somethin gyou might consider is the eo1 boost controller. I have that on my SRT-4 and I use it to control my emanage. YOu can store 3 maps in it and upload to the emanage.

If you can get into the maps to view them, then you might be able to just copy the same maps into the other space on the eo1.

 

The other devices that have E-Manage controls built in are limited to certain functions. I dont think you can completely redo the 16x16 maps for Ad Inj, Sec Inj, Timing, Inj Swap ect from the other devices. You for sure would have no need for wastegate control on a SC'd setup.

 

The E01 or any other EBC for that matter would be a bad idea for any typical installation of turbo for now. Leave the higher boost up to those that have the means to moniter and datalog and tune their Z's.

BTW the E01 will not let you even view the maps, and it gives you a message every time you turn the car on asking for the password to the Emanage. You can not see what is going on at all without the password.

A customer couldnt pay me to retune their E-Manage cause I already dont even like the thing in a 350z. Its not really the way to do this in my opinion and I am skipping that part in my 350z and going straight to better things. Once I have that all set away I will offer it to others as a solution to run more boost properly. IMHO the E-Manage is a hack in cars with MAF and puting the MAF in a charge pipe is a hack IMHO as well... Ultimately I think the Greddy system should work just perfect for people running the lower boost, such as 7psi or less, but after that you are just missing out ont he oportunity to properly tune if you are still relying on that Emanage.

 

I agree with the MAF issue. That why the few of us who own E-Manage units have install the opt. MAP sensor. Who is running there E-Manage on a 350Z with any mapping being followed by MAF settings? Nobody I know. You need to play with the E-Manage a little. I am sure I could go to much higher levels of performance with the E-Manage, no problem. What better things do you know about to replace an E-Manage? I would like to know and have that option also? What diff does it make if you use the E-Manage for low or high performance, all it does is calculate numbers and dish out control signals. I didnt know the E-Manage had it own opinion when it switched into HP mode. Youve aperantly not had the E-Manage hooked up with a laptop yet. It works great. Please do be more specific about your complaint on the E-Manage so I can learn something. Just putting out general "blah blah blah" about a product is not help to anyone.

By the way, we all know the MAF is useless WOT/5Krpm and up. Thats why all tuning has pretty much been done on MAP!

By the way phunk I hail from Tinley Park. What shop do you own or work for in the GC Area?

 

In the past, Greddy HAS password protected their E-Manage and no, they will not release the password. Not sure what they have planned out for the 350z kit though.

I have used the e manage on my old 97 eclipse turbo and it worked wonderful. I bet it will work just as well on the 350z with some 440 injectors and a bigger fuel pump. I also did not think tuning it was that hard when using a wide band O2

Darryl:
I know you guys are using it on your car and also know you know more about it then the US greddy guys too. would you say my statement is true or are you guys having a hard time with it on the 350z?

 

spazpilot

So far so good! The E-Manage is doing everything we want it to do. Right now we're just limited by the original fuel system. Once we've got that worked out, I'm sure the E-Manage will take care of the rest. As well, I'm running the E-Manage on my own 2G DSM as well!

Darryl

 

Darryl:

Thanks for talking to me on the phone today. Hope to work out something with the fuel system when I get the setup going on my car!! CJ

 

swinke, i have lots of experience with the E-Manage utilizing both the Greddy MAP sensor and laptop software. Cars ranging from MR2s, Hondas, to IS300s.

I wish you the best of luck with your project. Nothing is especially WRONG with the E-Manage, just not the way to do things when your as picky about how your car runs as I am. I am sure it is well suited for those who accept its methods, but I am personally in a situation where I have the means to deal with higher end products and that is what I wish to put in my Z at the moment. Perhaps I will play with the E-Manage in there as well, but at this point in time I have no intentions of this whatsoever. Ill keep everyone updated with my project and to those of you who prefer the E-Manage... more power to you, I just personally dont like it.

