The Emtron SL6 is a wire-in engine control unit built for 6-cylinder engines. It steps up from the SL4 with a second CAN bus, giving more headroom for CAN-connected peripherals — lambda controllers, displays, PDMs — on busy motorsport builds. The same billet aluminium enclosure and Ethernet-based Emtune tuning platform apply across the full SL range.

Engine Management Features
- Variable Valve Timing (VVT) and Variable Valve Timing Electric (VTiE)
- Drive by Wire (DBW) throttle control
- Dual boost control
- Gearshift control
- Flex fuel / ethanol content
- Launch control and traction control
- Wideband lambda via CAN (requires separate controller — see below)
Lambda Controller
The SL6 does not have a direct wideband lambda input. Use a CAN-connected controller:
- Emtron ELC1 CAN Lambda Controller — single channel
- Emtron ELC2 CAN Lambda Controller — dual channel (recommended for 6-cyl builds)
Accessories
- Emtron SL ECU Connector Kit — mating connector set for the SL6 harness
- Ethernet RJ45 Socket, Unterminated 2 m — loom-integrated panel socket for Ethernet tuning (preferred)
- Emtron ECU Tuning Cable — Ethernet patch cable for laptop connection (alternative)
- Emtron ED7 Display — CAN-connected dash display
