56. uction is performed by switching off the ignition or by lowering the advance angle or by switching off the injection This process provides for higher gear shift without clutch and throttling down thus minimizing the time losses during gear shifting The blocking time for individual gears can be set using the software Race tab Reverse polarity of the CLUTCH MASTER switch can be configured using the software Motorbike tab 26 FALL SENSOR One outlet of the Fall sensor will be connected to connector 26 and the other outlet will be connected to SENSE GND 9 or GND 12 13 14 When the Fall sensor is activated the unit will block the ignition with a 1 5 s pause Reverse polarity of the Fall sensor can be configured using the software Motorbike tab The Fall sensor can be activated or deactivated on Motorbike tab Honda motorbikes do not have the Fall sensor included in the unit but the sensor is controlled via power supply relay 27 28 29 30 Ignition coils IC1 IC2 IC3 IC4 Ignition coils outputs are ready for standard types designed for inductive ignition and used on injection type motorbikes primary coil resistance approx 1 to 2 Ohm One outlet of the ignition coil will be connected to key switched 12 V and the other one will be connected to the corresponding connector pin IC1 28 IC2 27 IC3 29 IC4 30 In line engine configuration applies only to motors with cylinder order 4 3 1 2 For double cylinder motors
57. v number number of revs from ignition after which the synchronization condition will be searched b IAP single cylinder allows finding synchronization of the camshaft by analysing pressure changes in the air intake Pressure in selected section during the crankshaft rotation is compared in three consecutive engine revs Parameters to be set Midsection defines whether the section in middle rev will be the longest or the shortest of all three compared Monitored section defines the section to be monitored numbers of lobes Meeting rev defines whether the synchronization condition is met by even or odd rev Source defines the sources of underpressure measurement after the synchronization Whether the source will be intake air underpressure reading input IAP pin 21 or atmospheric pressure reading input AP pin 3 In the case of AP the atmospheric pressure will be measured as well as when AP sensor is missing by IAP reading when the engine is off Min RPM minimum revolution to search for the synchronization condition Min rev number number of revs from ignition after which the synchronization condition will be searched Part 4 Excitation In this part the ignition coil excitation parameters are set For the ignition coils with lower resistance 1 2 ohm the excitation time is usually set to 1500 2000 us for the ignition coils with resistance 2 4 ohm it is usually 2500 4000 microseconds Dynamic excitation component
