The GCU501 is a cost effective yet powerful transmission controller and logger. It is packaged in a compact and durable environmentally sealed ABS casing with two mounting lugs. Connectivity is with standard DTM connectors. 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.

The GCU501 provides identical functionality to the GCU500 with the addition of TPS Input/Output control and processing which allows the GCU to control most Drive By Wire throttle systems to produce the up change torque reduction and down change blip via throttle position change.
