Initial Calibration

Before attempting to start the engine the calibration tables should be
initialised to sensible values.

Use the MoTeC ECU Manager software to initialise the ECU calibration tables.

Preferably start with a calibration file from a similar engine as this will make
initial calibration faster and easier.

Clear any *s from the tables by selecting Clear *s from the ECU Manager
software Tools Menu (Press the F9 key). The *s indicate values that have
been set correctly, which is inappropriate at this stage.

Fuel Tables

Fuel - Main Table

Check the Fuel - Main Table.

The table should be smooth.

In general, turbo tables look quite different from throttle position tables, so it is
wise to start with a table from a similar engine.

Fuel - Air Temp

Check the Fuel - Air Temp compensation table.

Typically the following table can be used :

-40 -30 -20 -10 0 10 20 30 40 50 60 70 80+

10 9 8 6 4 2 0 -2 -4 -6 -8 -10 -12

Fuel - Engine Temp

The Fuel - Engine Temp compensation table may be used instead of the cold
start warm up parameter.

If using Engine Temp compensation the following table can be used :

-10 0 10 20 30 40 50 60 70 80 90 100

110+

60 50 40 30 20 10 5 2 0 0 0 0
