Z31 Nistune ECU Tuning[edit]

Question, What is Nistune?[edit]

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.

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

The Z31 will use the type 1 board from Nistune shown below

Installing the NISTUNE board[edit]

I installed my own NISTUNE board into my ecu myself and it wasn't that hard to do with basic soldering knowledge.

First start by removing the 4 screws on both the front and back cover of the ECU being careful as they can strip the heads if the ECU was exposed to the elements.

Next you will need to clean everything that you will be soldering/un-soldering with acetone as the factory covers everything in a lacquer to protect it from the elements.

Z31 ECU ROM Tuning Reference[edit]

The list below shows which ROM set to use as a base when tuning your Z31.
