Both the FSM and the MP Magnum Engine book say that turning the distributor
adjusts only when the injectors open and do not adjust ignition timing.
A scanner with the capability to do the Set Synchronization Mode test
is needed. Bring up the test on the scanner with engine running and
adjust the distributor (very small amount of turning is required), if needed,
while reading the display. On the OTC scanner, it shows:
SYNC TEST ACTIVE
Adjust sensor to 0 degrees
Sensor setting = xx
(Sync in Range) or (Sync Not in Range)
IMPORTANT: Do not press the accelerator during this reset mode: this will
stop the synchronization process. Restart the synchronization
process if necessary.
Once the synch has been reset to 0 degrees, the PCM will readjust the setting
to the optimum setting.
I don't really know what the Alldata CD is referring to when it says to use
a timing light.
