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?

  • On ’01-’05 Miatas, the IAT sensor is separate from the mass air flow sensor, so it is not necessary to get a GM type sensor if removing the MAF. However, if you are relocating the IAT sensor for a turbo installation, it is often easier to use a threaded IAT sensor such as the GM design.

    This is a race ECU. It completely ignores the anti-theft system. While this would not be appropriate for a daily driver since it also completely ignores the smog equipment, it would be a good way to build a track car out of a car with electrical damage.

    Yes. On current versions, the pins are marked for connecting a USB port to the header.

    The pinouts between the regular and Mazdaspeed versions of the Miata are very similar for 2004-2005. Converting between the two is a matter of changing internal jumpers inside the ECU and loading the appropriate tune file.

    This unit uses High Current Out 1 (under Advanced Engine -> Prog. On/Off Outputs) for the primary cooling fan output and Injector Out I (under Basic Settings -> Fan Control) for the secondary / condenser fan. It's already wired for both.
