1. What are these Nistune RealTime Boards?

Nistune RealTime boards provide a way to make your factory Engine Control Unit (ECU) fully reprogramable similar to aftermarket Engine Control units for a fraction of the price. They use the latest technologies available on the market today to keep the size of the board small and cost lower.

Having your factory ECU reprogrammable means that either yourself or a knowledgeable tuner can quickly and easily retune your factory ECU with minimal installation and setup. They are tuned using the Nistune software. Nistune RealTime boards are details on the Equipment page

2. How do Nistune boards work?

Unlike any other type of daughterboards available for Nissan vehicles on the market, Nistune boards are the only real-time tuning solution available on a single small standalone board.

Once initially programmed, the Nistune board is permanently installed in the owners ECU (engine control unit). The ECU can then be tuned on a dyno via either the USB connector for Type 1 boards or Consult port for Type 2-4 boards.

Combined with the powerful user friendly Nistune software, real-time monitoring, map tracing and tuning is quick and simple

3. How much time will I save using these boards?

Once the board is installed, there is never the need to touch the ECU again. This means no need whilst in the shop, to erase and burn EPROMs after each tune . During a typical scenario, you just plug in the consult plug, start Nistune, load the address file, download the ECU ROM maps and then start tuning. When you are finished, click the burn button and you are done.

4. How much fiddling with soldering wires?

We use the existing consult port provided on Nissan ECUs, so there is minimal wiring required to get your board running.

For earlier ECUs, only 4 wires to the ECU for basic functionality are required. For later model 16-bit ECUs, all is requried is installation of the standard 40 pin connector.

Installation is as painless as can possibly be with a factory ECU. However if you are not experienced with electronic installation, we recommend you either send it to us for installation or take the ECU to an electronic repair shop, with our instructions to get them to install the board.

We cannot cover damaged boards, due to wrong equipment used during installs or user error.

5. Individual License and Tuners License Differences

We have been working with and received quite a number of queries and requests from workshops with what Nistune will cost for the workshop. Nistune has now been split into two users licenses.

(a) Individual users license
- Intended for those who wish to purchase one or few boards, only needing address files for those boards for personal interest
- Limited to three address files, and five differerent ECU IDs that can be tuned in real-time

(b) Tuners license
- Intended for those in the business of tuning. ie primarily workshops. Those who wish to either run Nistune with emluators and daughterboards, or wish to tune using our RealTime boards
- Provided with complete set of Nissan address files with maptracing information
- Unlimited emulator and boards supported
- Discount prices on boards, and further discount on quantity boards ordered.

6. What Wideband support is there?

Currently Nistune supports the following Wide Band units:

AEM UEGO
http://www.aempower.com

DLP Design A/D Converter
http://www.dlpdesign.com/usb/io8.shtml

Innovate LM-1, LM-2, LC-1 and MTX-L
http://www.innovatemotorsports.com

Just Another Wideband
http://www.14point7.com

MOTEC PLM
http://www.motec.com.au/plm/plmoverview

PLX Devices (R Series)
http://www.plxdevices.com

SLC Pure Plus
http://www.14point7.com

TechEdge 1.5 and 2.0
http://www.techedge.com.au

VEMS Wideband
http://www.vems.co.uk

Zeitronix
http://www.zeitronix.com

These units connect to your laptop via the serial port (or USB port when using serial-USB adaptor). These units output data to allow Nistune to monitor your Air Fuel Ratios from their sensor, and some produce auxillary inputs for connecting other sensors which can display and log inside Nistune.

Nistune provides several internal utilities to make the most of your Wide Band
- Dyno Mode graphing against RPM
- Real time AFR and auxillary map display (minimum AFR, maximum AFR and current AFR against the fuel map)
- Logging and playback of AFR

We can add other units in the future, if they have a protocol specification available for us to code and emulate to

7. What else do I need to buy?

If you are using a Type 2,3 or 4 board or are using an emulator with ECUs compatible with these boards, you will require a consult connector. These are available in serial and USB versions from PLMS Developments
http://www.plmsdevelopments.com

You can order our boards through them also! Just let them know the ordering information

You also may wish to purchase a wideband unit. These are listed in the Wideband section of this FAQ

We are not recommending any particular unit, and recommend you research each one based on their own uses and features. Prices vary between the models, and some have additional upgrades for more sensors.

8. Are there any auxiliary inputs or outputs to Nistune?

Nistune provides upto six auxiliary inputs which are read into the PC from your wideband unit. The data from these inputs can be displayed on the Wide Band screen, recorded to the log file with the consult data and played back at a later time.

Nistune does not provide any onboard inputs or outputs at this stage of the project. We may feed inputs using spare ECU connections in the future as an additional enhancement.

9. What boards are available now?

We have sufficient stock of Type 1 - 5 boards available at all times.

