Engine Masters EMU Black wiring DIY - Supra 2JZ GTE (automatic) NON-VVTI (J-spec)

Hi All,

 

I thought I would post my notes and documentation for hardwiring an Engine Masters EMU Black to a 2JZ-GTE Non-vvti automatic ecu. This guide may well also help with those wiring other brands of ecu alongside the stock ecu.

 

This is for those that wish to keep their auto gearbox, whilst benefiting from running a standalone ecu to run the engine.

I would like to thank D1andonlyantman for his write-up on installing the EMU black on the VVTI engine, this helped me with my own install despite the pinouts being different.

His thread can be found here: http://www.mkivsupra.net/vbb/showthread.php?355427-How-to-wire-in-a-standalone-ECU-(Ecumasters-EMU-BLACK)

 

 

1st of all, you will have a laminated card with the EMU Black pinouts in the box with your ECU. If not, here it is:

 

 

You will also need the stock pinouts, mine is a J-spec, the pinouts for which are here:

 

If you need UK/ US spec pinouts, they are here also, please be aware the UK and US spec pinouts vary from the J-spec, so the below excel documents may not match:

 

A good source for detailed and easy to understand ecu pinout's is Wilbo's ecu pinout table. Ecu pinouts for the various 2jz ecu's with descriptions can be found here: http://wilbo666.pbworks.com/w/browse/#view=ViewFolder&param=2JZ-GTE%20Engine%20Wiring

 

I created an excel document which details which wires connect to what, please remember to pull any redundant wires out of the back of the ecu plug once you've finished wiring. Or at-least cap them off with some heat shrink. (I found it easier to remove them, as it is far less messy).

 

If the excel document below doesn't work, please comment below or pm me and I will email you a copy.

 

The excel document is attached at the bottom of this document.

p.s. this document is useful to keep if you have another ecu, as many of the pinouts for non-vvti engines will be similar, but it also means you can alter the pinouts to suit your ecu without having to make a new table.

 

I would highly recommend getting a pre-terminated loom as well, as it makes the job easier not having to cut wires to length and install lodes of crimps, with the pre-terminated loom the description of the cable is also printed on the side of the wire, so if you can't remember what a wire is for, you can see it's for ignition coil 1 for example.

 

Following on from D1andonlyantman's thread, I will advise the same as him regarding additional sensors.

Details for which are below:

 

Wideband knock sensor:

Bosch 0261231188 Knock Sensor -

(eBay seller id: gnj_automotive)

(eBay item number: 143143385591) (however this will likely change within a few months as listings come and go)

Wideband knock sensor cable:

Raychem 2 Core Screened Cable (get 5m minimum)

(eBay seller id: s.t.motorsportsshop)

(eBay item number: 202247539128)

 

Wideband Knock sensor connectors:

BOSCH TYCO AMP Junior Power Timer 2 Way Fuel Injector Connector Bosch EV1

(eBay seller id: 3waycomp)

(eBay item number: 141725774390)

 

I would also recommend getting a Bosch wideband o2 sensor (4.9LSU for the EMU Black, or 4.2LSU for the EMU Classic). Stupidly, they don't supply the connector for the sensor, so you'll have to buy that separately: (eBay seller id: jabbersd), eBay item number: 223352768849

 

To install the wideband knock sensors, you will need the 2 core screened cable as mentioned above. on the sensor connector you'll see the numbers 1 and 2. Wire number 1 to the knock sensor input on the ecu and number 2 to the sensor ground on the ecu. the braided shielding around the cable should be connected to a chassis ground (I soldered a length of wire to mine and put a ring terminal on the end and bolted it to the chassis. Install 1 sensor to ecu knock sensor 1, and the other to knock sensor 2.

 

I have included copies of my notes below for further info (excuse the poor handwriting). If you have any queries, please ask below and I will do my best to answer them, and update this thread with relevant information.

 

P.s. if you have found this page and no pictures or documents are uploaded, fear not. I will upload them shortly once I have switched computer.

 

Now for the legal bit: I take no responsibility for any damage caused to your engine or electronics by the installation of any aftermarket ecu following this guide.

 

Best of luck!

 

Kind regards,

Alex

Nice guide, very helpful

Cheers! I Hope so!

Nice one, thanks for putting it together

thanks friend I was desperate looking for this information. thank you very much

 

Hello sorry for my English, what cables have you left so that the automatic box continues to work, with its parallel ecu?

would you have any photo? TPS sensor, speed sensor? I would be very grateful for that information

No problem. You won't touch any cables to do with the auto gearbox. However you will need to splice into the vehicle speed sensor wire rather than cut it. So the vehicle speed sensor feeds both the stock and aftermarket ecu.

 

I will confirm this in the next month and update this thread. My engine is undergoing work, so haven't had a chance to test the gearbox all the way through the gears as yet with the new ecu.

ok, thanks i'm also in process, yesterday i set up a new alternator, which affected my linkg4. and tomorrow I wanted to try the automatic box. I'll take the speed signal for both ECUs. Thank you

No problem,

 

Let me know how you get on.

 

 

So you just splice into the ignition and RPM signal, keep all the auto pins in place and you could, in theory, run any standalone ECU to control the engine?

Standalone has complete control of the engine.

 

Vehicle speed should be spliced as both ecu's need vehicle speed info.

 

The 12v ignition switch would usually turn the stock ecu on. This is the same for the emu black

Hi, today I tested the car. automatic box does not execute well. seems fixed at second speed. i will check the connections

Any update? [GRIN][/GRIN]

Did you splice the speed sensor wire or cut it and wire it directly into the ecu?

 

Following wires can be spliced (wired into the stock ecu and aftermarket ecu): TPS, Cam 1 & 2, Crank pos sensor. The autobox may use the tps and RPM feed (primary trigger I. E. Crank) to run fully. I'm still waiting for a final part before I can test mine again in the road.

Hello, the speed sensor is direct to the OEM ecu, the problem is that I cannot copy signal, crankshaft position. crankshaft position is direct to linkg4 if i splice the cable. linkg4 does not run. Another supra in Spain is running the same configuration, I am waiting for photos of its oem connectors

OK, speed sensor needs to be spliced between both ecu's

 

Your link ecu should be able to run with the crank and cam sensors spliced to both ecu's too.

 

Let me know how you get on. I suppose different ecu's will work slightly differently so may not like splicing, but I've not heard of any issues with splicing before.

 

Im interested to see how the other guy is running his setup if you are having issues splicing to both ecu's.

I am waiting, see the other connections above. He told me he has ecu oem for automatic gearbox and linkg4 strom for engine management. He bought the car with the electronics already

Hello Alex,

 

I need info to install my 2 0261231188 BOSCH knock sensors.

 

Is this the proper way to wire new Bosch knock sensors? As you alteady know, the jdm supra 2jzgte currently has 1 wire going to each oem knock sensor.

1. Does polarity matter with these 2 pin knock sensors???

2. Do I NEED to ground shielding mesh.

3. I am using Haltech elite 2500 ecu. Using the Haltech Plug and Play harness which has the AUX connector for me to connect sensors too.

4. Is my drawing correct?

5. Can I use the factory signal wires to my new knock sensors and use new shielded wires for the grounds?

 

Hey,

Will this pinout work with Ecu Master Classic? 

 

Thanks,

Ed
