V-tech Tuning PowerBOX Diesel PDF User manual

PowerBOX (power modules) belong to the category of products, which modify controlling signals and sensor signals outside the engine computer
(ECU). They have been designed to emulate the chip tuning effects. Such modifications may be performed in certain situations, e.g. whenever the car computer is a non-reprogrammable type. The Diesel PowerBOX works with Diesel engines of the following types: Common Rail, VP-37, VP-44, PD and NipponDenso. We offer over 20 Power-Box models equipped with factory plugs, which service several hundred car models of the largest car manufacturers from Europe, USA, Japan and Korea.

WHAT DO YOU GAIN?
When connected to the engine Diesel PowerBOX increases the torque and power by up to 20% in comparison to the serial values. The level of additional power can be controlled by choosing one from the 10(*) programmes offered by the device. The device can also be completely switched off. The modified parameters of the engine do not affect its wearability. One should remember to disconnect the PowerBOX device before visiting a car manufacture’ authorised service centre.

Take off the engine cover. Find the fuel pump interface, double-rowed, with 8 or 10 pins (depending on the model). Photo 1 Disconnect the fuel pump interface and connect the adapter delivered with the module between its plugs. Photo 2 Find the air mass sensor in the car (it is placed in the intake system, behind the air filter). The loose black cable coming out from the module should be connected to the pin of the th the highest number in the air mass sensor plug (the 5 or 6 pin depending on the sensor version).

OTHER
In the case of other engines powered with the VP-37 pump there are no industrial interfaces allowing the non-invasive installation of the module.
The module installation requires soldering five module cables to the car wiring harness. The example of connecting the module to the wiring harness in the Mitsubishi Pajero 3.2 DiD is shown in Photo 4.

ENGINES WITH BOSCH PSG16 PUMP – OPEL/SAAB Take off the engine cover. Dismount the EGR valve (do not disconnect the cooling fluid lines).
Disconnect the pump interconnection, on the right side of the pump. Below this plug, there are two black cables between the fuel lines. The
fused black cable should be connected to the cable which is closer to the cooler. Solder the yellow cable to the cable coming to pin 33 in the pump plug (disconnected earlier). Connect the red cable to the positive battery post and the black cable to the negative battery post.

ENGINES WITH A BOSCH PSG5 PUMP Take off the engine cover. Connect the fused red cable to the injection pump. This cable should be connected to the upper right cable from the four black cables located near the main inter-connection of the pump. Connect the yellow cable to the acceleration pedal signal. Connect the red cable to +12V. Connect the black cable to the mass. The example of the installation in the Nissan Patrol 3.0 DI is shown below.
