MoTeC Calibration 43
Calibration
The Calibration Tables determine how the output devices should be controlled
for various sensor readings. For example the Fuel - Main Table determines
the pulse width for the Fuel Injectors for all combinations of RPM and Load.
The ECU Manager software should be used to adjust the various calibration
tables to suit the engine.
Warning Alarms
Set the Warning Alarms to warn if the engine temperature goes too high. (The
warning alarms may be set in the Functions menu).
Ensure that the engine is “On Site”
The engine must be “On Site” for changes to the table values to affect the
tuning. This means that the engine must be operating at the same RPM and
Load as the currently selected site in the calibration table.
Note that when the engine RPM (or Load) is between table sites the current
fuel value (or Ignition value etc.) is affected by the sites to either side. For this
reason, when adjusting the calibration values it is important that the engine
RPM and Load are centred on the current adjustment site to ensure that the
values from the adjacent sites have minimal influence on the value being
adjusted. Use the Target (at the left of the table) to ensure that the engine
operating point is centred on the site being adjusted.
During initial tuning, if large adjustments are required to a particular site
ensure that the sites around it are also adjusted to a similar value so that the
adjacent sites have minimal influence.
Use the SPACEBAR key to quickly move the adjustment cursor to the
engine,s current operating point.
Site Tables
The RPM and Load sites for the various calibration tables may be modified in
the Setup Sites screen.
A number of site tables are available which affect different calibration tables
Use the help to check which calibration tables are affected by which site
tables.
