### **Cons of the Petronix D71002 Flame-Thrower Distributors Module**
1. **Cost**
The Flame-Thrower module is not a cheap component. Depending on the retailer and any additional accessories (such as a new distributor or wiring harness), the total cost can range from **$200 to $400 or more**. This makes it a significant investment, especially for hobbyists or those on a tight budget.
2. **Requires Additional Components**
While the Flame-Thrower module itself is a powerful upgrade, it often requires pairing with other components to achieve its full potential. For example:
- A **high-performance distributor** (such as the Petronix D71001) may be needed for optimal performance.
- A **new ignition coil** (such as the Petronix Power Flash) is often recommended to complement the module.
- A **wiring harness** or **relay** may be necessary to ensure proper electrical connections.
These additional costs can add up quickly.
3. **Learning Curve for Tuning**
The Flame-Thrower module offers advanced features like adjustable timing curves, which can be overwhelming for beginners. Proper tuning requires an understanding of ignition timing, dwell, and how these factors interact with the engine s fueling system. Incorrect tuning can lead to poor performance, detonation, or even engine damage. Beginners may need to consult a tuner or spend time researching to dial in the module correctly.
4. **Potential for Overkill in Mild Builds**
For stock or mildly modified engines, the benefits of the Flame-Thrower may not be significant enough to justify the cost. If the engine is not running high-performance fueling, forced induction, or extreme compression ratios, the gains from the module may be minimal. In such cases, a simpler ignition upgrade (like a high-output coil or distributor) might be more cost-effective.
5. **Compatibility Issues with Some Engines**
While the Flame-Thrower is designed to be versatile, some older or highly modified engines may require additional modifications or adapters to work seamlessly with the module. For example:
- Engines with **non-standard distributor shafts** may need a custom adapter.
- Engines with **electronic ignition systems** (like some modern GM or Ford applications) may not be compatible without additional components.
It s important to verify compatibility with your specific engine before purchasing.
6. **Warranty and Return Limitations**
Like many aftermarket performance parts, Petronix products may have limited warranty coverage, especially if the module is installed incorrectly or used inappropriately. Additionally, some retailers may have strict return policies, making it difficult to get a refund if the module does not perform as expected.
7. **Potential for Electrical Noise**
High-performance ignition systems like the Flame-Thrower can sometimes introduce electrical noise into the vehicle s wiring harness, which may interfere with other electronic components (such as fuel injectors, sensors, or modern ECUs). This is less common with modern vehicles but can be an issue in older cars with less robust wiring.
8. **Maintenance and Wear**
While the Flame-Thrower is durable, like any mechanical or electrical component, it is not immune to wear and tear. Over time, the distributor cap, rotor, or internal components may need replacement. Additionally, the module itself may require occasional recalibration or software updates if Petronix releases new firmware.
