E MANAGE ULTIMATE! (lots of questions)

[turbo2nr]

i just purchased the EMU(emanage ultimate)

im wating for it to arrive but im reading up on the features and how to tune it.

quesion one: fuel triming

im not to clear on the channel function, and whats it used for. i understand that you input the stock injector size and the new injector size and it will correct. now if i wana lean or richen it out what do i have to do? also in the reading material it shows 6 channels, im assuming we only use 4 because we only use 4 injectors? and whats the +/- value about, how does the EMU determine how much more or less fuel to use?

question 2: timing

how the hell to retard timing? do i set a base point and tell the EMU to pull .6 degrees for every psi after 4psi?

the whole channel thing is confusing to me.

quesion 3: wideband o2 installi have a aem wideband how do i install to the EMU, the aem has a serial wire, i know i have to use the same ground and the serial wire, but do i need to buy another harness or some thing?

please help me not to blow my engine up.

also from what i read so far the ka24de is not an option in the engine selection. what engine to use? i have seen some people use sr20 and just change the displacement to 2400cc. or am i mistake and the ka24 is there? what do i configure the emu to see?

thanks

no emanage love?

You're one of few running the Ulty version. Chezdik runs the Old Blue, he may be able to help out. I've read up on the Emanage, but haven't tuned one...

[ZUL8R]

I hope we get some responses here. I bought one too and its not in the car yet. But i do have the same questions u have..

[WDRacing]

I'm reading up on it right now...I'll have some answers in a few.

[turbo2nr]

well at least were in the same boat,

good website : http://www.mohdparts.com/emanage/

scroll to the middle and it has a emange ult. instruction booklet.

so far form what i gather you tell the emanage that you wana add or subtract fuel in the main setting. then after you have the car dialed in the main setting you go to the maps and fine tune.

for ignition same concept, the whole channel idea throws me off, i think channel = injector. use up to 8 injectors i assume because you have eight channel. i think its cool that you can make it seq. firing. but i have question on how to set it up.

as for the wide band , the aem i have has a seiral wire and the attachment for the emanage air fuel has a serial cable. form what i understand you link the two serials cable and use the ground form the wideband. after that you can use the self tune option which will help with achive set air/fuel. and they you fine tune.

form what i find its not to bad but i need to read up back on my efi tunning articles and learn more about it.

the air fuel i guess i have to log and look at the log and see where it needs to be altered.

i think the two key things need to tune the factory map well is the knock meter attachment and the wideband attachment. with these you can fully tune the ignition and fuel maps to the most accurate.

Thanks bro, i really need to install the E-manage. I have an ECU and a SAFC-II in there. I need te Ultimate to pull or add timing. I m pushin 18psi right now which really calls for the E-manage..

There is an injector scaling map in % which can go positive or negative, and you can also adjust the maf output like an AFC. You will only use 4 of the injector channels but make sure you hook up that ground wire, otherwise the car will not start and you could be chasing your tail for a while. The value is just a straight percentage of what the ecu is telling the injector to put in. You can choose your y axis (vs map or airflow or some other things) in order to scale them for your specific setup.

the whole channel thing is confusing to me.[/quote]There is a 2d map here and you can adjust the timing vs rpm and load. It is similar to a stand alone setup except it is only a modification map. You will only need one channel if you are using the stock distributor, the other channels are meant for a coil on plug car.

There may be the KA24 in the new version of the software which is available on mohdparts.com

thanks chris!

i did some more reseach called greddy and talk to a tech. he told me that the newer version has ka24de as a choice for setup.

thanks for clearing up the whole injector tuning aspect.

another question, is their a way to get the emu to stay in open loop, i was reading about a aux. map that you can ither keep the car in open look or use it as a vtec control?

chris have you tuned emu at ams already? are the results good?

also the ground you speak of is a ground internally on the jumpers or externally on the harness hook up.

thanks for the responses.

I have not messed around with getting the ECU to stay in open loop. When the car goes full throttle it should be open loop. In order to do it all the time you would need to do something to one of the sensors that allow the motor to go into closed loop. o2 sensor perhaps? I'm not an expert on the inner workings of the nissan ecus.

