INTRODUCTION
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.

•ECU covers removal
Tip : The screws that secure the covers will have thread locking compound applied from factory. This is a high strength locking compound so make sure you use a screwdriver with a tip which fits the screw head properly. We use a cordless drill-driver. The combination of quality screwdriver tips available and being able to use an adjustable clutch makes this method far superior.
•Conformal coating removal
Remove the coating from around the header on both top and bottom of ECU circuit board and around SMD jumpers using solvent or contact cleaner (see later in document for jumper details).

•Solder removal
Using a de-soldering gun with a small tip carefully remove the solder for the connector matching your ECU type. This is best performed from the rear of the board.
Adaptor A

Almera GTi, P11 Primera, Late W10 Avenir, Late K11
Micra 98-02.
On W010 (20 pads) de-solder pads 1 - 20
On W020 (30 pads) de-solder pads 2 – 21
Note the 1 pad offset between the two rows.

Adaptor B
S14 KA24DE/U13 KA24DE/N15 GA16DE/B14 SR20DE/A32 VQ30DE/Z32 VG30DETT 1996 - Desolder the W001 row of pads 1 - 40 (outside row).

Adaptor C
ER34 RB25DET / WC34 RB25DET (series 2)
De-solder the W100 row of pads 1 - 40 (inside row)
Autos will have the outside row of pads already used by a board containing auto control circuitry, as shown in this photo. You may need to carefully bend this board towards the ECU wall to obtain clearance.

Tips: The best way to de-solder the pads is to run a line of flux down the row of pads you intend to work on. This will provide a heat-bridge between the de-soldering gun and the solder in the pads. Do not push on the pads otherwise you will damage them – try to hold the iron so it only just touches the pad.
Note that these ECUs use multi layered boards. The middle layer usually consists of ground and VCC copper planes. These absorb a lot of heat and make the de-soldering process quite difficult, due the amount of temperature they soak up from the gun. Heating the area with a hot air gun will help. Apply heat mainly from rear of board to avoid damaging main components which are on the top side. Don’t overheat the board. You should still be able to *just* touch the board.
Ground planes will connect to pads on these connectors, where one pad (pin 1) is VCC plane and two pads (19/20 on Adaptor A boards and pin 39/40 on Adaptor B/C boards) are ground planes. A good quality iron will remove the solder from these pads without a problem, although you may need to increase the time on the pad from the usual 0.5
– 1 second to 1 – 3 seconds.
Another technique is to stand the ECU vertically and use the de-soldering iron from one side of the board and a soldering iron from the other side. This heats the solder from both sides of the pad. This is a particularly effective method but requires considerable skill and is ideally done with help from an assistant.
Warning: Pads on these ECUs are very delicate. Don’t attempt this unless you have the right equipment. It’s quite easy to damage the board. Don’t overheat the pads (about a second per pad is a safe maximum) or damage can easily result. If in doubt get somebody with the right equipment to do it for you.
Check that holes are clear
Hold the ECU up to the light and check that all the holes are clear. If any holes still have solder in them do not try to clear them out using a drill bit! The boards are multi-layer and it is quite likely that an internal connection will be damaged.
If some holes are not clear then reapply solder to both sides of the hole – this helps create a more effective “heat bridge” between the iron and the solder. Then re-attempt de-soldering. It’s usually only pads that connect to power or ground that cause problems.
It is very important the holes are completely clear, otherwise it will make the next step impossible when attempting to insert the strip connectors.
