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.

Yes. VVT control is standard equipment on 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
