Takeda Scorcher GT Power Module for 2021 Audi A4

Emissions Warning: This product is not designed for public highway or street use, and is only legal for formally sanctioned race use on a racing vehicle that may never be used on a public highway or street.

NEW: Bluetooth (Blue) versions are now available! This version has all the same features as the standard version, but also has Bluetooth connectivity. This allows you to eliminate the included controller for a cleaner interior and control the unit via a supported iOS or Android device! You can still use the cable and included controller if desired too.

The concept of the Scorcher GT Power Module is simple: a 30 minute install will give you a huge increase in power. There are no tuning adjustments you need to make yourself, and no "e-tune" to purchase from a professional tuner. Simply install the module and you're done! In fact, nothing about your ECU is modified by this product, and all factory ECU sensors and capabilities remain in place.

This technology works by intercepting and changing certain key signals (such as ambient pressure or airflow) that go to your factory ECU. The Scorcher GT module modifies those signals to within a range that is acceptable to your factory ECU while maximizing performance. For example, on a turbocharged vehicle, after the pressure sensor signal is changed the ECU will think it is at a higher elevation (with less dense air) and command more boost from the turbo. This elevation concept is built into the factory ECU already, so the ECU will auto adjust other parameters as needed to accommodate the higher boost.

Key Features:

• Adds significant power by altering the pressure sensor signal for turbo vehicles to increase turbo boost to improve vehicle efficiency, power, and throttle response. For naturally aspirated vehicles, the MAF sensor signal is altered instead.
• Uses high quality aluminum extrusion black powder-coated enclosure casing and factory style connectors which requires no modification to your factory harness. These factory style connectors, plugs directly into the stock wiring harness connectors and sensors.
• A LED light switch provides In-Cabin On-The-Fly power adjustments.
• On turbo vehicles, there are 4 power settings that are adjustable with one button and the LED light represents the current selection: Stock (Green), Sport (Yellow), Sport+ (Orange) and Race (Red). On naturally aspirated vehicles, there is only one on/off button.
• 100% tested for proper protection. These modules work amazingly on stock vehicles or ones modified with simple bolt-ons.
• Bluetooth Versions: Bluetooth 4.0 capable and can connect to most iOS or Android devices. Allows control of the module while being in the vehicle cabin without running any wires through the firewall. The aFe POWER SCORCHER BLUE app is free on the Apple App Store and Google Play Store and allows your smartphone device to become a handheld remote for the module. It also displays turbo boost gauge (MAP), allows you to customize each power mode, upgrade to the latest revision, and even measure 0 to 60 and 1/4 mile times!
• Leaves no trace on ECU (no footprint) because nothing is modified.
