This is a Plug and Play Standalone ECU for the popular Honda OBD1 92-00 Civic/Integra/Del Sol B, D and H series engines. This hardware is purpose built using components from this decade, so you can ditch the 1990's era ecus! The ECU Runs RusEFI Firmware and uses Tuner Studio for Tuning.

This new hardware allows for a more responsive and accurate tune, much faster download speeds and overall greater datalogging. The BoostedNW Standalone enables skilled tuners to finely tune parameters for peak performance in modified vehicles, enhancing drivability and power output efficiently.

Each BoostedNW Standalone ECU includes a base map, intended to streamline the tuning process for both you and your tuner. However, it's crucial to view these maps as initial guidelines, serving merely as a foundation for further customization and refinement during tuning.

This innovative Honda plug-in ECU offers significant time and cost savings by seamlessly integrating into the vehicle's original wiring harness, eliminating the necessity for cumbersome adapter harnesses (unless your vehicle is obd0/obd2)(OBD2 cars will need obd2 to obd1 conversion harness - see add on option). By effectively replacing the conventional circuit board housed within the factory ECU enclosure, this advanced plug-in unit simplifies installation and enhances compatibility, ensuring a hassle-free upgrade experience. Furthermore, its seamless integration allows for straightforward mounting using the existing factory brackets, facilitating a streamlined and efficient installation process. Thus, by leveraging cutting-edge technology and precision engineering, this plug-in ECU presents an optimal solution for enhancing vehicle performance while minimizing installation complexities and associated costs.

This ECU board was made to fit inside a obd2 large case ( We Provide in a Powder Coated obd2 case, fits right in place of any obd1 or obd2 ecu) and uses the standard OBD1 3 plugs + extra ( so it looks like obd2 but its not, it just has the extra smaller plug, so there is 4 total). The extra plug is used for WB02 inputs, flex fuel and other future possible inputs. It has a VR conditioner specifically designed for the OEM Distributor and modification is not required.

ECU Features:

    • Built in Coil on plug ready
    • Built in 4.9 LSU Wideband Controller (comes with cable for "extra" smallest honda plug prewired with wideband connector on other end, just direct plug to a 4.9 LSU sensor!) ( Can add on a Genuine Bosch LSU 4.9 Sensor as option before adding to cart)
    • Built in SD microSD card slot for datalogs
    • Built in Bluetooth connectivity to aftermarket dash or Android Phone/Tablet or Laptop
    • Up to two CAN buses
    • Built in Flex fuel input (no converter needed, just feed in flex fuel sensor wire) (can add pin to same "extra" connector provided above for wideband, so there are no extra wires coming from anywhere on ecu except ecu plugs).
    • Built in Knock sensor input
    • USB Type C Direct connection to PC
    • Stock ECU case so goes right in stock ecu location
    • Switched Dual Maps
    • Launch Control/Flat Foot Shifting
    • Closed Loop Boost Control/Boost by Gear
    • Water Methanol Injection
    • MAP sensor – The factory MAP sensor is supported. This is suitable for up to 175kpa (11psi) boost. If more boost is intended to be used a higher rated sensor can be connected to the existing wires or you can use optional on board map sensor(see next line).
    • Optional Onboard 2.5 or 4 bar map sensor, instead of using stock honda map sensor.
    • Inlet Air Temp Sensor (IAT) -The factory IAT sensor is supported. To avoid issues of heat soak an alternative IAT sensor can be fitted just prior to the throttle body & connected to the existing IAT wires.
    • Comes with Full Product support around Basic use issues, this does not include teaching you how to tune. Any tuner will know fully how to use this hardware and the software that is used to tune.
    • Comes with full 1 year product hardware warranty.(warranty does not cover fried components due to improper hookup; ASK Questions before you just try something, and fry something!)

NOTE: Don't worry, after in-stock units are sold out, pre order units have less than a 2 week wait! Next batch is already in the works/on the way.

This is not a "Speedduino/pnp duino/honduino" or other ecu that uses cheap consumer grade/hobby $20 off the shelf arduino boards to control ecu functions. This is a purpose built ECU with STM32 Microprocessor and many other newer components, and fully protected inputs and outputs, making for a very up-to-date and feature rich ECU! This ECU is intended for off road/RACE use only.



Some Software KEY Features:

Amazing Dashboards - Perfect for setting up a dedicated car PC or giving your laptop head snapping wow factor, TunerStudio MS brings you:



    • Tabbed Dashboards - Add as many dashboards as you wish allowing yout to quickly change views depending on what you may be working on or to provide different look in a snap.
    • Gauge Styles - A growing list of available Gauge styles gives you the power to create dashboard designs limited only by your imagination. Additional Gauge Styles can requested any time you think of one.
    • Full Screen Dashboards - With a simple double click or selecting from the menu you can make any tabbed dash go full screen. You can even set it up to go straight to full screen on startup.
    • Dashboard Designer - Modify any dash in a snap or build your own from the ground up with designer mode. Designer mode gives you a full WYSIWYG drag and drop interface allowing you to place gauges anywhere you like. You select the styles, limits, fonts, colors, titles and text. You can save and share your work or just show it off.


VE Analyze Live! - Tune For You - Yes it really does tune the car for you while you drive! Starting with concepts of VE Analyze in MegaLogViewer 2.95 and taking it to the next level with dynamic offset record seeking. Whether your just running with rough tables or have already put hours into your tune, VE Analyze Live will dial in your fuel tables to a new state. Why does it work so well? By combining a vast tuning experience with expertise in data analytics you can leverage technology to improve your tune. An expert tuner can look at a data log record and know what changes that record is looking for, but one record can only tell so much. At best a record only shows the inputs and results at that instant in time with many other outside factors effecting the data. One record nay tell you one thing, but another on the same cell will say something else. To produce the best results you need to look at each record, identify and discard the ones that are junk due to other factors, then consider ALL quality data. That is where the human brain fails, it simply can not consider the full picture, computers can. As you drive VE Analyze live will look at all the data, filter what the junk and use weighted statistical averages to calculate the optimal values for you Fuel tables.



VE Analyze Live offers:

    • Automatic update to controller - You can either have TunerStudio produce a recommended table as you drive, or let it acutally send the updates as you drive to continually improve you tune while going down the road.
    • Adjustable Standard Filter - In addition to TunerStudio filtering data with lack of credibility, you can adjust standard parameters such as RPM, Coolant temp, load, MAP, MAF to match your configuration or preference.
    • Custom Filters - One of the Standard Filters doesn't cut it for your setup? The custom filter lets you apply free form logical and mathematical formulas to filter nearly any data you desire.
    • Lambda Delay Table - Compensates for delays to your Lambda Sensor readings caused by not just the Lambda sensor itself, but more importantly the time spent flowing through the exhaust pipes under varying conditions.
    • Heat Maps - As you drive you can see how much data has been gathered for all sections of the table and how much the table values have changed.
    • Authority Limits - Allow you to limit the amount of change TunerStudio can make in a single session to prevent damage if something goes wrong.
    • Full Readouts - Watch the major data elements as TunerStudio uses them with a gauge cluster and histogram to show just what your engine is doing.



Additional Tuning Aids - Throughout the Full Edition of TunerStudioMS you will find additional features and settings to make life simpler while tuning.

    • Adjustable 2D table tell tail - Blue line and dots to show the path through the map you have taken. The number of records is configurable.
    • Improved 3D Tables - Configurable increment sizes, accented value changes, more user settings.
    • Switchable 2D to 3D View - Snap nearly any table to 3D view mode to gain quick insite with a different perspective.
    • Plus more - This list continues to grow with active development rapidly continuing!
