The Official EMU Tuning & prob thread! Launch control success thanks to fur!

the wide bands dont need to be close to the turbo for the heat as they are heated, they measure gases which will be the same at any point of the exhaust unless there is a leak in the system, hence why shop tuners with rolling roads just insert the probe in the muffler.
i have tried one of the clamps for the exhaust muffler and have really dont like them, the first full throttle run i had out it came loose, i had to keep on tightening it every run, the one time i didn't tighten it it flew out the exhaust and smashed the rear lights. could be sorted with a locking nut but the reading weren't all that great either, again could be sorted by extendingthe probe tube but then why buy something that you need to modify to get it to work right?
according to the EMU manual, it implies that for resonant sensors you use the "normal" setting, whereas for non-resonant sensors, you need to know the target voltage and select it. 7.66 possibly if whats said is right and if there is a target then it's a non-resonant sensor.
personally i use a set of det can's, the ears can tell the differences between sounds, computers just read voltage, det cans can also help you find out if there is something wrong with your car as it acts like an electronic stethascope (sp?)

well frequency is a particcular range where the only data we take from the knock sensor which is good to us.. ie if u leave it as normal ull be getting knock readings of over 100 which is daft & which means ur engine would be toast a long time ago. so by selecting the closest frequency to what the oem ecu reads we remove all the extra "noise" & get a stable knock reading
as i mentioned above its "resonant & frequency is 7.66"

thanx for clearing that up
much appreciated
hi there,
there are so much info after reading this thread and thanks to all for contributing and shares the knowledge to our 4e community
here i have few questions hope to get some feedback from all of u..
1) do we connect all the wiring for emu:
a) injectors wires
b) knock sensor
c) crank angle
d) intake temp
e) water temp
2) in setting up knock sensor, do we use resonant or non resonant setting?
3) does emu software runs perfectly with ms vista?
thanks in advance

hi so heres what i know:
1.) not all wireing is used, from memory from all the points i wired 14 wires.. u can see my diagram on earlier pages..
a.) 2 channel , make sure u have i/j adaptor no.2 & wire that on harness side
b.) knock sensor yes
c.) crank angle yes
d.) intake temp no, use water temp instead
e.) yes (read above)
2.) resonant 7.67
3.) no emu software is not supported by vista..

limits it to what you tell it to, then if high enough will create positive boost whilst stationary, not to mention sounding cool as fook

if u look on the previous pages i posted up a pic of my wireing diagram sorted out for the ep91... if u follow it i can assure u it will make ur life much simpler as it has everything hooked up to it for hte ep91

hey guys, not sure if this has been covered but got a few questions with the EMU.
1. Connecting the Knock signal as the manual. I found that there was two different knock wires (knock 1 and knock 2). and they both share them with intake temp and water temp. How would you go abouts connecting this? I just didnt connect the water temp and connected it to the knock sensor. Is this alright?
** didnt realised but Hybrid did this as well.
2. With the injector connections, did you guys connect injectors 1+3 to #1 and 2+4 to #2??
** what is the injector 2 harness? confused
Ive only got the main harness (A,B,C). Any help is appreciated.
Thanks in advance.

Hey Nick,
So
1.) Forget the air intake temp, connect the water temp & then connect knock no.2 instead as ull find it more important to connect the water temp sensor, especially since to use a/f target ull need the water temp to work
2.) yes thats correct, 2 channel iirc yes thats it one mroe thing though, as iv mentioned before dont forget to buy the injector adaptor no2.. or ull have trouble adding//trimming the fuel

I cant seem to find where to buy injector adaptor no.2
http://www.nengun.com/trust-greddy/e-manage-ultimate
On this site here, they have either ignition 2 or injector adaptor 3?? sorry do you have a link of where I can buy the adaptor? and also, how would I wire it in? will it need to be wired into my ecu as the emanage main harness?
1.what does the injector adaptor no 2 do?
2. I have also read that I need a pressure sensor and harness? Is this correct? If so, where would I be able to buy this?
Thanks again
Nick

Hi nick,
so its simple try www.mohdparts.com thats where i bought everything, u dont need the ignition adaptors, those are for rotaries & boxers
1.) the injector adaptor no.2 shows the emu that the injectors are actually bigger than stock & since our ecu's are a pain in the ass the i/j no 2 allows you to trim the fuel as well not just add.. for wireing, all u need to do is hook it up on the harness about 1 inch away from the ecu side of things
2.) mohd also sell the 3bar pressure sensor & harness... u should find everything there.. u dont really need it unless ull be running more than 14.7psi.

Thanks Kon. Appreciate that.
I was planning to run 16-18psi so I think i need the 3bar pressure sensor and harness. Would that be the "pressure sensor #16401301" and "pressure sensor harness #16401406"?
Thanks again

Thanks again Kon.
Ive tried the launch control as what you did.
So changing the RPM signal type to ignition
and in IGN CUT
i changed it to 4000 (ticked the adj box)
then 7200 rpm
change the throttle position to 90.0
and IGN adjustment to -8.0
and 20 for VS pulse
but launch control doesnt seem to work.
Am i missing something? Ive got an ep82 though so it may be diff to the ep91.
** just realised that ep82 doesnt have a throttle signal plug like the ep91. Would that be why it is affected?
