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).

    OMG!!So first off just wanted to talk about the reason why I chose to buy this. Now I did not have this in mind. I saw the price then I was like nope no not buying this. BUT hands down the best investment I have made. First, if you have a Bama chip from American muscle no offense. Just return it. My build is based on a Ford 347 stroker with 36lb injectors along with a forged bottom end. Now, with the stock ECU along with American muscles tune chip, it just would not function right at all. They have sent me numerous amounts of chips, but at the end, they have failed me. so I looked and done some research on this mega squirt and been told by friends to buy it, but I just did not listen I guess. Second, this ECU does many things. It is not your average ECU that does not give you many options. But for me, it was literally taking out my old ECU and plugging this right up. I could do my own tune and not rely on anyone else messing with it. You could tune from anything you ever think of. Whatever you are thinking, it does it! Third, yes it's a bit pricey, but it's well worth it honestly. Also if you want to see my build and see how this ECU works, Follow me on my IG at project.beast_87. Enjoy!

    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.

    You're best off running an ECU from the MS3 family, plus a MicroSquirt to control the transmission. An MSPNP is intended for stock wiring with stock sensors and stock ignition, which does not apply to this build. You're better off with a wire in ECU for this particular application.

    This system was really designed to use the stock ignition and adapting it to alternate ignitions can be a bit of a stretch. I'd recommend an MS3 if you do not already have an engine management system on this car and want to go with a distributorless ignition. There are some options for using an MSPNP like this but they are rather involved. Most such builds I've seen either used an EDIS module and its matching coils, or a 36-1 crank trigger and Hall effect sensor.

    Yes, the tuning software works for Mac and Linux, not just Windows.

    We carry the Innovate line of wideband O2 sensor systems. The LM-2 is a hand held data logging device about the size of a paperback book. It is good for temporary installations where you expect to use the unit on multiple engines. The LC-2 and MTX-L are intended to be permanently or semi-permanently installed on a single vehicle.  The MTX-L combines a gauge and controller in a single compact package. The LC-2 can be run without a gauge or run with a separate gauge. The other differences between the MTX-L and LC-2 gauge variants is largely cosmetic, so you can pick which style best matches your project's interior.

    This ECU will work great for this build - you'll just need to tune it to match the engine's fuel and ignition requirements. I'd recommend adding our boost control solenoid kit so the MSPNP can control your boost levels.
