Improve the throttle response of your Alfa Romeo 159 Sportwagon (939_) 1.9 JTDM 8V (engine code 939BXE1B) with the advanced DTE PedalBox Accelerator Pedal Tuning module.

The 1.9 JTDM 8V diesel engine delivers strong torque and efficient performance, but 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, providing:

• Sharper throttle response

• Faster acceleration feel

• Reduced turbo lag sensation

• Improved pedal precision and control

The PedalBox does not increase horsepower and does not alter ECU software. It refines 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 is quick and typically completed within minutes.

✅ Selectable Driving Modes

Customize throttle response to suit your driving style:

• City Mode – smooth and progressive response

• Sport Mode – noticeably sharper acceleration

• Sport Plus Mode – maximum responsiveness

• Standard Mode – restores factory throttle settings

Each mode includes fine adjustment levels, and the integrated memory function saves your last selected setting when restarting the vehicle.

Engineered and manufactured in Germany by DTE Systems, the PedalBox ensures premium quality and seamless integration with your Alfa Romeo 159 Sportwagon.
