GCU 700 – Integrated Valve Block

Description

The GCU700 is tightly packaged pneumatic valve block with a built in sophisticated transmission controller and logger. Weighing in at only 707g, the custom housing is CNC machined from billet aluminium and anodised for extra durability and protection. Connectivity is through a commonly available and durable 26 way connector. Communication link is via a simple direct USB connection and programming is done through easy to use bespoke Shiftec software which features ready set up tabs and templates. Vehicle connectivity may either be hard wired or linked over a CAN system.

GCU700 allows sophisticated closed loop 3 stage control over the shift strategy and the ability to cope with ‘off condition’ shifts as well as options to suit different gearbox lay outs. Inbuilt burst enabled data logging allows GCU700 to maximise data storage space. This combines with full diagnostics and live state machines to allow simple set up and analysis. Data may also be transmitted to vehicle data loggers.

GCU700 is available in two versions, a 3 Way variant which supports mechanical throttle blippers and a 2 Way variant for use with Drive By Wire electronic throttles.
