Dynamic Timing Spacer Boost Pin Plate for Land Rover Range Rover 200 300 Tdi

Dynamic Timing Advance Spacer Kit + Tuning Boost Pin for Audi, VW, Volvo 740, 760 with Bosch VE Injection Pump

What does the dynamic timing advance spacer kit do?

Using this spacer kit increases the range of the standard dynamic timing advance in the VE pump.
Dynamic timing advance is a mechanism used to advance the start of fuel injection as engine speed increases, thereby allowing more time for proper combustion.
The additional dynamic valve timing provided by this spacer kit will improve fuel combustion at higher RPMs while maintaining static valve timing to the standard specification, thereby preserving low-RPM performance.


Why BOOST PIN?

LDA—this is a mechanism in the TD fuel injection pump that reduces the fuel dose at low RPMs and when boost pressure is low or absent. Conversely, as boost pressure increases, it automatically delivers a larger fuel dose.
In the animation above, we see a screw—the so-called PIN reader—which moves to the right when the accelerator pedal is pressed, causing the fuel dose to increase. However, it is clear that the movement of this screw is limited by the PIN—this is the very essence of how LDA works. The further the PIN reader is able to move, the more fuel will be delivered.
The animation shows that the PIN diaphragm is not symmetrical; the notch on one side is larger than on the other. Thanks to this design, we can adjust the fuel delivery when boost pressure occurs. By enlarging the cutout on the PIN’s reader side, we increase the fuel dose, and by rotating the PIN with the smaller cutout toward the reader, we cause the reader to extend outward, thereby reducing the fuel dose.

    The kit includes:
1 x Tuning Boost Pin;
1 x aluminum spacer washer;
2 x O-rings;
2 x Allen screws with washers;
3 x spacer washers.

Compatibility:

Suitable for all 200 and 300 TDI engines:

Land Rover Defender
Land Rover Discovery
Range Rover

For 300 TDI models with electronic control, a software update is required. Your pump must have a square diaphragm housing as shown in the photo.
