Air Pressure
The air pressure 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.
Humidity
The humidity 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.
The current air temperature , ambient pressure and relative humidity is included in the
calculation with the given standards (DIN 70020, EWG 80/1269, ISO 1585, SAE J1349 and JIS
D1001)
2.5.3 OBD Module (Optional)
The OBD module is used for recording the OBD data (Plug-in card CAN OBD Module). This OBD
data is different depending on the vehicle manufacturer.
Attachment:
• Position (OBD) on the interface box (see section "Description of the Interface Box").
2.5.4 Pressure/Temperature Module (Optional)
The pressure/temperature module is used to record 2 temperatures and 2 pressures (Plug-in
card CAN P2T2).
Pressure 1 + 2
Pressure 1 +2 is user specific. The test range stretches from– 0.9 to + 4.0 bar and can for
example be used to determine the intake pressure, turbocharger pressure, etc.
Exhaust Gas Temperature
The exhaust gas temperature is used as monitor check of the combustion process and to judge
its quality.
The high temperature sensor consists. of a Ni-Cr-Ni thermo element with compensation line.
The measurement range stretches from 0 to 1000 °C.
