The legendary BMW E36 is known for its performance and potential for modification. One of the most sought-after upgrades is the “E36 Flame Tune,” which delivers aggressive pops, bangs, and even flames from the exhaust on deceleration. This guide will delve into the world of E36 flame tunes, exploring what they are, how they work, and what to consider before getting one.
What is an E36 Flame Tune?
An E36 flame tune is a custom engine calibration that alters the fuel and ignition timing maps in the car’s Engine Control Unit (ECU). This modification allows unburnt fuel to enter the exhaust system, where it ignites, creating the signature pops, bangs, and flames. The intensity of these effects can be customized, ranging from subtle pops to dramatic fireballs.
How Does an E36 Flame Tune Work?
A flame tune manipulates the ECU to:
- Retard Ignition Timing: Delaying the spark allows some fuel to escape unburnt into the exhaust.
- Adjust Fuel Delivery: The tune can enrich the air-fuel mixture on deceleration, providing more fuel for combustion in the exhaust.
- Disable Secondary Air Injection (SAP): The SAP system introduces fresh air into the exhaust to reduce emissions. Disabling it allows for richer exhaust gases and more dramatic flames.
- Bypass Rear Oxygen Sensor: By bypassing this sensor, the ECU doesn’t detect the rich exhaust mixture and trigger a check engine light.
Customizability and Tuning Options
E36 flame tunes offer a high degree of customization. You can choose from various “pop and bang” styles, ranging from mild to aggressive. Some tuners offer options for:
- Toggle Switches: Allowing you to activate or deactivate the flame tune on demand.
- Aggression Levels: Fine-tuning the intensity of the pops, bangs, and flames.
- Flame Intensity: Controlling the size and frequency of the flames.
The Tuning Process
Most E36 flame tunes are applied through remote tuning. This involves:
- Downloading Tuning Software: You’ll receive software and instructions from the tuner.
- Reading ECU Data: Using a K+DCAN cable and a laptop or Android device, you’ll read and save your car’s current ECU data and any fault codes.
- Sending Data to Tuner: You’ll send the saved data to the tuner.
- Receiving Custom Tune File: The tuner will create a custom tune file tailored to your specifications.
- Uploading Tune File: You’ll upload the new tune file to your car’s ECU using the provided software and cable.
Considerations Before Getting a Flame Tune
While an E36 flame tune can be exciting, consider these factors:
- Legality: Check local regulations regarding exhaust noise and emissions. Flame tunes might not be street legal in all areas.
- Potential Risks: Improper tuning can damage your engine or exhaust system. Choose a reputable tuner with experience in E36s.
- Long-Term Effects: Repeated high-intensity flames can put stress on exhaust components.
Finding a Reputable Tuner
Research and choose a tuner with a proven track record of successful E36 flame tunes. Look for tuners who offer:
- Customization Options: Allowing you to tailor the tune to your preferences.
- Remote Tuning Support: Providing clear instructions and assistance throughout the process.
- Revisions: Offering revisions to fine-tune the performance after installation.
- Warranty: Backing their work with a warranty against defects.
Conclusion
An E36 flame tune can add an exhilarating element to your driving experience. By understanding how it works, the customization options available, and the potential risks, you can make an informed decision about whether a flame tune is right for your E36. Always prioritize safety and legality, and choose a reputable tuner to ensure a successful and enjoyable upgrade. Remember to check your local laws and regulations regarding vehicle modifications before proceeding with any tuning.
