4.8 Driver on Coil Logic Driven Coils
If you select Driver on Coil logic driven coils you will not use the shielded wires found on
pins [1,2,3,4 and 13,14,15,16]. Remove or tape these wires off. The DOC logic level outputs are
very sensitive to miss wiring. Be careful not to short these wires to ground or +12V. Internal
damage will happen if you do. The DOC logic outputs are +5 volt logic and cannot drive coils
directly. It is allowed to connect up to two DOC coils to each logic output.
DOC coils either are 3 or 4 wire devices.

The wiring of the logic signals simply follows the plug wiring as noted in the standard DFU
wiring above. Where a coil spark plug wire connection is indicated substitute the DOC logic
output for that cylinders DOC coil. One DOC logic output is wired to two DOC coils.

When using the DOC logic outputs, tape up or remove the unused standard coil outputs.
WARNING: Before starting the engine when DOC coils are used, change the engine
configuration setting to DOC coil and set a fixed dwell time. If you do not know the exact dwell
time to use for the coil you have, start with 1.8 mSec. Failure to make this calibration change
may cause extreme damage to the coils.
