Upgrade the throttle response of your Alfa Romeo Spider (939_) 2.4 JTDM (engine codes 939EXD1B, 939EXD12) with the advanced DTE PedalBox Accelerator Pedal Tuning module.

The 2.4 JTDM five-cylinder turbo diesel engine delivers strong torque and refined performance, but factory electronic throttle calibration can feel slightly delayed during 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 engine horsepower and does not alter ECU software. It refines throttle sensitivity only, ensuring full compatibility with OEM engine management and safety systems.

✅ 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 only a few minutes.

✅ Adjustable 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 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 build quality and seamless integration with your Alfa Romeo Spider’s electronic throttle system.
