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 a 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.

• 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?

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
