What you get in the box:

  • MegaSquirtPNP EEC4A8 ECU
  • MSPNP RS232 serial tuning cable, 6′ (USB adapter sold separately, if needed)
  • Tuning Software and Documentation USB Stick with TunerStudio Lite
  • 6′ Vacuum Hose for MAP Signal and ‘T’ fitting

Note: We’re looking for a 2.3 Turbo car as a test mule for a variant of this ECU. If you’ve got an SVO Mustang, Merkur XR4Ti, or Thunderbird Turbo Coupe that we can use for R&D, please email websales@diyautotune.com about your car. We’re in the Atlanta area and would need the test car for a few weeks.

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).

    :

    My son just purchased this for his 88 Thunderbird with a 5.0 HO stock 88 HO cam, SVO GT X heads and explorer intake with a T5. Install was very easy ( less than 1 hour) and the car started right up. The 3.3 firmware did have a bug that caused the car to shoot to 3500rpm for a few seconds, with a simple firmware update to 3.4 problem solved.The only improvement I would love to see is the com port moved to where you don’t have to remove the ECU to plug into it. The car does run better than ever and now we can upgrade cam and injectors and anything else with very easy tuning. Highly recommend!!!

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

  • 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.

Does the MSPNP Gen 2 support sequential injection on Fox body Mustangs?

  • The MSPNP Gen 2 has a maximum of four fuel channels, so it is configured for bank to bank fueling in this application.

What if I have an automatic transmission?

  • The transmission in Fox body Mustangs operates independently from the ECU, so you can use this one with a manual or automatic transmission.

Where's the serial port on this one?

  • The 9 pin serial port on the other MSPNPs did not clear the stock mounting bracket on this car, so we have opted to use a 2.5 mm barrel connector for the serial cable for this model.
