Manufacturer Applications
13 1. Ignition angle retardation - cylinder 1 (retardation by knock control,
active across complete engine speed range from a minimum
engine load of 3 ms).
2. Ignition angle retardation - cylinder 2 (retardation by knock control,
active across complete engine speed range from a minimum
engine load of 3 ms).
3. Ignition angle retardation - cylinder 3 (retardation by knock control,
active across complete engine speed range from a minimum
engine load of 3 ms).
4. Ignition angle retardation - cylinder 4 (retardation by knock control,
active across complete engine speed range from a minimum
engine load of 3 ms).
14 1. Engine speed (Read-out in steps of 40 rpm).
2. Engine load (injection time per revolution).
3. Ignition angle retardation - cylinder1 (retardation by knock control,
active across complete engine speed range from a minimum
engine load of 3 ms).
4. Ignition angle retardation - cylinder2 (retardation by knock control,
active across complete engine speed range from a minimum
engine load of 3 ms).
15 1. Engine speed (read-out in steps of 40 rpm).
2. Engine load (injection time per revolution).
3. Ignition angle retardation - cylinder 3 (retardation by knock control,
active across complete engine speed range from a minimum
engine load of 3 ms).
4. Ignition angle retardation - cylinder 4 (retardation by knock control,
active across complete engine speed range from a minimum
engine load of 3 ms).
16 1. Knock sensor signal - cylinder 1 (at idle; at high engine speeds, the
signal voltage may achieve values up to 5.1 V).
2. Knock sensor signal - cylinder 2 (at idle; at high engine speeds, the
signal voltage may achieve values up to 5.1 V).
3. Knock sensor signal - cylinder 3 (at idle; at high engine speeds, the
signal voltage may achieve values up to 5.1 V).
4. Knock sensor signal - cylinder 4 (at idle; at high engine speeds, the
signal voltage may achieve values up to 5.1 V).
17 1. Engine speed (read-out in steps of 40 rpm. Specified as 820 to 900
rpm for ADP engine code).
2. Engine load (injection time per revolution. Specified as 1.0 to 2.5
ms for ADP engine code).
3. Read out dependent of engine code (see note below).
4. Ignition angle (specified at 12° CA for ADP engine).
NOTE: Distributor basic setting, for engine code ADP only:- the Hall sender signal
position is set by turning the distributor, whilst the Modernity unit can process the signal
within the range specified - maintain a range of -3 to 3° CA when setting. Energy
balance for Cat heating, for engine code ADR only:- for rapid heating of the catalytic
converter (when operating temp. is reached the energy balance will read 1or above).
