Orion2 Overview
This versatile Automotive Controller is designed to be a low cost durable effective replacement for high tech Vehicle Electronic Units. It can be used on most engines, transmissions and other products in the motor vehicle industry. It uses unique and easy features which are easy to install and tune. It is designed with the novice and professional installer in mind.
This universal South African made product can easily be customized for various engines, transmissions etc. It can be used for many applications such as racing engines, vehicle conversions, custom built vehicles, replacement parts for production vehicles etc. It is a compact reliable system which can be epoxy filled to make it rugged and water tight for harsh environments and is easy to mount in the driver’s compartment.
The Orion2 can be reprogrammed remotely by a software bootloader. No need for expensive equipment like programmers or separate cables. This will allow a dealer to have less inventory on his floor and customize this product on demand. This product is also sold in different classes which makes it more viable to use for smaller applications. It may also be bought at reduced prices in un-activated status. This will allow the dealer to have better control over his cash flow management in his business. Activations of features can be done over the internet making the unit viable to keep in stock at dealers. Activation will then require the rest of the unpaid amount.
The Orion2 unit is designed to connect directly to most sensors and drive units that is found on engines, transmissions and other products. No need to modify them. It consists of the latest in high speed micro controllers with surface mount technology. These units are machine soldered to minimize human error.
The Orion2 cover features like Lambda control, idle control, launch control, Anti-Lag Control, Flat Shift control, Rapid Fire Exhaust Control, cam control, stepper motor control, throttle by wire control, boost control, line pressure control, tiptronic and lots more. 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.

Tiptronic or Paddle shift
· Automatic Mode – the driver sets the maximum target gear allowed.
· Semi-Automatic Mode – the driver has more manipulation of the gears with the added automatic features.
· Manual Mode – the driver has complete control over the transmission with the added protection against over revving.

Tune or Map Selection Switch – lets the driver set up his transmission in 4 different profiles like Automatic, Tiptronic, Towing, Off-road, Racing etc.

Shifter Position input
· The TCU can sense all kinds of shifter sensors to operate correctly in all lever positions. Different sensing boards could be connected to sense serial or parallel switches. Also switches with common Positive or Negative could be connected with the Level Shifter board.
· If no shifter sensor is available then the reverse light signal can be used to lockout shifting in reverse.

Gear Profile Adjustments – Each gear can be separately manipulated to shift up or down when the tuner requires it. These settings work on RPM, Speed and TPS values.

Line Pressure Adjustments – These pressures can be adjusted on a graph with the TPS representing engine load. There may be a number of graphs according to the transmission requirement. The software cater for 3 different graphs.

· TPS sensor will indicate to the TCU what the driver’s intention is. Shifting can be adjusted accordingly.
· RPM signal will be used to shift the transmission to harness the engine power correctly and be economical.
· Speed sensor will be used as protection against down gear over revving and also other shift algorithms.
· Transmission Oil Temperature sensor will change line pressures during cold conditions to soften gear shifts.
· Low range sensor will adjust speed settings in the transmission automatically.
· Shifter Sensor indicates which position the lever is selected. this will indicate the TCU which gear selections are allowed.
· Tune Map Sensor will adjust shifting behavior according to selections by the driver.
· Sensors can be calibrated to suit most engines and transmissions.

· Shift solenoids will manipulate the required gear to be selected
· Duty control solenoids will control line, lockup and shift control solenoids to make the transmission as comfortable to the driver as possible.

General Purpose outputs – These outputs can be used for custom features like speed warning, sirens etc.

Speedo output – this signal drives speedometers and can be calibrated in the software.

Selectable Lockup – can switch on in all gears if transmission permits to improve economy and reduce heat.

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 TCU. There are a few add-on boards to ease between different transmission wiring options.

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

Complete firmware for Most transmissions.

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

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.

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

Tuning map – can be locked to prevent tampering. Useful for transmissions builders to give guarantees.

No Dyno Required – Tune your own transmissions and save some money. Just follow the instructions in the manual carefully.

(Note that the last five points are for the person who is handy with tools and understand wiring and operation of transmissions. If you are not sure, download the software, Map, manual and drawing and experiment with it first. It’s free of charge!)
