Log
Saving values of the sensors and parameters like time of opening the injectors, enrichments or actual RPM, in a
log is an key activity in order to “tune” the engine. While analyzing a log one can optimize parameters / tables or
find the cause of a not correct work of the engine.
Logged signal Description
TPS (Throttle position sensor) Value from the sensor of throttle position (in %)
CLT(Coolant temperature) Coolant temperature
Analog Out Voltage value on the Analog Out output
Freq. In(Frequency in) Input frequency in Hz on the Frequency In input
ASE(Afterstart Enrichment) The current Afterstart enrichment value (100% means no enrichment)
Ignition Angle Current value of the ignition angle modification (0 – no modification,
negative value – retarded ignition, positive value – advanced ignition
TPS Rate(dTPS) Current value of the angle change of the throttle position (%/s)
Acc. Voltage(Accumulator Voltage)
Voltage in the car’s electric installation
MAP(Manifold absolute pressure) Absolute manifold pressure (in kPa)
IAT(Intake air temperature) Intake air temperatur
RPM(Revolutions per minute) Current engine speed
