Some of the features that come in the software include:

• Tuning tools, QuickTune Mixture Table, Maths Key.

• Launch Control (two step rev limiter based on vehicle speed).

• Flatshift (change gears without clutch at WOT using standard gearbox).

• Antilag (keep turbocharger on boost during gear changes) with turbo cooldown function.

• Selectable ignition tables.

• Up to 440 Zone Fuel Table with configurable load and RPM centres. MGP, MAP and load options.

• 5D Fuel Mapping.

• Many correction tables for precision fuel & ignition adaption.

• Digital Trigger Decoding.

• Reluctor, Optical or Hall Sensors.

• Programmable filtering and arming thresholds.

• Configurable trigger patterns or preset triggering options, such as, Multi tooth, missing tooth, Subaru, Nissan, Mitsubishi, Ford, Mazda, GM, Suzuki and Toyota triggers. Software selectable trigger angle.

• Support for up to four rotor engines with ignition split.

• Dedicated idle control with additional settings for better adaption to changing operating condition and a more stable idle.

• Open loop boost control, switch boost pressures, different boost in each gear.

• A/C compressor control.

• Closed loop narrow band.

• Closed loop wideband at WOT.
