MS3Pro Plug-N-Play Standalone Engine Management System

With the MS3Pro PNP EMS, we've simply taken all of the wiring homework and labor out of the project for you. Allows you to tune your BMW with a laptop to handle any mods you can throw at the M20, M30 & S38! We provide you with a solid base map to tune from to make your installation and tuning process go incredibly smoothly whether you're a super technical computer-geek or just a gear-head. Now you've got no more excuses... 

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
• 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

Easy to Use and Install!    

• 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

Fully Tunable Engine Control!     

• 16×16 Fuel Tables allow high resolution tuning
• 16×16 Ignition Tables
• Multiple Acceleration enrichment strategies
• Closed Loop Idle Speed Control
• Air Conditioner Control
• 4 sequential fuel injector channels with individual trim tables
• Onboard peak and hold drivers support both high and low impedance injectors– No external ballast resistor is needed!
• Allows removal of stock airflow meter

BMW E30 MS3Pro PnP ECU Advanced Feature Set (Included!)

• 12×12 Air Fuel Ratio Target Tables for use with wide band O2 sensor for precise tuning and table trim.
• Multiple traction control strategies
• Built-in 3-step rev limiter / launch control with flat shift and burnout rev limiter
• Real time barometric correction
• Internal 4-bar MAP sensor reads up to 44PSI of boost
• Overboost protection
• Closed loop boost control (Requires EBC solenoid kit – stock boost control solenoid does not allow adjusting boost level)
• Rally style anti-lag
• Water injection control – on/off or variable
• Knock sensor input with adjustable sensitivity, crank angle windowing, and more
• 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:

• MS3Pro PnP ECU for the BMW E30 / E32 / E34
• MSPNP RS232 serial tuning cable, 6′ (USB adapter sold separately, if needed)
• Tuning Software and Documentation on USB memory stick
• 6′ Vacuum Hose for MAP Signal and ‘T’ fitting
• Four Screws for ECU mounting
• Registered version of TunerStudio and MegaLog viewer included
• 26 pin connector for options port with 6″ wire pigtail
• Make sure to use our Custom TunerStudio Dashboard, designed specifically to help make tuning your new build intuitive and easy!

Fits multiple BMW models:

• 1987-1992 325i (E30 Chassis with M20) *
• 1988-1992 735 (E32 Chassis with M30)
• 1989-1990 525 (E34 Chassis with M20)**
• 1989-1993 535 (E34 chassis with M30)**
• 1991-1993 M5 (E34 chassis with S38)

*This does not fit BMW e30 325e models with the eta engine (except the 1987 “Super Eta”), or the 1992 E36 chassis 325i with the M50 (in 1992, the convertible used the E30 chassis, while coupes and sedans received the new E36 chassis). These used a different ECU design. Additionally, some European 325i models for the 1987 year used an ECU with a part number of 0 261 200 073 or 0 261 200 081; this ECU is not compatible with the stock wiring on these cars.

**Also, this MSPNP may not work with automatic transmissions on the E34 or E32 chassis, which rely on the fuel consumption signal for the transmission computer. Automatic equipped E30s using a hydraulic transmission will work without issue.

Suggested Add-ons:

• If you want the ECU to control boost, you will need a boost solenoid.
• We always recommend purchasing a new IAT sensor.
• We also recommend purchasing a high-quality wideband sensor.
