Idle Speed Control
- Supports idle speed control by idle solenoid, idle stepper motor, or electronic throttle.
- Idle speed control has two modes available:
- Open loop mode in which the ECU sets the position of the the idle control device for a given engine coolant temperature.
- Closed loop mode in which the actual idle speed is compared to the target idle speed and the ECU then adjusts the idle control device to correct for the difference between the two.
- Able to adjust idle when additional load from engine fans, power steering, or air-conditioning use is detected.
- A start-up step table in which the tuner can specify an extra amount of opening by the idle control device during engine starting to help the engine start easier.
Electronic Throttle Control
- Support for electronic throttle bodies and foot position sensors.
- Uses a 3D electronic throttle target table with configurable axis in which the desired percentage of throttle opening is specified by the tuner.
- Capable of having a throttle position that does not match the foot position. Useful for helping maintain traction.
- Up to three switchable electronic throttle target tables for different driving conditions. Useful for switching to a more aggressive or gentle throttle response.
- Multiple safety condition checks that are continuously carried out to monitor the electronic throttle system for faults. Upon a fault being detected the system restricts the engine speed.
- Two boost control modes:
- Open loop mode in which the ECU sets the wastegate solenoid duty cycle based upon the wastegate duty cycle table which the tuner has setup.

Chassis And Body
- Cruise Control - uses the electronic throttle body to achieve and maintain the set vehicle speed.
- Lockouts for minimum vehicle speed, maximum vehicle speed, and maximum acceleration rate.
- Cruise control switches can come into the ECU over analog channels, digital input channels, or over a CAN bus.
- Gear Detection - support for three different modes of gear detection:
- RPM/Speed mode where the ECU compares the engine speed to the vehicle speed to determine the current gear.
- CAN mode, where the current gear comes to the ECU over a CAN bus from the transmission computer.
- Analog Position Sensor mode where the ECU monitors the voltage on an analog input channel and knows the gear from the volt/gear information filled in by the tuner.
- AC Clutch control - the ECU has two different modes of air conditioning control:
- Basic - for use in systems where an air conditioning controller exists. The ECU receives an air conditioning request from the air conditioning controller, it then engages the air conditioning compressor clutch.
- Full - for use in systems where an air conditioning controller does not exist. The ECU receives an air conditioning request from a switch or over CAN, it then checks the system high and low pressure and evaporator temperature, if these are within the limits set by the tuner it engages the air conditioning compressor clutch.
Both air conditioning modes have a configurable lockout based upon throttle position, intake manifold pressure, or injector duty cycle.
- Anti Theft - for interfacing with factory or aftermarket alarm and keyless entry systems. When anti theft is active the engine will not start. Capable of accepting input from a digital input or over a CAN bus.
- Speed Sources - for configuring the vehicles wheel speed sources. Wheel speeds are able to come into the ECU over digital inputs channels or a CAN bus. Speed sources also includes settings for slip and speed correction.
- Starter control - four different modes for starter motor control including:
- Start/Stop where one switch or button is used for starting and stopping the engine.
- Touch start where the driver momentarily presses a button or turns the key and the engine keeps cranking until started or a tuner set amount of time is reached.
- Transmission - settings for transmission input shaft calibration. The input shaft speed can then be compared to engine speed and the slip is capable of being displayed and logged.
- Two CAN modules for communication with factory and aftermarket devices.
- Custom CAN configuration allowing tuners and end users to add support for new CAN devices.
- Serial connection for tuning of ECU and sending ECU data to aftermarket displays.
- USB connection for tuning of ECU.

- Select the rate each parameter will be logged at from 0.5 to 100 times per second.
- Specify the conditions under which ECU logging will be active. Options include a switched input, an engine speed level, a throttle position, an intake manifold pressure or a combination of all and more.
- Set how long the ECU will continue logging for once the activation conditions are no longer met.
- ECU Logging loops, so once all the internal logging memory is used the ECU logging will start to overwrite the oldest data.
