For car enthusiasts, installing a 6LS MSD ignition system is a great way to improve the performance of their engines. This article will guide you through the wiring process to help you get the most out of your 6LS MSD ignition system.
What is the 6LS MSD Ignition System?
The 6LS MSD ignition system is a programmable ignition controller that allows you to tailor the ignition curve to your specific engine setup. The system is designed to work with a carbureted engine and is compatible with most factory and aftermarket distributors.
The 6LS MSD ignition system features a number of benefits, including:
- Improved throttle response and acceleration
- Increased power and torque
- Better fuel economy
- Reduced emissions
The Wiring Process
Before you begin the wiring process, it’s important to ensure that the battery is disconnected and all electrical components are grounded. Once you’ve taken these precautions, follow these steps:
Step 1: Identify the Necessary Wires
The 6LS MSD ignition system requires several wires to function properly. These include:
| Wire Color | Function |
|---|---|
| Red | Battery Positive (+12V) |
| Black | Battery Negative (Ground) |
| Orange | Trigger Input (Connects to Distributor) |
| Purple | Ignition Output (Connects to Coil) |
Step 2: Connect the Wires
Now that you’ve identified the necessary wires, it’s time to connect them. Follow these steps:
- Connect the red wire to a source of +12V power. This can be the positive terminal of the battery or a fuse box.
- Connect the black wire to a good ground. This can be the negative terminal of the battery or a suitable chassis ground.
- Connect the orange wire to the distributor’s tach output or the negative side of the ignition coil.
- Connect the purple wire to the positive terminal of the ignition coil.
Once you’ve connected all of the necessary wires, you can move on to programming the 6LS MSD ignition system.
Frequently Asked Questions (FAQ)
What is an ignition curve?
An ignition curve is a set of timing values that dictate when the spark plug fires relative to engine speed and load. By adjusting the ignition curve, you can optimize the engine’s performance for a specific application.
Can I use the 6LS MSD ignition system with a fuel injected engine?
No, the 6LS MSD ignition system is designed specifically for use with a carbureted engine.
Do I need to adjust the ignition timing after installing the 6LS MSD ignition system?
Yes, you will need to set the ignition timing to match the new ignition curve provided by the 6LS MSD ignition system. Failure to do so can result in poor performance and potentially engine damage.
Can I use the 6LS MSD ignition system with a distributorless ignition?
No, the 6LS MSD ignition system requires a distributor to function properly.
How do I program the 6LS MSD ignition system?
The 6LS MSD ignition system can be programmed using the MSDView software, which is available for free download from the MSD website. The software allows you to adjust the ignition curve, rev limiter, and other settings to optimize the system for your engine.
Conclusion
The 6LS MSD ignition system is a great way to improve the performance of your engine. By following the wiring process outlined in this article and programming the system with the MSDView software, you can unlock the full potential of your engine and enjoy improved power, torque, and fuel economy.
