The GReddy Sirius Control Unit required to operate all GReddy Vision gauges, Meter gauges, and Unify Sets in the Sirius ecosystem. The Sirius Control Unit acts as the central processing hub of the GReddy Sirius system, receiving signals from sensors and distributing data to connected gauges and displays.
Without the 16001721, individual Sirius gauges will not function. It is a universal part compatible with all GReddy Sirius Vision, Sirius Meter, and Sirius Unify products regardless of the specific vehicle application. Whether you are building a complete Sirius gauge setup or adding to an existing system, the 16001721 is the required foundation of the entire setup.

GReddy, manufactured by Trust in Japan, is one of the most recognized names in Japanese performance tuning. GReddy produces turbochargers, intercoolers, exhaust systems, gauges, electronics, and chassis components for a wide range of sport compact and performance vehicles. The GReddy Sirius gauge system is a modular multi-gauge platform designed for high-performance and track-oriented builds where precise real-time monitoring of engine parameters is critical.
What is the GReddy 16001721?
The GReddy 16001721 is the Sirius Control Unit, the required central hub for all GReddy Sirius gauge systems. It processes sensor data and distributes readings to connected GReddy Sirius Vision gauges, Sirius Meter gauges, and Sirius Unify Sets. No GReddy Sirius gauge will function without the 16001721 control unit installed.
Is the GReddy 16001721 required for every Sirius gauge?
Yes. The 16001721 is required for all GReddy Sirius Vision, Sirius Meter, and Sirius Unify products. It is the central processing unit of the Sirius ecosystem and a mandatory component of any Sirius gauge installation. Only one control unit is needed to power and manage multiple Sirius gauges simultaneously.
How many GReddy Sirius gauges can one 16001721 control unit support?
One GReddy 16001721 Sirius Control Unit can support multiple Sirius gauges and displays simultaneously. The specific number of channels and compatible gauge combinations depends on the Sirius product versions. Refer to the GReddy Sirius system documentation or the individual gauge instruction sheets for details on the supported configurations for your specific gauge lineup.
Is the GReddy 16001721 universal or vehicle-specific?
The GReddy 16001721 is a universal part. It is compatible with all vehicles for which GReddy Sirius gauge sensors are available. The control unit itself does not require vehicle-specific programming. Sensor selection and installation are what determine the vehicle-specific configuration of the overall Sirius system.
Where is the GReddy 16001721 typically mounted?
The 16001721 can be mounted in the engine bay or inside the cabin depending on the specific installation and sensor routing. The compact form factor allows flexible mounting. Most installations place the control unit close to the primary sensor inputs, either near the engine or in the footwell area, with harness routing to the gauge displays in the cabin.
What GReddy Sirius gauges are compatible with the 16001721?
The 16001721 is compatible with all GReddy Sirius Vision gauges, Sirius Meter gauges, and Sirius Unify Sets. This includes oil temperature, oil pressure, water temperature, boost, EGT, fuel pressure, and other parameters available in the GReddy Sirius gauge catalog. Confirm compatibility between the specific gauge model and the 16001721 using GReddy's product documentation.
Is the GReddy 16001721 sold separately from the gauges?
Yes. The 16001721 is sold separately as a standalone unit. Some GReddy Sirius Unify Sets include the control unit as part of a bundled package, but it is also available individually for customers expanding an existing Sirius system or replacing a control unit.
Does the GReddy 16001721 include a warranty?
GReddy products are covered by GReddy's standard manufacturer warranty. Warranty terms and duration should be confirmed with GReddy at the time of purchase. Keep proof of purchase for warranty claims.
