Triggerlog picture of test on bench confirming good sync-up and spark: 
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
- Primary trigger VR / others Hall
- see InputTrigger/HondaFTwentyTrigger for F20c 2000 to 2005, which is different trigger (12 tooth on crank no extra/missing + 3 cam pulse required for sync all VR crank / cam)
All these engines work (known good, triggers benchtested way above practical max RPM, >14000 RPM)
