Honda K20X

All this family is supported by VEMS v3 ECU firmware and hardware including VTEC and VVTI control

Note: Hi-side PFET-s come handy, see [v3 ECU product options] when VTEC or VTI control solenoid needs +12V (grounded to engine block).

Trigger specs as follows:

Configlets for this engine are available in VT -> primary trigger -> "4cyl_12+extra_Honda_K20AX_Camsync"

With the information above the setup and installation should be quite straightforward. Spark positions in above triggerlogs might not match real engine (strobe and adjust to correct triggertooth and tdc_delay, when exact info available please take a note here with exact engine code).


F20C 2005 and up is same trigger wheel as k20X but different sensor type is used:

Configlets for this engine are available in VT -> primary trigger -> "4cyl_12+extra_Honda_F20C_05_up_Camsync"


All these engines work (known good, triggers benchtested way above practical max RPM, >14000 RPM)
