Default Vi-pec V44 Stand alone ECU pnp MIATA

Hi folks i sell my VIPEC ECU because my ex programmer was always out of business.
Never ask to phone calls etc ......
Here in Greece i have limited choices so the best solution for my miata is my friend Reverant and his MS3.

This ecu is Autronic similar , (same designer and programmer + almost exactly same tuning software ) supports all Miata models with factory sensors, alternator,vvt, A/C etc etc etc.

Comes with

Boomslang adapter(vipec to miata) that fits to 99 ecu (i think is easy to change it at any year)

Iat sensor

Vipec to USB connection cable

PRICE $1400 + $60 worldwide shipping.



V44 Model ECU

Click Image For Larger View

The ViPEC V44 is our budget model. Despite this, the V44 is very capable with control of up to four variable cams, 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 setup to provide a different boost in each gear or switch between boost control tables.