BTW one of the largest flaws with the E-Manage is that it can only let you run larger injectors with an airflow correction factor. The larger the injector, the more the correction. If you know the game your playing so well, then I am sure you know what effects this has on the car. I wont say you cant make big power with it, you can make all the power in the world with it... but there is a lot more to tuning then full throttle... at least to me there is. Try putting some 660cc injectors in your Z then tell me how much you like the E-Manage.

what about using the secondary injector function of the E-manage? From what I can tell, many people are against running a second set of injectors, but I'm not completely sure why this is the case. It seems to me that a piggyback controller that has MAP information as well as the duty cycle of the primary injectors would easily be able to figure out how much to spray secondary injectors to realize a correct overall fuel spray and a proper A/F ratio.. but maybe I'm giving the E-manage too much credit. GReddy's online docs for the E-manage are worthless, and I can't really get a good handle on how capable it is without actually seeing one and reading the user's manual.

Your thoughts?

(I wish I could use an HKS F CON as well, but I refuse to leave my tuning up to someone else, no matter how much I trust them. I've seen too many botched tuning jobs.)

 

azrael: Well that was my entire plan...

The problem is that the E-Manage cannot fire 6 sequential secondaries.. therefore you could not just do a secondary rail, you would hve to put the secondaries in the charge pipe. The problem with this is getting proper fuel distribution between the cylinders and proper atomization, this could be very possible but I personally am not gonna be the one to do individual cylinder datalogin just in ATTEMPT to run some seconaries. OR you could just leave the E-Manage alone and run a Rebic AIC controller and a pair of secondary rails... which is an option.

What would I do if I were someone who wanted to try and use the E-Manage? Well I would experiment with different setups. The less injector correction factor your running, the more the car will drive like it should given proper air/fuel.

Please dont use this as any type of guide because I have NOT tried this yet, this is just simple where I would start playing around if I were to attempt the E-Manage, and perhaps I will for the more budget minded.

I would probably attempt a setup utilizing an upgraded fuel pump with a return line system and a 1:1 standard fuel pressure regulator. I would try the 440 injectors, and idle/vacuum fuel pressure a little below stock, so that the closed loop cycle can properly handle the extra fuel with ease with as little injector correction factor in the E-Manage that I can get away with. At this point it wouldnt be a bad idea to just tune the car as is without any boost, just to get your vacuum and driveability all squared away with this new setup. TO AN EXTENT I would always prefer to drop fuel pressure than to use injector correction. I would rather start lean and use the additional injection map to richen it up, rather then to start rich and use the airflow (injector correction does this) to lean it.

If you ask why I dont like the injector correction factor or playing with airflow readings... well... all those years and years of R&D and research Nissan did on ignition timing control for your engine... you can throw it out the window if you have any airflow corrections going on. Yes the car will run, and maybe YOU wont notice the difference.. but its not uncommon for people to blow their engines not imagining how much they advanced their timing by trying to tell the ECU that its running lower airflow.

From here, it should be possible to get the car running very good outside of boost. As for boost, heres where I would take it. As rediculous as this sounds, I would probably toss in a Rising Rate FMU, such as the Vortech, and I would start with a 6:1 or so spring. WTF would I do that? Well, a 440 injector IMHO is small. Sure bigger would be nice, but its easier said than done getting a E-Manage car running well with extremely oversized injectors. Not to mention what I said about airflow correction. I would put in this FMU only to ASSIST the itty bitty 440s since it is a boost only factor. Basically the FMU will increase fuel pressure by 6 psi per every 1 psi of boost. This means it will take far less additional injection mapping to get proper airflow... and therefore I will not reach peak duty cycle until higher boost levels. If the 6:1 had the car running rich without any add. inj. mapping, then I would put in a smaller spring. I would want the car to run just a little bit lean with just the FMU, then pick up the extra fuel thru the add. inj.

Rigged? You bet, but I bet it would work. Maybe Ill try it out in the Z.

I actually have an interesting Honda Civic at my shop that we bult for a customer and we are testing this exact setup. I will have it on the dyno to attempt tuning as soon as I get the machine up and running at my shop... I still have to excavate the ground.

 

Charles --

I didn't realize the E-manage couldn't handle 6 sequential secondaries. In that case, the E-manage is useless to me as well. I agree 100% that doing injector size correction is a kludge, and it's not the solution I'm looking for.. I'm looking for something quite a bit larger than 440 injectors anyway. The rebic AIC is an interesting possibility, although I'd just rather use a nice standalone ECU.

It's really annoying that there are no good ECU choices for the VQ. I'm a huge fan of the EMS and the PowerFC, and I'm praying one comes out for the VQ. Given my financial situation, I suppose I have the time to wait.
