Crank type The rpm signal has to be delivered by an hall inductive sensor using a rotating trigger pattern The individual pattern types are listed under the pulldown menu Not all trigger patterns are compatible with all engine types Possible combinations are listed in this table Some trigger patterns are shown in Appendix 1 Trigger pattern drawings When using a 60 2 trigger pattern the maximum engine speed is limited to 12 500 rpm When using a Hall sensor it is nescessary to use a convertor that will change the Hall signal into an inductive signal exception below The convertor has KMS partnumber 01 01 07 0333 Ref point The reference point the position of the piston at the moment the first tooth after the missing tooth teeth passes the sensor of the crank pickup sensor can be set between 0 and 180 degrees before TDC for most engines recommended between 70 120degree The position of the reference point in the software must be checked Mark the TDC on the crankshaft pulley or flywheel Check with a timing light the degrees when igniting on cylinder 1 in TDC with a static engine speed If the ignition advance set in the software deviates from the measurement with the timing light than you have to correct the reference point in the software TIP set for the complete rpm range the ignition advance map to 10 degrees The ignition advance read out on the software screen will be stable and doesn t change when your engine speed
