Traditional ECU Tune vs. Piggyback Tune

Modern vehicle programming prioritizes engine efficiency but can severely limit performance from the factory. A traditional ECU tune is an option to improve driveability, however, it’s a risky choice. Custom tuning flashes the ECU and leaves a permanent trace that can void your factory warranty and negatively impact your resale value.

If you’re like the majority of enthusiasts who are hesitant to tune their car or truck, and as most ECUs are locked from tuning, you’re probably wondering how you can unlock more horsepower quickly and safely. This is where the aFe POWER Scorcher Power Module comes into play. This plug-and-play module carries different tunes, and offers a safe, reversible alternative by enhancing performance without flashing the ECU.

How does the Scorcher Power Module Work?

The Scorcher Power Module is a plug-and-play piggyback tuner that enhances performance by modifying sensor signals in real time without altering your ECU software. These sensors are installed inline with factory sensors, and intercept the signals being reported back to the ECU. Designed primarily for turbocharged gas and diesel vehicles, the Scorcher Power Module increases boost pressure and fuel delivery, leading to instant improvements in performance and responsiveness.

How the Scorcher Improves Your Drive:

✅ Instant Power Gains – Significant horsepower and torque gains at the press of a button.
✅ Eliminates Throttle Lag – Increased responsiveness for your vehicle.
✅ 100% Reversible – Simply unplug it to return your vehicle to stock.
✅ Undetectable – Leaves no trace on the ECU.
✅ Safe for Daily Driving – Extensively tested to operate within factory safety limits.

aFe POWER Scorcher Modules offer the most horsepower per dollar. Installation is quick and easy—just plug it in for immediate performance gains. And if needed, removal is just as simple, restoring your vehicle to stock with no detectable changes.

Performance gains can vary depending on the specific vehicle application. For example, on the 3rd Gen Tundra with a 3.4L twin-turbo V6 engine, the Scorcher BLUE delivers an impressive +93 HP horsepower and +154 lb-ft of torque in RACE mode.

During the Research and Development process, each Scorcher is rigorously tested on our in-house dyno to ensure it provides the maximum possible power without compromising engine safety. We carefully fine-tune power levels for optimal compatibility, ensure no warning lights are triggered, and conduct real-world driving tests to confirm reliability. By the time a Scorcher module reaches your hands, you can trust that it’s a safe, reliable upgrade that delivers real, dyno-proven gains. We also publish dyno charts showing horsepower and torque improvements for every application.

Step-by-Step Installation (Example: 3rd Gen Tundra)

 While sensor locations vary by vehicle, the general process is as follows:

1. Turn off the vehicle before disconnecting any sensors.
2. Remove the engine cover to access the MAP and T-MAP sensors.
3. Connect the Scorcher module between the boost sensors and ECU harness.
4. Attach the power and ground wires to the battery.
5. Secure the module in a dry, cool location.
6. Route the LED switch into the cabin for manual control or use the Scorcher Blue app for adjustments.

Frequestly asked questions:

1. Is the AFE Scorcher module safe for my engine?
   1. Yes, the AFE Scorcher has been extensively tested to ensure it is safe for your engine, providing performance gains without compromising reliability.
2. Can I use Scorcher with other mods?
   1. The Scorcher has been tested with all other AFE products, but we haven’t tested it with parts from other brands. It pairs excellently with AFE Intakes, which don’t require a traditional tune, to maximize incoming air. Other popular pairings include Throttle Bodies, Throttle Body Spacers, Charge Pipes, and Exhausts.
3. Will using a piggyback tuner void my vehicle’s warranty?

   1. The Scorcher Module is a plug-and-play device that does not flash your ECU or leave a trace. Under the Magnuson-Moss Warranty Act, a vehicle manufacturer cannot void your warranty solely because of an aftermarket part unless it’s proven to be the cause of a failure (15 U.S.C. 2302 (C)).

4. What if I don’t see a Scorcher for my vehicle?
   1. Availability varies by application. We primarily develop Scorchers for turbocharged vehicles due to the greater boost potential, but we’re always expanding our offerings. If you don’t see a Scorcher for your vehicle, feel free to contact us as we may be able to give you more information. If you’re local to Corona, check if your vehicle is on our Vehicle’s Needed list for product development.
5. Are AFE Scorcher modules made in the USA?

   1. Yes, AFE Scorcher Modules are proudly manufactured in Indiana, USA.

6. Do I need to use higher-octane fuel with the AFE Scorcher tuner?
   1. For select applications, using 91 octane or higher is recommended. For more details, check the product information page for your specific vehicle’s Scorcher module.
7. Are there any common issues or check engine lights associated with the AFE Scorcher module?
   1. Most check engine lights (CELs) are caused by improper installation and can be easily resolved. If you experience any issues, contact our Technical support, and we’ll guide you through the solution.
