Tuning boxes for turbodiesel engines
P-Tronic has developed six distinct devices to cover the full range of diesel injection technologies, from the earliest electronic generations through to the latest multi-injector Common Rail systems. Each tuning box is engineered to work in perfect harmony with the vehicle, fully respecting its original functions: driving modes, automatic gearbox, driver assistance systems. Compatible engine codes include: TDI, CDI, d, BlueHDi, Blue dCi, dCi, HDi, e-HDi, MultiJet, CDTI, TDCi, EcoBlue, CRDi, D-4D, JTDM, BlueTEC...
The 6 devices in the diesel range

Common Rail - multi-injector
This range fits vehicles equipped with a Common Rail diesel engine (Bosch, Delphi, Denso, Siemens) where effective optimisation can only be achieved through an individual connection at injector level or via a multiple connection. Despite its complex internal structure, installation requires no specialist skills. The box ensures perfect harmony with the vehicle, fully respecting all original functions: driving modes, automatic or automated gearbox, driver assistance systems.
Vehicle examples: Ford Ranger 2.0 Bi-Turbo, Toyota Hilux VIII 2.4 D, Mercedes E-Class 220d, Audi SQ7 4.0 TDI, Mitsubishi L200 2.4 DI-D, Peugeot 5008 1.5 BlueHDI, Volvo V60 II 2.0 D3, BMW X7 M50d, Land Rover Discovery Sport 2.0 D MHEV, John Deere 6R 195 6.8…

Common Rail - dual connector
Most brands in our catalogue offer at least one Common Rail turbodiesel compatible with this box. The technology works by recontrolling fuel injection via a dual connector fitted in series at the main common rail sensor. This approach makes installation as straightforward as possible, delivering impressive results in both performance gains and fuel savings.
Vehicle examples: BMW 320d, Volkswagen Tiguan 2.0 TDI, Audi Q3 35 TDI, Fiat Ducato 2.3 D Multijet, Ford Ranger 3.2 TDCI, Land Rover Defender 2.2 TD, Renault Kadjar 1.6 dCi, Skoda Kodiaq 2.0 TDI, Toyota Land Cruiser 3.0 D-4D, Mercedes C-Class 180 CDI, Volvo Penta D Series…

Common Rail - rail pressure
Available for certain Common Rail turbodiesel engines, the P-Tronic PTA box delivers a reliable and effective power increase. This is achieved by adapting injection volume, injection timing and rail pressure, all within the margins defined by the manufacturer.
Vehicle examples: BMW 3 Series 330d, BMW X5 3.0sd, Fiat Ducato 2.0 JTD, Audi A6 3.0 TDI, Mercedes G-Class 270 CDI, Mercedes Sprinter 316 CDI, Peugeot 406 2.0 HDI, Alfa Romeo MiTo 1.3 JTDM, Land Rover Range Rover III 3.0 TD…

Bosch VP injection pump
Bosch VP injection pumps feature a radial piston distributor that requires a highly specific tuning box. P-Tronic developed a dedicated device using original manufacturer slide connectors for a perfect fit. The box receives, analyses, optimises and retransmits digital data network signals in real time. Performance gains result from active priming of the injection pump. P-Tronic is one of the very few manufacturers to offer this solution.
Vehicle examples: Nissan Patrol GR 3.0 DI, Audi A6 2.5 TDI, Ford Transit 2.4 TDE, Opel Frontera 2.2 DTI, Case IH CVX 1135 6.6, Massey Ferguson MF 7400 7465, John Deere 6000 Series 6820 6.8…

Bosch / Delphi unit injectors
Developed for engines fitted with Bosch or Delphi unit injectors, the P-Tronic Digital IP box achieves its power increase through direct priming induced by the characteristics of the injection solenoid valves. The box connects directly to the unit injector, calibrated to the initial parameters of each specific engine.
Vehicle examples: Audi A4 2.0 TDI, Audi A3 2.0 TDI, Volkswagen Passat 1.9 TDI, Seat Leon 2.0 TDI, Skoda Octavia II 1.9 TDI…

Early turbodiesel generations
The P-Tronic APT is designed for early-generation turbodiesel engines with electronic injection of the Lucas or Bosch type. It delivers excellent performance gains and fuel consumption reductions through a dynamic adjustment of the injected fuel quantity via indirect priming of the pump.
Vehicle examples: Volkswagen Transporter 2.5 TDI, Audi A3 1.9 TDI, Nissan Navara 2.5, Volvo Penta KAMD 44…
