This block indicates the type of coil combinations that can be used with this firmware. Some firmware programs will allow the user to select between the different coil combinations on his engine. Note: If you have an intermediate or lower hardware class ECU, you may only use single coil with […]
Active Sensors
This block lets the tuner select the different sensors that he requires for his application. Not all the sensors are used but each one has different features that makes the engine perform at its best. If a sensor is not used, leave the block unchecked. This will free up valuable […]
Lambda Loop Control Tuning
All Spitronics ECU’s have the capability to do loop control with a lambda sensor connected. The tuner may set up parameters for lambda control and then the ECU will compensate the main air fuel ratio according to the lambda sensor in real time. This will result in the optimum mixture […]
ECU Setup
General Settings or Timing Settings Injection Settings Sensor Settings Turbo Settings This blocks are where all the setup values for the ECU are grouped so that the tuner can setup his engine.
Timing Calculation
This block will allow the tuner to choose different options to set up timing for this engine. Each of these methods will be discussed in detail under the tuning chapter further in the manual. You can see the Tuning section for detailed description on the tuning side. Graph MAP This […]
Crank and Cam angle Sensors
These inputs are required by the ECU to determine exact crank and cams angles so that spark and injection timing can be calculated. Crank (TDC) The crank angle sensor is used by the ECU to determine exact crank degrees as it rotates. This sensor could be situated on the crank […]
Timing Configuration
Maximum trailing This is for rotary engines and prevents the trailing degrees from being adjusted to far from the leading plugs. In piston engines this block is hidden. Maximum Timing This is the maximum combined timing allowed in degrees by all the timing maps combined. If the graphs are tuned […]
Engine Configuration
Engine Type The ECU firmware will lock this selection for a Piston or Rotary engine. For Rotary it will enable a Trailing degree graph and also a Maximum trailing degree setting. For most firmware this block will be hidden. Cylinders Most ECU firmware will lock this selection for a specific […]
Idle Control
The ECU has the feature to control different types of idle motors found on an engine. Before adjusting the idle control settings, you need to select which type of valve or stepper is on the engine. Note: The stepper types idle motor (4 to 6 wire), require the external electronic […]
RPM Output
Pulses/RPM This feature is used for Rev counter calibration. You can adjust the number of pulses per revolution for the RPM output. This is handy for engine conversions. A value of 1 to 60 pulses can be achieved with this function. On some firmware you may enter 61 which will […]
