4.6.1 EPT Tab
EPT_Type
Tip Strip: Selects pattern type for the EPT function
Detail: EPT function selection for pattern type and extrapolation level. Some pattern type selections only
support one level of extrapolation due to the typical number of crank teeth for that pattern type. Refer to
tables 4.6.a and 4.6.b in the Engine Position Tracking Setup window section for pattern support details.
EPT ENC 2:
Supports encoder pattern types and extrapolates to 2^2=4 Crank Angle Ticks (CAT) between
each crank tooth.
EPT ENC 4: Supports encoder pattern types and extrapolates to 2^4=16 CAT between each crank tooth.
EPT N-M 7: Supports N-M pattern types and extrapolates to 2^7=128 CAT between each crank tooth. M can
be one or two missing adjacent teeth.
EPT N+1 9:
Supports N+1 pattern types and extrapolates to 2^9=512 CAT between each crank tooth.
