    Default How To: Install NEMU Board into B13 ECU

    How To: Install NEMU Board into B13 ECU


    Installing the NEMU Board will require you to solder a bunch of pins and connections. If you don't have soldering experience, practice before continuing! If all else fails JKTUNING offers free installation if you send in your ECU. This is an installation guide if you decide to install the board yourself.

    Please note I have the beta version of the NEMU board, your version will look slightly different.

    Tools Needed
    • Soldering Iron
    • Desoldering Iron
    • Solder
    • Steady Hands and Patience


    Installation Instructions
    1. First remove the top and bottom covers from the ECU. These bolts will probably be stuck, they also strip very easily. User the correct Phillips bit and a drill since your hands are not torque enough and might strip the bolts.
    2. Here is the ECU with the top cover removed. We will be installing the board into the 40 pin empty spot towards the top of the ECU.

    3. You will need to get a desoldering iron, it's worth the $20 and will save you a lot of time and prevent damage to the ECU. Desolder the 40 pins

    4. Push in the 40 pin connector

    5. Solder in the 40 pin connector

    6. You should be able to slip on the NEMU board onto the newly solderd 40 pin connector

    7. Next step is to tell the ECU to use the new daughter board instead of onboard memory. On the back of the ECU there is a jumper that you will have to unsolder move and resolder. Jumper is on CJ1, you will have to move that to CJ2.


    8. If your plug came with 4 wires, pull the right most wire out.

    9. Final soldering step is to solder three Consult wires (Consult Clock, Consult RX, Consult TX) onto the ECU pins.
      Please don't pay attention to the wirecolors, they mean nothing, the location on NEMU means everything though.
      LEFT: PIN 14
      CENTER: PIN 15
      RIGHT: PIN 7



      Soldering these is a pain without a long and skinny soldering tip. Be careful not to solder two ECU pins together or melt the plug.

    10. Now plug in the USB cable and zip tie it inside the ECU to a sturdy place. The diagnostic wheel should do. This will prevent you from breaking the USB port or the NEMU if you accidentally yank on the USB cable.


    11. Install the drivers, and plug it into your computer and upload a base tune.
    12. Put the ECU together, install and have fun having standalone like features in your OEM ECU!

    On the actual ECU, nothing.

    The only difference is that you will have to solder the 3 wires from the NEMU onto the ECU pins as described above.

    This is the hardest part of the install. If you don't have very much experience soldering, it can be very tricky.

    i think i understand now. the header panel is allready there but the three wires are not. so you have to add the wires and just replace the actual board since the header is allready there.

    Updating the first post with some pictures of the NEMU that you would receive if you were to buy one today.

    ^Is that an RJ-45 port? I'd really like to see some more videos in the software. Does NismoTronic come with a base tune for you to mess around with? I plan on getting this RT package but am completely new to tuning so I would like to know what I'm doing when I get in there I'd really like to see some more of your videos on youtube John!

    That is an RJ-45 it is used for onboard inputs to be used with the ADC breakout box.

    John does ship a base tune for your setup, but as he says on the website, it's only to get you to a tuner and get it more fine tuned.

    I am in the middle of reading your build thread Vadim, How have you liked the Nemu and NismoTronic? Are you still using the STI injectors? What MAF?

    I love how nice and organized everything is on your threads, the pictures for everything are especially nice

    I need to get a few more of them with the software in action on the dyno though!

    I've been running the NEMU for a few months, it's been great, I haven't even gotten into more serious features like ADC Inputs, I'm just now starting to touch Ouputs and switched my car from using a MSD Window Switch (VVL Switch) to a using the ECU! Being able to switch cams based on TPS, RPM, CLT, and Speed is very nice too (MSD your restricted to RPM switching only).

    NismoTronic has also been very good to me. It is one of the few tuning software's that support AEM UEGO's. Before I was using Nissan Data Scan for data logging, and then TunerPro. Neither could do the proper Wideband logging, so I had to stare at the gauge as I pressed on the gas... .
    Another thing that really helps is how responsive John is to my feature requests. If I asked for something stupid, which I'm sure I do often, John gave me a good reason why that wouldn't work .

    I'm still running STI injectors and am using the Z32 maf now in preparation for boost.

    Why thank you, I am a little OCD with keeping my threads clean, I wish I was like that with my garage!

    As for the pictures, I go through the extra trouble to help others. I'm fairly new to cars (started really modding cars in 2007), and I found that a lot of informational threads lacked pictures or good step by steps. Thus every time I learn something, I want to make it easier for others to be able to learn the same without digging through as much information as I had to.

    Just soldered part of the stuff today... all i had time for.

    here is a pick of the hardest part of the whole process... the wire connections.



    thanks to Vadim so I know which wires connected to which...

    One more little thing..... Depending on which ECU you have, you may need to reverse (swap sides) with the stand-off closest to the USB connector. The short side is shown on the bottom of the NEMU board in this pic:



    In the other pics of the top side of the board, you can see the stand-off is longer. On my SR20DET ECU, there is no chip under that part of the board, so I swap the long side down and it fits perfectly with the stand-off touching the ECU mother board directly. They just screw together.

    Great write-ups guys!

    Cheers,
    Dave

    Thanks for the write-up!



    I just want to include one more helpful pic, I wanted to be positive of where I was soldering wires.

    Very interested in the answer to this as well. Since the VE ECU is OBD1, I am guessing it should not be too unrealistic to make it work.
    I realize I can use a B13 ECU and make the VVL work with it, but since I already have a perfectly good VE ECU, I would much rather use it.
