。
remove sparkplug from cylinder head and mount dial gauge in cylinder.
。
find TDC (Top Dead Centre)
。
rotate engine backwards (opposite from running engine rotation) to calculated advance
in millimetres (in example above it is 1,3 mm) and make marks on rotor and stator
。
remove dial gauge and install sparkplug back in cylinder head
。
start engine and run at constant speed of 3000 rpm to 4000 rpm
。
use a strobe light to check alignment of marks on rotor and stator
。
adjust static angle with programmer to align marks on the rotor and stator
Result of above procedure is very accurate static angle.
Important!
。
Static angle is reference point for CDI to calculate delay for programmed ignition
advance.
。
Static angle has to be greater then maximum ignition advance!
。
Example - If maximum advance in ignition map is 30 deg, then static angle has to
be at least 31 deg.
。
Very large static angles are not a good solution, because it decreases
electronic ignition advance stability (do not use static angle greater then 45 deg if not necessary).
If you find when testing with your strobe light that your timing marks are off by 10, or more
degrees it may be neccessary to reverse the wiring from the reluctor pickup to the ignition and test
again. Reluctor pickups have polarity but it is rarely marked on the pickups so must be determined
by the trial and error method. Incorrect wiring polarity will cause the reluctor pickup to send the
trigger signal on the trailing edge of the rotor instead of the required leading edge of the rotor.

MONITORING
Connect
programmer
to
PDCI
and wait few seconds for activation of
programmer.
Fist
information displayed on the
programmer
is firmware version.
With
programmer
you can watch revs, calculated advance ignition angle, selected ignition curve,
TPS position...depends on setting in the menu.
Information!
You can connect, or disconnect
PDCI
unit from
programmer
any time you want without any
harm. It is not important, if motor running, or not and if power supply is connected, or not.
Important!
Do not use too much force when connecting, or disconnecting
programmer
unit!
