The motherboard house the Micro Processor and most of the machine soldered surface mount components. These are components that are difficult to solder by hand. All the other components are hand soldered and left for the customer to do himself. The motherboard is tested and serialized on the system.
The customer also has a selection of components to choose from. He may decide in better quality components or cheaper solution components. You don’t always require the best expensive drivers specially for Injectors. Some of the parts may not be required for his build then they don’t have to be soldered onto the board. This will save money and time.
Once a board is built it still requires activation credits for all the different features before it will function correctly. This however is done over the internet and does not affect the customer’s prices. See the activation credits chart for features and pricing. Some of the features may not be required which will save the customer on money again.
The Eezi4 ECU was designed as a small compact unit for 4-cylinder engines. However, it is also suited for certain larger engines where the number of outputs is adequate for the task. The Firmware and Tuning Software will make the most of your selections and offer the maximum quantity of features possible with the available drivers. See the selection chart of possibilities for different applications. Note that features will be installed by activation credits loaded on the Eezi4. See activations section. Features covered in this DIY product are the following:
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’ preferences.
- 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 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.
- 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 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.
Sensors
- 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 function 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 Eezi4 has positive drivers that can be used to activate fuel injectors with the help of the electronic relay from Spitronics. Fuel can be added by 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.
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 Eezi4 after he set it up in software. It will help new customers to finish their wiring with less time.
Harness – Build your own harness with the correct number of wires and save money. There is complete documentation to build them to our standards. You may also use some of the Spitronics product harnesses. See the Harness section for more information.
Internal 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. It comes in 1.1Bar, 3Bar and 4Bar types.
Compact Electronics – This will make the Eezi4 easy to install under the dashboard as it takes very little space. It is also very suitable for Motor Cycles and boats.
Cost Effective – No need to buy expensive systems as all the necessary features are included with the Eezi4. More development will add more features later.
Rotary Systems – The 2 rotor engines are covered by the Eezi4.
Dynamic Injection Angle – This feature is for Rotary engines where the injection angle is adjusted during rpm change. It has 2 graphs for 360° for Primary and Secondary injectors to adjust separately.
External Map Sensor is easy to change between 1Bar, 2.5Bar, 3Bar & 4Bar types. External sensors can be used to reduce the delay in the vacuum signal. It makes the ECU more versatile to adapt to standard MAP sensors found on engines. OEM map sensors can be used and calibrated under the Custom selection.
Altitude Compensation – This feature is important as the ECU will automatically compensate for differences in pressure. The Sensor can be the internal or the external sensor.
Critical Settings Warning – With Eezi4 all the settings that may change wiring connections are now protected by a warning so that the tuner may not accidently change the setup of the device.
Standard Tuning Software – All firmware use the same software. The features that are not used or allowed in the tuning software will be blanked out.
Easy DIY Instructions – Save a lot of 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 documentation.
Tuning map can be locked to prevent tampering. Useful for engine builders who give guarantees.
No Dyno Required – Tune your own vehicle and save some more money. Just following the instructions in the manual carefully with the use of the Hyperspace Data logger.
(Note that the last four points are for the person who is handy with tools and understand wiring and operation of an engine. If you are not sure, download the software, Map, manual and drawing and experiment with it first. It’s free of charge!)
