Enhance the throttle response of your Alfa Romeo 159 Sportwagon (939_) 1.9 JTDM 16V (engine codes 939BXC1B, 939BXC12) with the advanced DTE PedalBox Accelerator Pedal Tuning module.

The 1.9 JTDM 16V engine offers strong turbocharged diesel performance, but factory electronic throttle mapping can feel slightly delayed during initial acceleration. The DTE PedalBox optimizes the accelerator signal in real time before it reaches the ECU, delivering:

• 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 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 wire cutting, soldering, or splicing required

• No ECU remapping or coding necessary

• Fully removable and reversible

Installation typically takes only a few minutes.

✅ Selectable Driving Modes

Tailor throttle response to your preference:

• City Mode – smooth, progressive response

• Sport Mode – noticeably sharper acceleration

• Sport Plus Mode – maximum responsiveness

• Standard Mode – restores factory throttle settings

Each mode includes multiple fine-tuning levels. 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’s electronic throttle system.
