Subject: Survey of Ignition Systems - Basic
Ignition Adjustment
Vehicles: All Models
This
Technical Information Bulletin gives a survey of all ignition systems installed
as of Model Year 1989 and their adjustment. The operating instructions and
notes are generally valid and cover all previous adjustment instructions.
In
the past, varying adjustment procedures have repeatedly been the cause of wrong
adjustments.
For
this reason the following operating instructions and notes must be carefully
observed so that a m correct basic ignition adjustment is guaranteed.
Important Workshop Notes
Important
Electronic ignition systems
have a higher ignition capacity than those used up to now.
Because of this, it is
dangerous to touch voltage-bearing parts - low tension as well as high tension.
When working on the ignition
system it must always be switched off or the battery disconnected.
Such operations are, for
example: changing parts such as spark plugs, ignition coil, distributor, ignition
leads or trigger box. The same safety precautions apply when connecting
checking equipment such as ignition timing light, dwell angle engine speed
tester, ignition oscillograph, etc.
They must not be connected
unless the ignition system is switched off.

* Engine speed (A)
represents only a range of validity where the basic adjustment is carried
out.
|
|
Furthermore,
idle speed and idle speed CO must be checked and if necessary adjusted after
the
|
|
basic
ignition adjustment has been carried out.
|
|
|
|
Basic Ignition Adjustment
for CI and TI-i
* Engine must be at operating temperature (oil ³ 80 °C/176 °F).
* Engine off.
* Remove vacuum line from vacuum advance/retard
unit.
* Start engine.
* Engine speed between 700
min-1 and 1000 min-1
* Firing angle must have value B according to table
(Opel Tester) or the marking on the pulley, and the pin on the oil pump
housing or cogged belt cover must align (timing light). -see illustration A
7895-
* If necessary, correct the basic adjustment by turning
the distributor.
* Reconnect vacuum line.
|
|
|
Important:
The pulley on 1.4 Ltr.
engines has two markings.
1.4 Ltr. engines are
adjusted by turning in the direction of the 2nd marking (5°). -see illustration C 9810-
|
|
|
Basic Ignition Adjustment
MSTS-i (Multec)
* Engine must be at operating temperature (oil ³ 80 °C/176 °F).
* Engine speed between 700
min-1 and 1000 min-1.
* Remove protective cap. (As
of MY 87)
* On vehicles up to Model Year 86 pin A and B in the
diagnostic plug are to be bridged with KM-602-2. -see illustration C 2373-
* On vehicles as of Model Year 87 the basic
ignition adjustment is possible with KM-640 in position "B" as
well as with TECH 1 and
Program
Module OPEL 86-87 ECU Mode F1
Program
Module OPEL 87-88 ECUMode F5 Program Module OPEL 88-89 ECU Mode.
-see
illustration C 5608-
|
|
|
* Firing angle must have value B according to table
(Opel Tester) or the marking on the pulley and the pin on the oil pump
housing or cogged belt cover must align (timing light).
* If necessary correct the basic adjustment by
turning the distributor.
* Disconnect bridge.
* Replace protective cap.
|
|
|
Basic Ignition Adjustment
for MSTS-i and (MZV)
* Engine must be at operating temperature (oil ³ 80 °C/176 °F).
* Disconnect coding plug.
Illustration
D 1250 shows installation position in the Kadett-E/Astra/ Belmont. In this
case, the plug is located in the bulkhead area.
Note:
The
coding plug may be removed only when the engine speed exceeds 600 min-1.
* Engine speed between 700
min-1 and 1000 min-1.
|
|
|
* Firing angle must have value B according to table
(Opel Tester) or the marking on the pulley, and the pin on the oil pump
housing or cogged belt cover must align (timing light). -see illustration B
5575-
* If necessary correct the basic adjustment by turning
the distributor.
* Engine off.
* Reconnect coding plug.
|
|
|
Basic Ignition Adjustment
for EAI-h (EI 10) and MSTS-h (EI 11)
* Engine must be at operating temperature (oil ³ 80 °C/176 °F).
* Engine off.
* Remove vacuum hose from vacuum advance/retard unit
(if present).
* Disconnect plug from throttle valve switch and
bridge all three contacts in the plug. -see illustration B 8656-
* Start engine.
* Engine speed between 700
min-1 and 1000 min-1.
|
|
|
* Firing angle must have value B according to the
table (Opel Tester) or the marking on the pulley, and the pin on the oil pump
housing or cogged belt cover must align (timing light). -see illustration C
3639-
* If necessary correct the basic adjustment by
turning the distributor.
* Open bridge in plug and connect plug to throttle
valve switch.
Important:
On
vehicles with electronic 4-speed AT, trouble codes are to be deleted after
the basic ignition adjustment.

Basic Ignition Adjustment
for MSTS-i (EI 61)
Basic ignition adjustment is
neither possible nor necessary since the crankshaft triggering guarantees a
pre-set signal sequence.
Checking the Ignition
* Engine must be at operating temperature (oil ³ 80 °C/176 °F).
* Engine off
* Carburettor Engine
Disconnect
vacuum hose from control unit
* Injection Engine
Disconnect
plug from throttle valve switch and bridge pins 18, 3, and 2.
|
|
|
* Start engine.
* At engine speed A, firing angle must have value B
according to the table.
* Reconnect vacuum hose to control unit or open plug
bridge and reconnect plug to throttle valve switch.
Note:
The
values in the table are valid for RON 98 coding
|
|
|
Basic Ignition Adjustment
for MSTS-h (EI Plus)
* Engine must be at operating temperature (oil ³ 80 °C/176 °F).
* Engine off.
* Disconnect coding plug.
Illustration
C 9068 shows installation position in the Vectra/Cavalier. In the
Kadett-E/Astra/Belmont the plug is located in the bulkhead area.
* Start engine.
* Engine speed between 700
min-1 and 1000 min-1.
|
|
|
* Firing angle must have value B according to the
table (Opel Tester), or the marking on the pulley and the pin on the oil pump
housing or cogged belt cover must align. -see illustration B 5575-
* If necessary correct the basic adjustment by
turning the distributor.
* Turn off engine and
reconnect coding plug.
Note:
Basic
adjustment is possible also with TECH 1 and Program Module OPEL 88-89 ECU in
mode F5. See Checking Procedures MSTS with Self-diagnosis (EI Plus). TSD No.:
1551-E dated 11/88
Time
Allowance:
The
time allowance for the operation "Ignition - Adjust" is to be taken
from the appropriate time allowance microfiche.