I tuned mine for 75lb injectors and an intake on an otherwise stock car. I liked the functionality of it. I had to take it off in favor of and AEM EMS becasue my car was being used as a test mule for the shop and the turbo kti and all of our other parts. I think it would have worked well, although I can't tell you for sure.

The wire for the injector grounds is listed on the emanage diagram with the other injectors, it is easy to over look it, which is why I mention it. I initially forgot this wire and the car would not start. After a little head scratching and looking back through the diagrams I realized that I had missed the ground wire, hooked it up, and the car fired right away.

thankschris

[turbo2nr]

so your talkin about pin 118 on nissan ecu has to be grounded and sent to the emanage. comrrect?

i was also thinking about the ignition map, i was going to pull timing back .6 degrees for every psi, but you have to do the ignition map by rpms vs load. so would it not be hard to pinpoint when boost hits at differnt load to start putting in a negative value for the timing retard? because on differnt load (throttle possition) and rpms boost acts in quicker or slower, so i dont want to be to be pulling timing when im not making boost. e.g im at 4000rpms 40% throttle, ignition map calles for 4degree timing retard, but im not in boost, am i still going to have a 4 degree timing retard? i guess i have to set the load map very carefully. i was wondering if their is a forumla or method of caculating this correctly.

i feel like such a noob again.....

1) Changing the after/before injector size will change the correction. So if you are having issues getting the car to run stoich enough to start and run. Then you tune.

you will be able to lean or richen using the airflow maps, or additional injection support. Also, I think that the new Emanage will allow you to tune pulsewidth. You have many more methods of fuel control than I have in Gold.

The channels are the number of injectors you can control. In Blue it is the number of 'normal' injectors, then you can add a sub-injector map. They have to be the same sized as the other injectors, but it can be done. I would not be surprised to find that they have done away with this function in Ultimate, since it becomes much less necessary when you are running injectors directly, rather than just 'tagging along' like Blue does.

2) If you have added the MAP, I believe that EMU allows you to pull timing based on boost pressure. Don't expect it to be in PSI. In Blue. they use the Y axis (Load axis) in kPa, this is very helpful but I can only assume more so in Ultimate.

3) for the input to log the WB02 in EMU, you just need to get the 2 wire adaptor from mohdparts.com and use it in one of the 'boost' ports.

As far as engine selection, you will not have an option for KA24DE, so you will have to use the SR20DET and change displacement. Then you will need verify that you are using the right MAF.

Hope that helps.

Check my Sig.

[turbo2nr]

thanks chezedik, it helps, hopefully ill be using the emanage by the end of the month, need to get the turbo in. i was talkin to greedy tech. the emanage will have the ka24de as an option. so were good on that.

i guess ill fool around with the damm thing till i get it right.

[WDRacing]

Just for my reference, how much is the Emanage Ultimate with all of the bells and whistles. I'll be adding this thread to the FAQ.

WD

[turbo2nr]

emanage ultimate - $460-$540 (unit only)e manage ultimate harness - $90air fuel harness -$25pressure sensor- $99pressure sensor harness- $30usb cable - $10

good emanage website for hanress and info:http://www.mohdparts.com/emanage/

fyi there is a harness that sells as a direct "plug and play" its $270 and it includes an air fuel harness wired in.

hope this helps

if you take the time to read the instructions given with the emanage its pretty straight foward, some parts you may have to read twice or three times but if you actually think about it, it will make sence.

ill hopefully be doing a full tunning write up when mines is in and working.

[Chezedik]

Do you have a base? Also, does EMU use GSC files? Have you checked my sig?

[turbo2nr]

ya the sig is helpful. when i searched i didnt find much on ka24 motor. but the group is help ful in general.

as for the other to thing you asked for can you explain more what you mean?

[Chezedik]

What other thing, about the GSC's or about ir about the spam free group?

[turbo2nr]

gsc, not clear on what you mean. still a noobie untill i actually tune

[Chezedik]

GSC is the file suffix for Greddy Support Tool Configuration files, at least for Blue/Gold. I was wondering if it uses the same format, but if I recall it uses EM2 files. Have you been playing with the software.
