What you get in the box:

  • MSPNP2 Standalone Plug and Play NS8994 ECU
  • MSPNP RS232 serial tuning cable, 6′ (USB adapter sold separately, if needed)
  • Tuning Software and Documentation USB Stick
  • 6′ Vacuum Hose for MAP Signal and ‘T’ fitting
  • Four Screws for ECU mounting

Note: Although there is a paid upgrade to TunerStudio, it is not needed to tune this ECU. The free version included on the USB Stick can access all the features and tables of the MegaSquirtPNP. The paid version of TunerStudio simply adds tuning and analysis software, such as VE Analyzer Live to tune the fuel tables based on wideband O2 feedback (requiring a wideband O2 sensor and controller, sold separately).

Add a review

Is this all that I need to get started tuning my 240SX?

  • The only other potential must-have is that if your laptop doesn’t have a 9 pin serial port, you will need our USB to serial adapter to connect to this unit. However, there are several other things you may wish to add to use this unit to its full potential.
    • If you are tuning it yourself, a wideband O2 sensor system is a must have for adjusting the fuel.
    • Our bolt in trigger wheel kit will allow using sequential injection or distributorless ignition conversions. Single cam KA24E motors typically require a 54 mm trigger wheel, while twin cam KA24DE motors usually require a 50 mm trigger wheel. This MSPNP fits a wide variety of applications and Nissan built many variants of this engine, so please measure the wheel in your distributor before ordering a trigger wheel.
    • This unit can function as a boost controller if you add our boost control solenoid package.

Where is this product assembled?

  • This product is assembled in Suwanee, Georgia, USA.
