It can drive basic coils, smart coils, injectors, solenoids, throttle by wire motors etc. directly. Due to the versatility some devices may require external resistors or diodes which is supplied with the Orion2. It can read signals from sensors like water & air temperature, throttle position, manifold pressure, crank angles, cam angles, lambda, fuel pressure etc. directly.
The Hyperspace tuning software is user-friendly and makes all the above features customizable by the tuner. This makes the Orion2 adaptable for most applications on site.
To learn more about this amazing package browse through the features and specifications in the sub folders.

Note that some features are 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 ECU as there is 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 fuel amount and injection timing gives better performance and fuel consumption due to constant atomization on each cylinder.
  • Injection methods such as Batch, Split Batch, Split Sequential and Full Sequential are offered with the Orion2. Full Sequential can only be done for 4 Cylinder.
  • Different Tuning options such as graph or matrix can be selected.
  • All graphs or matrix data are interpolated to smooth fuel calculation accuracy for the best performance though the operating ranges.
  • Fuel is calculated with MAP or TPS sensor signals versus RPM or a combination of the two. 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, Battery Volts and throttle response from the driver.
  • Fuel injection timing is adjustable on gear type crank angle sensors as low as 12 pulses per revolution. This will result in a 30° angle resolution or smaller.
  • Adjustable MAP sensor, reading angle for multiple throttle body systems.
  • Dual injectors can be used in two methods. Staged injectors namely Ratio adjust or Graph Fazed method.
  • Injector trimming up to 4 injectors can be used for Full Sequential Injection. Full Sequential can only be done for 4 Cylinder.
  • Fuel enrichment can be adjusted during Launch, RapidFire or retard functions.


Ignition Spark & Timing

  • The Orion2 can manage Distributors, Wasted Spark coil packs, Wasted Spark COP coils or Full Sequential spark systems. Full Sequential can only be done for 4 Cylinder.
  • Orion2 uses standard automotive coil packs found on engines. No need to change them.
  • Most Smart Coils with built in drivers and Basic Coils without drivers can be connected directly. Orion2 has up to 6 HV coil drivers built in.
  • Orion2 can also use the Mercury Coil drivers to free up internal drivers. Coil drivers can be stacked to accommodate V8 systems and V8 Dual Coil engines. The latter have 16 coils.
  • Orion2 has very accurate ignition timing especially with the gear type triggers.
  • Timing is calculated with MAP or TPS sensor signals versus RPM or a combination of the two. 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.



  • Orion2 can 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 RPM’s 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. It can also do delayed launch recovery to improve traction.


Anti-Lag Control – This feature will increase boost pressure during racing to eliminate Turbo Lag on corners. Newer firmware has an output option to activate EGR valves to bypass turbo pressure to the exhaust. This will help with engine braking in corners and to keep boost pressure high for accelerating out of the corner.


Flat-shift Control – This feature will momentarily cut engine power during wide open throttle to assist in manual gear shifting.


RapidFire – This launch feature will make a machine gun sound in the exhaust which is desired by the drifting crowd. The frequency is adjustable and the amount of flames displayed at the outlet.


General Purpose Outputs – Up to 10 GP drivers can be used if there are enough available. They can be used for injectors, fan control, shift light, Aircon Cut-Out on Pull-Off or Up-Hill etc.


Standard Harness – No need to keep several harnesses in stock for different engines. Level 2 harnesses will include relays and fuses that will ease installation and save 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.


Compact Electronics – This will make the ECU easy to install under the dashboard as it takes very little space.


Complete Firmware for Most Engines.


Cost Effective – No need to buy expensive systems as all the necessary features are included with the ECU.


Rotary Systems – The 2 rotor engines are covered by this Orion2.


External Map Sensor – Easy to change between 1Bar, 2.5Bar, 3Bar 4Bar & custom configurations. External sensors are used to reduce the delay in the vacuum signal It makes the ECU more versatile to adapt to standard MAP sensors found on engines.


Altitude Compensation – This feature is important as the ECU will automatically compensate for differences in pressure.


Standard Tuning Software – All the products use the same software. The features that is not used or allowed in the firmware will be blanked out.


Easy DIY Instructions – Save money on installation if you are a person who is up to the challenge.


Start-Up Maps included – This will make for easy start-up & tuning with the help of a Lambda sensor.


User Friendly Tuning Software which is extensively explained in the manual.
