Question Regarding Choosing EMU For 2jzge (NA-T)

[2JZNA-T]

Hello, i recently have come very close to finishing my 2jzge na-t project and the only thing i need to do is get my engine management.

Specs of the build are:
precision 6266 turbo
treadstone cast manifold
precision 39mm wastegate
800cc bosch ev14 injectors
AEM 320 LPH fuel pump ( all 6an lines )
adjustable FPR
stage 4 clutch ( clutch masters )
3" turbo back exhaust
TT head gasket
Engine oil cooler

Currently running my stock maf originally in an attempt to see if i could atleast get the car running on stock ecu. Obviously its not running good with the size of the injectors.

So now i've finally saved up enough to purchase my EMU, how ever i noticed the only option for the 2jz is for the 2jzgte. And as we all know the GTE and GE ignition systems are entirely different, my engine runs on distributor based ignition, while the GTE ( twin turbo engine ) runs coil on plug based ignition. At the moment i want to keep my distributor so i know pins have to be switched around but i've never switched pins on an ecu.

With that said, if i place an order for my EMU and specify im 2jz-GE ( NON TURBO ) will you guys be able to make the ecu plug n play ? Or will i have to just buy the GTE version and try to switch pins around myself ?

Im really hoping to make somewhere in the vicinity of 400 WHP, and i've chosen the fuel and head gasket that should support and handle that power with no problem. I am planning on running pump gas, and i just need to know if its possible to have a true plug n play option for my non turbo supra. I do know when i read up on the description of the emu that the US spec supra needs an IAT which i can wire in no problem. i already have the wires for IAT plumbed through my fire wall.

Any help would be greatly appreciated. Thanks !!!

Talk to your lokal reseller and see if they can make you a pnp adapter for the non turbo version.

The only seller i know of who sells the EMU is the ecu masters themselves. And i talked to one person on the team and he said they have to look into it to find out the pinouts of the ecu for the GTE and GE to see what pins need to be switched. And when i told him im about ready to order in a day or two about my situation he hasn't responded.

So at this point i have no clue on what i need to do in order to get my 2jzge working with the EMU. Im hoping i get a response from ecu masters on the situation.

I searched and found one topic regarding the 2jzge but it was something about advancing their timing or something. But not about what needs to be done in order to make it work with the 2jzge.


Seems like there aren't many people with the n-a running this system which is sort of making me question on whether or not i should pass on the emu and go with someone else.

Wich country are you from?

You need a flying lead, wideband and a box. I can get you the pinouts if you want to do your own pnp.

[2JZNA-T]

Right now i have my wideband but its an NGK AFX which has an output signal wire. Hoping its compatible with the emu.

Im from the US, i have pinouts of the ecu. but i don't know how to get a GTE based ECU to work for a distributor ignition. because the Ge just has one ignition output. Where as the GTE has 6. So i don't know how that works out.

I've talked to someone on the ecu master team and they said it will work for my setup. But im just making sure.

I don't think i want to make my own PNP harness. Id like to purchase one from them to add to the simplicity of it.

I was comparing the GTE and GE pinouts and noticed the GE and GTE mostly have the same pinout besides the ignition and a couple other things like AC, trac etc.

just working on exactly like this project including conversion for COP..
which country you from?

[2JZNA-T]

Im from the United States.

But i think our setups would be entirely different because since your going COP, i think you can literally end up adding the pins to the harness for your coils to the IG pins and your good.

Personally what im thinking is the GTE version has the IG for 1-6 so it will be confused when its setting information to send spark but since i don't have coils it will end up just not getting spark at all.

Any of the ignition outputs from the EMU can be set up in the software to run a single coil, you will need to go through and check everything all the other wire connections

I recently learned that when i was reading the online instruction manual. Trying to learn abit on the unit before it gets here.

I also am wondering which pins specifically take the wideband wires for the input signal ? My wideband has a 0-5v signal output just two wires.

But when i look at the pinout diagram it shows a total of four wires for the wide band listed as " WBO" one of them is for the heater so i know thats not one. And the other three are listed as " WBO Vs " ( im assuming that stands for Volt source ? )

One pin is listed as "WBO IP" not sure what that one is for. One pin is listed as " WBO Vs/IP " also no sure what that one is for.

If any one can help me out on that situation aswell it would be greatly appreciated.

I also have to run an IAT sensor, and on the diagram i only see one pin for AIT in, so does the ground of the ait just tap into the " ECU ground " ? or is there a different pin that goes for the ait's ground ? I know the air intake temp sensor is not polarity sensitive so it doesn't matter which wire goes where. I just need to know what pins i need to tap for the AIT sensor.

Thanks

Use analog for the wideband the other inputs are used for connecting the lsu 4.2 directly to the emu. Use IAT input and sensor ground.

[2JZNA-T]

Which one ? There are about 3 or 4 analog pins. Is there any that are specifically assigned to wideband input ?

[PSI-Motor]

Use anyone you like then go in under sensor setup and set external lambda and choose wich input you connected it to.
If its a AEM you full in 10-20 AFR. Innovate is 7.38-22.4 AFR.
Check your guage vs the ecu reading and fine tune it if necessary.

[2JZNA-T]

Ok so for instance if i just wire it up to analog 1 do i put the signal wire to analog one and then the ground wire to sensor ground ?

Ill have to really learn this stuff because mainly i just need the car to run good enough to get it to a tuner.

I have an NGK AFX wideband. i think the max value it reads is 16.00 because its a very sensitive gauge.

Ill have to read the instructions online more indepth because i feel like there is some stuff im not too sure on how to adjust and what not.

Thanks alot for the help so far !!

[PSI-Motor]

If its a NGK AFX type in 9-16 AFR.
Signal cable to analog 1 and the ground of the guage to the same place as all of your power and ecu grounds.

No problem we are here to help

[2JZNA-T]

Ok, So from what im understanding.

My IAT will have one wire going to the IAT pin, then one will go to " sensor Ground " .

My wideband will have the 0-5v input wire go to "analog #1" and the ground wire for the wideband signal will go to Which of the grounds ??? ECU ground, power ground, or sensor ground ? Should i have the IAT share the same ground as my wideband out put ?

IAT is correct. The guage ground you connect to the place were your ecu has its ground. Nevermind the sensor ground. Its just for your other sensors like CLT, IAT, TPS, crank and cam trigger and so on.

[2JZNA-T]

Ok so then the IAT is just going to use the sensor ground.

The wideband is going to use the ECU ground ?

Sorry for the confusion.. This is my first standalone system. Im used to the mechanical side of things like installing turbos and engine components.

But im learning !

Heres a screen shot of the diagram and what i have put down so far.

I wrote in txt NEXT to the pins that are going to have the sensor inputs and grounds according to what im understanding.

[PSI-Motor]

No worries everybody has been a beginner at some point.

Exactly. One to sensor ground and one to IAT in. I don't like to connect the guage ground all the way up in the ecu connector. Just put it at the same place were your ecu grounds are in the chassie.

[2JZNA-T]

So would you recommend i ground the wideband to the actual chassis ? Or should it be in a pin thats listed as a ground ?

In the chassis along with the other grounds.
