The top of the range V88 from Vi-PEC gives the most flexibility of all our ECUs. This computer has now been replaced by the iSeries i88

Photo%252520of%252520V88The Vi-PEC V88 is our most advanced ECU. This ECU has many features which allow it to be setup to suit various types of engine configurations. It 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.

  • Variable camshaft control for up to four camshaft. Control of camshaft position is very precise and time taken to advance from full retard to full advance is less than 1 second. Support for VVT and VANOS systems.
  • 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 setup to provide a different boost in each gear.
  • Individual Cylinder Knock control, with support for two sensors. Knock control is user definable with flexible settings to allow precise knock control.
  • E-Throttle (Electronic Throttle Control).
  • Peak and hold injector drivers are 10 amp. Both the peak Amps and hold Amps can be set separately in the software for optimum injector control. See setup screen.