    ^ Back To Top



10. Do you stock anything for R33 or R34 Skyline

You have the following options:

ECR33 Skyline (R33 GTS)

Use an HCR32 Skyline ECU or Z32 300ZX ECU:
- R32 ECU will support VCT and TPS idle using updated Feature Pack firmware. We recommend using this ECU for all new setups
- Z32 300ZX ECU can be remapped to run R33 RB25 engines using internal ECU modfications documented on our install pages but some tuners have had difficulty with these units so we do not recommend them

ER34 Skyline (R34 GT-T) / Series 2 Stagea

These have the RB25DET NEO6 engine. Both use the Type 4 board
Non turbo RB25DE NEO engines are not supported, unless using an R34 RB25DET ECU (part number 23710-AA5xx)
 
Series 1 Stagea uses a Hitachi model ECU and does not support taking a daugtherboard (part number 23740-0V3xx)
Note: If the vehicle is manua converterl then you can use an R34 or Stagea ECU in a Series 1

BNCR33, BNCR34 Skyline

Use a BNR32 Skyline ECU with Type 2 board. Using this ECU will require minor internal modification as per our installation guide

13. What do I need for installing boards? Do you install boards?

Installation of boards requires at a minimum:

- Correct fitting screwdriver for opening ECU case
- Soldering station and solder
- Desoldering station or desoldering gun
- Acetone or other solvent to remove flux

See our soldering guide on this site for more detail. However not all people have access to this equipment. Also you can potentially damage your ECU if you have not worked with electronics before. Therefore we also recommend your local electronics repair shop should be able to install the board for you, given you supply them with our instructions.

At this stage, we can also install boards for you. Prices are listed on our ordering page.

14. Can you use a MAP sensor with Nistune?

At this point of time MAP sensors are not supported. We suggest upgrading your ECU AFM to using single or dual Z32 AFMs (dual will require a Apexi AFC) which are the highest reading Nissan AFMs. 
 
We also recommend these days using the R35 GTR MAF slot sensor which measures upto about 300rwkw in 3" tube (or more in larger tube) or we sell the HPX N-1 MAF sensor which will measure upto about 400rwkw in 3" tube (or more in larger tube)

    ^ Back To Top



15. What are the minimum requirements for Nistune

Nistune is written to be as lightweight in system resources as possible. We recommend using laptop with:

- Pentium 500Mhz + recommended running Windows XP, Windows Vista, Windows 7, Windows 8 or Windows 10. Both 32 and 64 bit operating systems supported
- USB 1.0 port or higher
- Serial port / USB Serial Converter: Wideband data display and logging

16. What if I have a problem?

Contact us with some detailed information that is causing you issues.

(a) Type of ECU and board you are using
(b) Error messages and status messages relating to problem
(c) Providing us a log file will definitely help us. Enable File-Configuration-Debug logging. Restart Nistune. Then perform the operations which caused your problem. Disable debug logging and close down Nistune. Send us the log from the directory C:\Program Files\Nistune\logs directory

Firstly use our contact form on our website and then we will get back to you.

17. What are the limits of factory ECU tuning

A single Z32 MAFs can hit a limit of 350rwkw, HPX sensors upto approx 500rwkw (depending on size of tube sensor is installed) and later model ECUs controlling injectors up to about 2000CC using Nistune to control the factory Nissan ECU.
 
Important: Only choose the injector size suitable to your application. While larger size injectors can be used on later model units, they can be problematic if too large for the application. Calculate what power you require, if you are planning to run E85 (30% more fuel required) and then pick the appropriate injector size. Going too large can cause issues with fine control during idle and deceleration.
 
Choose high quality injectors such as Bosch (ID), Nismo, JECS etc rather than drilled injectors (Deutchworks etc)

Note: VLT RB30 ECUs use twin bank sequential/batch injection modes which switch at preprogrammed RPM/load limits so usually a suitable injector is recommended (about 440CC GTR - 850CC maximum recommended). We have run higher (1200CC) but switch points need to be moved so larger sizes should be avoided in this case

18. What parameters are tunable for particular ECUs?

Please see the address files in the downloads section. These have the tables you can modify with each one. You can also open them with the trial version of Nistune to see the maps, tables and values for yourself.

    ^ Back To Top



19. Are the boards lockable?

The latest firmware for the boards is lockable. If you wish to have this, please specify that to us to ensure we use the correct firmware version. The boards use a PIN number to lock the board. Users can connect to the board but cannot 'sync' maps from the ECU until the valid PIN is entered. If the PIN is forgotten or lost, the board needs to be reprogrammed with a base image programmer.

    ^ Back To Top



20. What about an ECU you dont have listed?

We most probably dont support it, or it is only supported at this stage using emulators (see if it is listed in our address file pack). We only support some Nissan ECUs from 1984 - 1996 era. We don't plan to support any other vehicles

We are not working on any FLASH based vehicles (including 350Z, R35 GTR, Patrol TB45/TB48 etc) at this time but looking into it
