Now try using the

key. The outlined bar should jump up 0.096 mS. As the bar gets taller,

the fuel delivery is increased and the engine is enriched at that speed and load. Now press the

´

key and the highlighted bar should move down 0.096 mS.

Note that the fuel delivery for the outlined bar is shown in the bottom corner of the display.
Note also that the injection time does not necessarily match the bar height as the injection
time is the actual injection time after various corrections have taken place. Also, the arrow
indicates the bar (i.e. number) currently being accessed by the engine. If the arrow was not
over the highlighted bar this would also cause the bar height and injection time to be different
as the bar height is the height of the bar being adjusted, not necessarily the value of the bar
currently being accessed by the engine. Try using the Control key and the Page Up key

together,

4.6.1 Ignition Setup


The Ignition Setup works in an identical way to the Identification. Its fields are different and
relate to the way the ignition advance is determined for the engine. Enter the Ignition Setup

by pressing

. The fields in the Ignition Setup for Basic Mode are:


Trigger Degrees : This field tells the ECU where to expect the Main Trigger to occur. This

field is very important for the correct operation of the ignition. If it is incorrect, the
spark advance will also be incorrect, which could lead to engine damage. The ECU
needs to receive an input trigger at a fixed engine angle Before Top Dead Center
(BTDC) for each spark. This trigger may be set between 60° and 100° BTDC. See
Chapter 5 [5.2-3] for detail on how to check the timing and this field.


Lock Timing at 10 Degrees: This field is used for testing the trigger input. It allows the

timing to be locked at ten degrees regardless of the engine speed and ignores the
ignition map settings. This feature is further discussed in Appendix E
