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?

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

  • Yes. VVT control is standard equipment on the MSPNP Pro.

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
