i44 - Four Channels of Fuel and Ignition control

The starting model of the Vi-PEC range, the i44 is fully featured and very flexible.

The Vi-PEC i44 is our smaller model. Despite this, the i44 is very capable with control of up to four variable cams and support for engines up to twelve cylinders. Software has very flexible options over how the inputs and outputs are controlled, and allows the user to design their own functions to control all sorts of devices. Precise control of injectors and ignition angle are guaranteed at very low or high RPM or manifold pressures. A very high level of protection from interference and tolerance of trigger input errors has been built into this ECU, ensuring a smooth running engine even under the most demanding conditions.

  • Motor Sport features include: Antilag, Flatshift, Launch control and traction control in first gear.
  • Individual Cylinder Knock control, when external digital knock amplifier used.
  • Peak and hold injector drivers. Both the peak Amps and hold Amps can be set separately in the software for optimum injector control.
  • Closed loop control of idle speed and boost pressure makes for a "factory" idle speed stability, and precise control of boost pressure. Boost control can be set up to provide a different boost in each gear or switch between boost control tables.
