3.2.4.1.3 Engine load sensor
Two engine load sensors called ‘Engine load 1’ (for TPS = throttle position sensor) and ‘Engine load
2’ (for MAP = manifold absolute pressure sensor) can be connected. Even a MAF sensor (mass air
flow meter) can be connected (not recommended). Please note that certain combinations will
result in the exclusion of some options.
The use of two load sensors for most N/A and all turbo-charged engines is higly recommended.
Some settings in the software are always related to TPS and some to the MAP-sensor. However there
is the possibility to select on which sensor (TPS, MAP, combination TPS/MAP) the main load tables
are linked to. In the picture above you can see all the possible combinations.
The possible combinations are explained below.
➢ Main Load is: TPS
All the load tables included lambda target are linked to TPS value.
This is normally used for N/A engines with throttle bodies.
➢ Main Load is: MAP
All the load tables included lambda target are linked to MAP value.
This is normally used for turbo/supercharged engines .
➢ Main Load is: TPS + MAP as boost correction table
Not available for MP25(M) and MA25(M).
➢ Main Load is: TPS + MAP as boost correction factor
The ignition load table and lambda target are linked to MAP value (the ignition table for a
turbocharged and supercharged engine should always be linked to MAP). The injection table
however is linked to TPS and works in combination with the boost correction factor to determine
the main fuel injection time.
