  • Features

    Orion2 Features

    Note that these are all the current features covered by the Orion2. There are some on the charts that is in the process to be developed in the future. The hardware has the capability for it. Also note that not all of the features may be included on the same unit as there are a limited amount of drivers available. Some of the hardware classes may not include certain features due to the price range. See the selection chart for the ability of the different classes.

    Fuel Delivery

    • Accurate fueling such as Batch, Split Batch, Split Sequential and Full Sequential injection gives better performance and fuel consumption due to constant atomization on each cylinder.
    • Fueling is done in graph or matrix method for the tuners preference.
    • All graphs or matrix data are interpolated to smooth fuel calculation accuracy for best performance though the operating ranges.
    • Fuel is calculated with MAP sensor or TPS sensor versus RPM signals or a combination of the 2. This will accommodate most engines ranging from street to racing and from economy to performance.
    • Other sensors that are used to alter the fuel mixture are Water, Air, Altitude, Lambda, Fuel Pressure, Battery Volts and throttle response.
    • Fuel injection timing is adjustable on gear type crank angle sensors as low as 12 pulses per revolution.
    • Adjustable MAP sensor reading angle on gear type crank angle sensors for multiple throttle body systems.

    Ignition Spark & Timing

    • The ECU can do Single, Wasted Spark Coil pack and Coil On Plug (COP) Full Sequential Spark Systems
    • It use the standard coil packs on the engine.
    • Can be connected to most coils with or without internal drivers directly. No pull-up resistor required.
    • Very accurate ignition timing especially with the gear type triggers.
    • Timing is calculated with MAP sensor or TPS sensor versus RPM signals or a combination of the 2. This will accommodate most engines ranging from street to racing.
    • Other sensors that is used to alter the Ignition Timing is Water, Air and Altitude.
    • Battery Volts is used to compensate for coil charge time.


    • The ECU use most standard sensors on the engine No need to do modifications on distributors or converter boards.
    • Custom Bolt-On Timing Gears may be used for older engines that run carburetors or engines with incorrect setups. Gear type triggers do make timing more accurate and responsive during blip conditions. This is the preferred method for racing applications.
    • Sensors can be calibrated to accommodate the different types found on the engines.

    Idle Control & Cold Start – This functions will ease with starting a cold engine and keep the RPMs constant when air conditioners or automatic transmissions draw power from the engine. Idle control is included on board for one and two wire idle valves. The Spitronics stepper control units can be connected to control quad and bipolar stepper motors.

    Launch Control – This feature will increase boost pressure during pull-off to eliminate Turbo Lag. Various methods are available to activate launch like buttons clutch switches TPS position etc.

    Launch Delay Recover – This feature will restore full power with an increasing ramp delay which will help the vehicle with traction control during launch.

    Dual Injectors – The Orion2 has positive drivers that can be used to activate duel injectors with the help of the electronic relay from Spitronics. Fuel can be added bay Ratio which is always available and then also by another fuel graph that is available for 4 cylinder engines.

    Anti-Lag – During deceleration this feature will retain boost pressure to be readily available for accelerating again. It uses the same principle as Launch control except it also has an output to activate a bypass valve for the task.

    Rapid Fire – This feature will make a bang-bang sound in the exhaust for excitement during the launch features. The frequency is adjustable for different sound effects.

    Flat-Shift – This feature will momentarily cut spark to allow faster shifting of gears.

    Dual Maps – This ECU can be tuned for 2 different fuel and performance setups. Ideal for the weekend racing enthusiast. On TCU there is 4 maps available.

    Map Change on the fly – This feature will allow the driver to change to a different map during driving.

    General Purpose Outputs – This can be used for injectors, fan control, shift light, Aircon Cut-Out on Pull-Off or Up-Hill etc. The amount of GP outputs varies between firmware and features activated on the device. All drivers that is not used by the firmware will be available as General Purpose Outputs.

    Connection Layout Print – This feature will allow the dealer to print a layout of the connections of the Orion2 after he set it up in software. It will help new customers to finish their wiring with less time.

    Standard Harness – No need to keep several harnesses in stock for different engines. There are however custom harnesses for certain engines that will ease installation time. All the input wiring harnesses use screened cables for neatness of installation and to prevent electromagnetic interference which may cause erratic behavior of the ECU. On the TCU we have slight variations in the Add-On boards to accommodate the different transmissions.

    Internal 3Bar Map Sensor – This optional sensor can be added to use as Altitude sensor or internal Map sensor. It may save cost and time to do connections to an external map sensor.

    Compact Electronics – This will make the Orion2 easy to install under the dashboard as it takes very little space. It is also very suitable for Motor Cycles and boats.
