FAQs
What RPM limit can the 6AL-2 handle?
The MSD Ignition 6AL-2 is rated for engine RPMs up to 12,000 RPM.
What operating system is required for the Pro-Data software?
The Pro-Data software is designed for Windows-based operating systems.
Can I use this with an ignition system that doesn't use a distributor?
No, the 6AL-2 is specifically designed for distributor-based ignition systems.
How does the step retard feature work?
The step retard allows you to program a specific amount of ignition timing to be retarded (pulled back) under certain conditions, commonly used for nitrous applications.
What is the purpose of the 2-step rev limiter?
The 2-step rev limiter allows you to set two distinct RPM limits: an upper limit to protect the engine and a lower limit that can be used for launch control during drag racing.
Can I adjust timing for boost pressure?
Yes, the 6AL-2 features boost timing maps that allow you to plot ignition timing adjustments based on boost pressure, with accuracy up to 0.1% per PSI.
Does this unit come with installation instructions?
Yes, the unit typically includes detailed wiring diagrams and installation instructions. Always refer to the manufacturer's documentation.
Troubleshooting
Unit not powering on
Check all wiring connections to ensure they are secure and correctly connected to power and ground. Verify the power source is functioning.
Engine misfiring or running poorly
Review the programmed ignition curve for errors. Check spark plug wires and coil connections. Ensure the distributor is correctly phased.
Rev limiter not engaging
Confirm the 2-step limiter is enabled and programmed correctly in the software. Check the wiring to the activation switch if used.
Software not recognizing the unit
Ensure the correct USB driver is installed for the unit. Try a different USB port or cable. Restart the software and computer.
