Key capabilities

Fuel & ignition control

  • Fully programmable fuel and ignition tables using PC-based tuning software.
  • Supports a wide variety of engine configurations when wired and configured correctly.
  • Per-table and per-parameter adjustability for cold start, warm-up, load, throttle and more.
  • Can be configured for performance or economy depending on the calibration.

Inputs, outputs & flexibility

  • Multiple analog and digital inputs for typical engine sensors (MAP, TPS, temperature, etc.).
  • Configurable outputs that can be assigned to injectors, coils and auxiliary functions where supported.
  • Capable of interfacing with a wide range of commonly used sensors when properly calibrated.
  • Compact aluminum case makes it easy to mount in tight engine bays or cabins.

Tuning & motorsport features
