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). It also unlocks the ability to use customized dashboards, such as our MSPNP2 Dash, which is designed specifically to help make tuning your new build intuitive and easy!



Taking it to the MAX?  Two great things that go great together on this Miata/MX5:
MSPNP Gen2 and MaxSpark PNP!!

MaxSpark PNP Ignition System for Miatas

The MaxSpark PNP High-Performance Ignition System for the Miata is the perfect pairing with this ECU!  We took the ultra-high performance IGN1A Ignition Coils, designed a bracket to mount these coils on the NA/NB Miata engines that fits these motors perfectly and looks good doing it, built a wiring harness that’s almost too pretty to tuck, but designed to tuck it is, and included plug wires as well.  It’s everything you need to quickly and easily install the hottest ignition system available on the market anywhere, for your Miata/MX5.

  • Super Easy PNP Installation.  Unbolt your factory or inferior aftermarket ignition system and bolt ours in place.  Plug it into factory connectors, connect high current power and grounds with pre-terminated terminals to the engine and fusebox (it’s easy), and you’re up and running.
  • Let’s be honest… the harness is just dead sexy.  And you can tuck it if seeing that sexiness is just too much to handle.  We understand.  😉
  • Use with the MSPNP Pro, the MSPNP2, the stock ECU, or even someone else’s ECU.  It just works.
  • Allows you to convert to Sequential Ignition if your ECU supports it!  (MSPNP Gen2 and Pro models do!)
  • Supports stock 12v power, or 16v aftermarket power common in some racecars!
  • Fits VVT cars, Fits RHD cars, clears all known strut tower braces including three point bars.

Only logged in customers who have purchased this product may write a review.

Where is this product assembled?

  • This product is assembled in Suwanee, Georgia, USA

I have swapped a different year engine, will this still work?

  • You must use the MSPNP that matches the year of the engine harness you are using.

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

  • 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.

Will this control VVT if I swap in a later VVT Miata engine?

  • This unit does not support VVT. We recommend starting with an MSPNP Pro if you have or are planning a VVT swap. If you already have this ECU, you could add our VVTuner piggyback device.

What is the difference between the MSPNP Gen 2 and the MSPNP Pro?

  • The MSPNP Gen 2 will provide fuel and ignition control, plus some basic race features such as launch control and boost control. The MSPNP Pro adds a number of advanced features, such as:
    • Programmable alternator voltage control that you can adjust through TunerStudio
    • VVT control for ’01-’05 engine swaps
    • Sequential spark control for coil per plug conversions
    • Eight fuel channels to allow for a fifth injector control or staged sequential injection
    • Boost by gear or ground speed
    • Timed boost delay and spark retard activated by launch control
    • Traction control
    • Rally style anti-lag
    • Advanced flex fuel support that allows blending almost all fuel and ignition tables based on fuel composition
    • Progressive nitrous control
    • Variable water injection control
