Enhance your Mazda Miata with the AMP Plug-N-Play ECU (AMP PNP) – the next evolution of the proven MSPNP-Pro platform, built on the same trusted MS3Pro Technology used in high-performance motorsports applications worldwide. The AMP PNP delivers the same rock-solid reliability, advanced tuning capability, and proven performance customers have trusted for years — with major usability and hardware upgrades that make installation cleaner, expandability easier, and tuning more powerful than ever. This is not a new, untested system — it is a refined and enhanced version of the MSPNP-Pro, redesigned to give you more capability with less complexity.
Integrated Wideband O2 – No External Controller Required
The AMP PNP is now available with an optional fully integrated wideband controller, eliminating the need for external modules and extra wiring.
- Uses the same Bosch-based wideband control technology as our proven standalone wideband
- Powered by Bosch IC chips and Bosch LSU 4.9 sensor compatibility
- No separate wideband controller required
- Simply plug the included wideband sensor cable directly into the ECU
Benefits:
- Cleaner installation (no extra boxes or wiring)
- Faster setup and reduced install time
- Improved reliability with fewer connection points
- Seamless integration with ECU tuning and datalogging
This brings professional-grade wideband control directly inside the ECU, simplifying your setup without sacrificing performance.
Features:
- Fully Plug and Play Installation – No wiring required for basic functionality.
- Average install time is under 1 hour!
- Base map is pre-loaded to help your engine start on the first turn of the key
- Real time tuning and data logging with a laptop connection
- 8 GB internal data logging with built in SD card
- Supports most aftermarket wideband sensors
Completely configurable, live tuning:
- 16×16 Fuel Tables allow high resolution tuning
- 16×16 Ignition Tables
- Multiple Acceleration enrichment strategies
- Closed Loop Idle Speed Control
- Air Conditioner Control
- Up to 4 sequential fuel injector channels with individual trim tables (minor wiring change required if you want to enable sequential injection, as most of these cars were not wired for sequential injection from the factory)
- Onboard high impedance injector drivers
- Allows removal of stock airflow meter
- Allows adding a variable TPS – no special mods needed!
Advanced Feature Set (included as standard features on PRO)
- 12×12 Air Fuel Ratio Target Tables for use with wide band O2 sensor for precise tuning and table trim.
- Built-in 2-step rev limiter / launch control with flat shift

- Input for flex fuel sensor – switch between E85 and gasoline on the fly!
- CANBus connector allows interconnection of other MegaSquirt-compatible devices for additional functions (EGT Input, Automatic Transmission Controller, Additional Sensors…..the possibilities are limitless!
VVT CONTROL
The MS3Pro comes equipped with full closed loop VVT control. This can be VERY useful if you plan to retrofit a 2001+ VVT engine into a an earlier model chassis, as you can simply use one of the spare outputs to drive the VVT solenoid, as well as keep the later crank/cam sensors.

The best option
After attempting to buy a beer money motorsports ECU & waiting 3 months; I decided to get a refund. The only other option I considered was this PNP unit. It arrived quickly (a week or less). Super nice quality & packaging. Fab9 is a pleasure to deal with, cheers guys.
