Upgrade the throttle response of your Alfa Romeo 159 (939_) 2.4 JTDM (engine codes 939AXD12, 939AXD1B) with the advanced DTE PedalBox Accelerator Pedal Tuning module.

The 2.4 JTDM five-cylinder turbo diesel engine delivers impressive torque and smooth power delivery. However, factory electronic throttle mapping can feel slightly delayed during initial acceleration. The DTE PedalBox optimizes the accelerator pedal signal in real time before it reaches the ECU, resulting in:

• Sharper throttle response

• Faster acceleration feel

• Reduced turbo lag sensation

• Improved pedal precision and overall drivability

The PedalBox does not increase engine horsepower and does not modify ECU software. It enhances throttle sensitivity only, maintaining full compatibility with OEM systems and safety features.

✅ Plug-and-Play Installation

• Connects directly to the original accelerator pedal harness

• No cutting, soldering, or wire splicing required

• No ECU remapping or coding necessary

• Fully removable and reversible

Installation typically takes just a few minutes.

✅ Selectable Driving Modes

Customize throttle characteristics to suit your preference:

• City Mode – smooth and progressive response

• Sport Mode – noticeably sharper acceleration

• Sport Plus Mode – maximum responsiveness

• Standard Mode – restores factory throttle mapping

Each mode includes multiple fine-tuning levels. The integrated memory function saves your last selected setting when restarting the vehicle.

Manufactured in Germany by DTE Systems, the PedalBox ensures premium quality and seamless integration with your Alfa Romeo 159’s electronic throttle system.
