Syvecs GDI4 Stand Alone ECU

£2,700.00 (+VAT)

The Syvecs GDI4 Stand Alone Engine Management System (ECU) is the perfect solution for integrated direct injection engine management. Based on the highly popular S8 architecture, the GDI4 just has less inputs and outputs for those GDI applications that don’t require the complexity of the full S8.

Description

The Syvecs GDI4 Stand Alone Engine Management System is designed to directly control and drive all Gasoline Direct injectors including parts from Ford, GM and Bosch (including Bosch Motorsport types) without the need for an external driver box. As standard it caters for 4 Cylinder engines but we can provide for more cylinders via the use of the Syvecs S12 ECU and GDI Boxes.

In addition, the Syvecs GDI4 is cased in a sealed aluminium billet unit and comes with 1 x waterproof connectors offering 88 pins.
