New second generation MSPNP!

We've totally redesigned the MSPNP! This new second generation unit runs MS2/Extra sequential code, using the MicroSquirt Module and a lot of new MSPNP-specific hardware. We've added several major improvements over the original. Here's the features of the new model.

Easy to Use and Install!    

    • Fully Plug and Play Installation - No wiring required for basic functionality.  Average install time is under 1 hour!

    • 4AGE base map is pre-loaded to help your engine start on the first turn of the key (other model base maps included on CD)

    • Real time tuning and data logging with a laptop connection

    • Supports most aftermarket wideband sensors

Fully Tunable Engine Control!     

    • 16x16 Fuel Tables allow high resolution tuning

    • 12x12 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 to run sequential, 4AGE only)

    • Onboard peak and hold drivers support both high and low impedance injectors - No external ballast resistor is needed!

    • Allows removal of stock airflow meter

Advanced Feature Set (Included!)

    • 12x12 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

    • Real time barometric correction

    • Internal 4-bar MAP sensor reads up to 44PSI of boost

    • Overboost protection

    • Closed loop boost control (Requires DIYAutoTune.com EBC solenoid kit)

    • Knock sensor input with adjustable sensitivity

    • Headphone output for knock sensor - listen for knock while you tune!

    • Table switching input. Change fuel and spark maps on the fly for different fuels, nitrous activation, etc.

    • 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!


What you get in the box:

    • MegaSquirtPNP T8590 ECU

    • MSPNP RS232 serial tuning cable, 6' (USB adapter sold separately, if needed)

    • Tuning Software and Documentation CD

    • 6' Vacuum Hose for MAP Signal and 'T' fitting

    • Four Screws for ECU mounting

Note that although there is a paid upgrade to TunerStudio, it is not needed to tune this ECU. The free version included on the CD can access all the features and tables of the MegaSquirtPNP. The paid version of TunerStudio simply adds tuning and analysis software, such as VE Analyzer Live to tune the fuel tables based on wideband O2 feedback (requiring a wideband O2 sensor and controller, sold separately).
