Taking it to the MAX?  Two great things that go great together on this Miata/MX5
MSPNP Pro 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!
  • 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?

  • This is a complete package, including USB adapter. But there are some accessories you may want to use to get the most out of this unit.

Do I need to swap to a GM style intake air temperature to remove the mass air flow sensor?

  • No, we use the stock IAT sensor on the Mazdaspeed application.

Questions & Answers

    you have probably been asked this countless time before, but...... the MSM0405 unit is touted as true plug & play. I've almost made all my MSM problems go away, except one thing. The stock ECU must die. For a totally stock miata set up, is you ecu pre-loaded unit fully capable of handling all my stock needs without tinkering. If not, my biggest hurdle is finding a miata savvy tuner/dyno in Florida because nothing is realistically available in the tampa bay area

    Asked by stephen

    This ECU comes loaded with a map for a stock Mazdaspeed Miata, and installation is very simple - click here for full directions. The included map will start the engine if it is on the original injectors and able to run on the stock ECU. For tuning in your area, I recommend talking to Jordan at PowerSquirt Industries - you can contact him through the PowerSquirt website or his Facebook page.

  2. I have a 2004 Mazda 3 sedan 2.3L Gt 4 speed automatic transmission. Does this ecu fit my car?

    Asked by Taylor Kendrick

    Sorry, the Mazda 3 used a completely different ECU design with a different connector. This unit will not fit your application.
