RPM
The RPM of the vehicle is recorded by a optional piëzo clamp or RPM adapter. The standard piëzo clamp has a
diameter of 6 mm and suitable for most European vehicles. Dismount the engine cover plates of the vehicles.
- Find a location were injection pipe is straight.
-
Take care take this piece of pipe is clean and dry.
- If necessary, use sand paper to clean the injection pipe.
- Mount the piëzo clamp around the injection pipe.
- Tighten the knob of the clamp but don’t overdo.
- Place the black crocodile clamp (ground) at the injection pipe near the piëzo.
Check that the RPM is recorded correctly. If not, repeat the procedure mentioned above at a different location of the
injection pipe.
Figure 2. Placing the piëzo clamp
Remark: the piëzo clamp can not be used for all types of diesel vehicles, for example common rail diesels. Here for
you need a special RPM adapter. If you use an adapter, always follow the instructions given by the manufacturer.
Oil temperature sensor
Take care that the length of the sensor is not longer than the length of the dip stick. Move the adaptation rubber
until the length of the sensor is correct. Now place the temperature sensor in the dip stick holder of the engine.
Figure 2. The oil temperature sensor
After testing you have to remove the temperature sensor from the engine. Clean wasted oil from the engine and
temperature sensor with a clean towel.
Don’t forget to place back the dip stick !
