FAQ
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.

  • If you are tuning it yourself, a wideband O2 sensor system is a must have for adjusting the fuel.

  • This unit can function as a boost controller if you add a boost control solenoid package.

  • If you are removing the mass air flow meter, use our IAT sensor kit to provide the MSPNP with air temperature measurement.

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
