🔧 Product Overview
The Round CAN Display combines several functions in one compact gauge:
- Large digital gear indicator
- Live engine and transmission dashboard
- Configurable CAN-bus gauge
- Integrated CAN traffic monitor
- Bluetooth configuration
- Custom DBC support
- Built-in software-activated termination resistor
Its traditional round-gauge format makes it easy to integrate into dashboards, gauge pods, center consoles, and custom instrument panels.
⚙️ ZF 8HP CAN Display and Transmission Integration
The display is particularly suited to vehicles fitted with a ZF 8HP automatic transmission.
When used with a compatible ECU or transmission controller, it can display:
- Current gear
- Shifter mode
- ZF 8HP operating mode
- Transmission temperature
- Vehicle speed
- Engine RPM
- Engine torque
- Additional drivetrain data
A dedicated full-screen gear page provides a large, easy-to-read gear indication for road, track, drift, rally, and drag-racing applications.
