Inicialização inicial:
After all connections are made, reconnect the battery. Observe the LED display for any warning indicators. Consult the troubleshooting section if any issues arise.
Operating the Digital 6-Plus
The Digital 6-Plus offers several adjustable features to optimize engine performance.
Rev Limit Adjustment:
The unit features rotary switches for setting two distinct rev limits in 100 RPM increments. These limits can be used for launch control or over-rev protection. Refer to the specific instructions for setting these limits based on your engine's requirements.

Músicastage Retard:
This feature allows for a single stage of timing retard, commonly used with nitrous oxide systems or for fine-tuning top-end performance. Ensure proper calibration to avoid engine damage.
Start Retard:
The start retard function reduces ignition timing during cranking, making starting easier and reducing stress on the starter motor and flywheel. This feature is automatically engaged during engine start-up.
Manutenção
The MSD Digital 6-Plus Ignition Control is designed for durability and requires minimal maintenance. However, periodic checks can ensure continued optimal performance.
- Inspeção de fiação: Periodically inspect all wiring connections for signs of wear, corrosion, or loose terminals. Ensure all connections remain secure.
- Limpeza da unidade: Keep the unit clean and free of excessive dirt, oil, or debris. A clean unit allows for better heat dissipation.
- Segurança de montagem: Verify that the unit remains securely mounted and that mounting hardware is tight.
