Description
Upgrade the throttle response of your Alfa Romeo 159 (939_) 1.9 JTDM 8V (engine code 939AXE1B) with the DTE PedalBox Accelerator Pedal Tuning module.
The 1.9 JTDM 8V diesel engine delivers strong torque, but like many drive-by-wire vehicles, it can experience throttle delay during initial acceleration. The DTE PedalBox optimizes the electronic accelerator signal in real time, resulting in:
-
Sharper throttle response
-
Faster acceleration feel
-
Reduced turbo lag sensation
-
Improved pedal precision
The PedalBox does not modify the ECU software and does not increase engine horsepower. It enhances throttle sensitivity only, ensuring full compatibility with factory engine management systems.
✅ Plug-and-Play Installation
-
Connects directly to the accelerator pedal harness
-
No cutting or wire splicing required
-
No ECU remapping needed
-
Fully removable and trace-free
Installation typically takes just a few minutes.
✅ Adjustable Driving Modes
Select your preferred throttle characteristic:
-
City Mode – smoother, controlled response
-
Sport Mode – noticeably sharper acceleration
-
Sport Plus Mode – maximum responsiveness
-
Standard Mode – restores factory settings
Each mode offers multiple fine-tuning levels. The integrated memory function retains your last selected setting after restarting the vehicle.
Manufactured in Germany by DTE Systems, the PedalBox ensures premium build quality and seamless integration with your Alfa Romeo 159’s electronic throttle system.
