Welcome to Nistune.
The Nistune hardware and software solution provides a means for the car enthusiast to retune their vehicle
whilst retaining their factory ECU and its default programming.
This solution provides many advantages over aftermarket ECUs in that the:
• Factory default tuning is maintained once the NIStune board is installed. Upon installation of the board,
vehicle will be operational as usual.
• Additional tuning can then be made against the factory maps for modifications made to the vehicle.
There is no need to tune the car to get it running from scratch, reducing time and costs of tuning
required on dyno.
• There is no need for wiring loom modifications.
NIStune provides real-time tuning and maptracing. It provides the ability to make changes to the factory ECU
while it is running the vehicle. When the desired results are achieved they are saved permanently to the
NIStune real-time board (in non-volatile memory).
NIStune also provides data logging and playback facilities using the Nissan Consult Port. NIStune software
also provides a user friendly, responsive graphical interface to perform modifications.
Contained in this manual are the instructions for installing a Type 4 NIStune board into the Nissan (JECS)
ECU’s containing the Mitsubishi 7700 series microcontroller. These ECU’s support the use of the “Consult”
diagnostic port – through which NIStune communicates.
