The ignition pulse sensor (ISU) is connected in series between the ignition output of the first cylinder and the primary side of the ignition coil of the first cylinder. The ignition impulse of the first cylinder is transmitted in firing order to the DetCon ignition input.
The jumper with the designation Load Resistance has not be removed.
Position Load Resistance jumper The jumper Load Resistance changes the input resistance of the ignition input.
It is on the upper left of the device |
If not all cylinders are fitted with detonation sensors, the ignition sensor unit is installed on the cylinder on which the first detonation sensor is installed.
