By selecting this item - you must send in your board (or board fitted to ECU) for reflashing using a base image programmer. Alternatively contact your local distributor to enquire about reflashing. Postage charges for return of your ECU or board will be added on checkout


Check the list of ECU part numbers below to see if your ECU is supported. If in doubt then contact us first with your ECU part number before ordering!



Features Available in Feature Pack V1: 

Launch control 
Fuel cut, and ignition timing retard functions triggered using either speed or clutch switch input 

Total injection multiplier 
Removes the need for rescaling load in the ECU to make tuning quicker and easier. Tune within factory load scales which resolves issues such as ECU holding onto closed loop when previously rescaling load ranges

Flex fuel support 
Adding full functionality flex fuel and timing maps, flex fuel and timing content trims, and temperature enrichment trim tables). Limited models only

Fan control adjustment 
Nissan ECUs which have adjustable fan output can now control the speed and temperature ranges that the fans are operated in. Limited models only

Minimum MAF voltage 
Some Nissan ECUs contain a minimum MAF voltage which is hard coded. Nistune now provides a parameter for these models to lower the MAF voltage when using aftermarket MAFs

Added VCT functionality 
Adding VCT solenoid functionality to existing ECU hardware, replacing the often unused EGR (Exhaust Gas Regulator) solenoid output. Limited models only

Enhanced tuning simplicity
Remove warm and cold start enrichment tables (only a single enrichment table is now used. Remove knock maps 
(for fuel, timing etc)
