At the beginning of a test a pre-determined RPM value must be approached ('Test gear' / Gear
transmission close to 1:1) while in a specific gear. This RPM value will be stored.
During the performance test the software will convert the roller’s current RPM into engine RPM.
(Please note: The calculated RPM will only correspond if the vehicle is driven in the 'test gear'.)
Automatic transmission vehicles without converter lockup cannot use the driving trial method, be-
cause the engine RPM deviates due to converter slip.
OBD Module
The RPM is read from the OBD data.
Oil Temperature Probe (Optional)
Driving trials should only be done when the engine is warmed up to operational temperature. The
oil temperature meter is used to determine the oil temperature and to monitor it during the testing
procedure.
Oil temperature probe for car and truck, with
variable length (100 to 1500 mm), with plug and
6 m supply line.
Attachment:
Position (C) on the interface box.
2.7.2
Environmental Module (Standard)
The environomental module is used to record the environmental data (Plug-in card CAN PTH).
Fuel temperature (Optional)
Intake air temperature
Ambient temperature
Air pressure
Humidity
Fuel Temperature (Optional)
The fuel temperature is recorded using the interface box and the fuel consumption device and and
can be used as additional information for the fuel consumption measurement.
Intake Air Temperature
The intake air temperature is recorded using the interface box and is used for projection of the
engine performance based on DIN 70020, EWG 80/1269, ISO 1585, SAE J1349 or JIS D1001.
Ambient Temperature
The ambient temperature is recorded using the interface box.
