Getting Started When you start the Stinger 4 ECU Control Software the first screen to appear is the tuning screen.
You can read data from the ECU or a saved file by selecting the appropriate menu option.
You can also read tune files created with version 3 software.
To read from a saved file you go to menu option "File - Open Tune File", select the file you want and press the "OPEN" button.
To read from an ECU you must first have one connected and on-Line. You can tell if an ECU is on line when the green light on the bottom right corner of the window is flashing.
To bring a connected ECU on-line go to menu option "ECU - On Line". If the command is successful then the green light will be flashing.
To read from the ECU go to menu option "ECU - Read from ECU". If the ECU is connected and On Line then the information will start down loading into the PC/Laptop.
All ECU data is saved in files. You can create any number of files each with a different name. To save the data to a file go to menu option "File - Save Tune File", enter a file name and press the "SAVE" button.
See Convert Stinger 3 files to Stinger 4 Setting the ECU parameters for a specific engine Press the Goto "ECU Setup" button to go to the ECU Setup screen. Use this screen to set the parameters for a specific engine. You can set parameters such as number of cylinders, number of igniters, types of engine sensors attached, load sensor type etc.
See ECU Setup Screen Auxiliaries There are 2 parts to the Auxiliary Control Settings screen.
Output Control Circuits and Input Control circuits See Digital Input See Turbo Anti Lag Output Control circuits The Stinger 4 provides four programmable auxiliary outputs, each output can perform one of 12 functions. 8 of the 12 functions can be used to control relays and tachos, the remaining 4 provide pulse width modulated output for controlling variable devices such as PWM idle control motors and boost control.
Use the Auxiliary Output screen to define the function for each output.
See Auxiliary Outputs See PWM modes 9 - 12 Engine Tuning The Stinger 4 control software provides a graphical view of the ECU mappings.
This gives the user an instant overall picture of how an engine is tuned, highlighting any abnormalities.
All engine tuning is performed via this screen.
If the Ecu is on line with this computer, any change made to the tuning maps is instantly transmitted to the ECU.
See Fuel and Ignition Maps Tune Analyser Tune Analyser is a feature designed by EMS to assist in tuning an engine to its peak performance See Tune Analyser Data Logging The Stinger 4 system provides flexible data logging capabilities to assist in gaining the maximum efficiency from an engine.
NOTE: Data logging is only available if the ECU is attached for data logging.

Steps to open version 3 tune files.
1 Select the "Open Tune Files" option and then select "Stinger 3 Tune Files" in the "File of Type" field. (This will show all Stinger 3 tune files).
2 Select the file you want to convert and press the "Open" button.
3 Save the file. Once saved, the file will be converted to version 4.
All version 2 files must be converted to version 3 first.
Steps to convert version 2 tune files.
1 Open a tune file using the version 2 software 2 Download this tune into a Stinger 3 or Stinger 4 ECU that has not been upgraded. (Serial numbers beginning with ST1, ST2, ST3 or ST43) 3 Close the version 2 software and open the version 3 software 4 Read the tune back from the ECU you just down loaded into the version 3 software.
5 Save this file.
6 Close the version 3 software and open the new version 4 software.
7 Select the "Open Tune Files" option and then select "Stinger 3 Tune Files" in the "File of Type" field. (This will show all Stinger 3 tune files).
8 Select the file you just saved using the version 3 software and press the "Open" button.
9 Save the file. Once saved, the file will be converted to version 4.
If a version 3 file has been opened with the version 4 software then you will need to reset the soft and hard rev limiter values as well as the boost cut value.

Load source 1 is the main default load source that the ecu uses in the Fuel and ignition main MAPS. This can either be MAP sensor or TPS Injector Arrangement Multi point 360 for rotary and piston engines Check the position of the fuel injectors. They must be fitted as Multi Point (1 injector per cylinder).
When Multi-point 360 is selected regardless of the number of cylinders, the computer will fire the injectors twice every cycle (once per crank rotation).
Throttle body should be selected for 2 strokes.
Multi point 720 for piston engines only Check the position of the fuel injectors. They must be fitted as Multi Point (1 injector per cylinder).
When Multi-point 720 is selected regardless of the number of cylinders, the computer will fire the injectors once every engine cycle (two complete crank revolutions).
Using Multi point 720 will provide smoother idle with larger injectors.
NOTE: Throttle body should be selected for 2 strokes.
Throttle Body for rotary and 2 or 4 cycle piston engines Check the position of the fuel injectors. They may be fitted to a Throttle Body (all injectors at one single point).
When throttle body is selected the computer fires the injectors every ignition pulse if it is a 6cyl or less. If it is a V8 or more the computer will fire the injectors every 2nd ignition pulse.
See Injector connections Injector Connections Trigger Sensor Type General Signals from Optical, Hall or Magnetic sensors can be used to trigger the Ecu on the trigger circuit or the sync circuit. These inputs are programmable by selecting either of the following.
Hall / Optical Hall and Optical sensors are usually 3 wire sensors.
They produce a square wave signal.
see See Trigger and sync sensor connections Magnetic Magnetic sensors are 2 wire sensors.
They produce a sine wave signal.
see See Trigger and sync sensor connections.
Trigger and Sync Sensor Connections Trigger Edge General The trigger edge determines whether the computer is triggered by the positive or negative edge of the trigger signal.
The computer can be triggered by either edge.
For MagneticThe trigger edge must be set to positive.
For Hall / Optical sensors Depending on the sensor Wheel Slots / Teeth, The signal will either be Rising or Falling at approx 10 degrees BTDC.
If unknown, connect a multi meter from the Trigger wire to ground and watch the voltage level change while turning the engine slowly by hand to determine if the signal is Rising or Falling.
If Rising, select + Trigger If Falling, select - Trigger.
Disconnect the ignition coils before rotating the engine by hand.
Trigger Resistor When Hall is selected for the trigger input, the "TRIGG RES" feature gives you the option of selecting "ON" if the ECU is to Introduce a 1000 ohm pull up resistor to 8V or "OFF" if the 1000 ohm resistor is to be disconnected.
TRIG RES "ON” TRIG RES "OFF" The "ON" is usually selected if the Stinger 4 ECU alone is to be connected to the trigger sensor.
If Stinger 4 is installed in a piggy back situation where the original ECU is still connected to the trigger sensor then both computers' will share the signal.
Since the original ECU has a pull up resistor in circuit, the Stinger 4 pull up should be selected to be "OFF".
Magnetic Sensor When a magnetic sensor is selected for the Trigger sensor, the Trigger Resistor is automatically turned off by the Ecu regardless of this setting.
