Visit Preferences to set your user name Summary of change: '''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 [http://shop.vems.hu/catalog/vems-p-48.html v3 ECU product options] when VTEC or VTI control solenoid needs +12V (grounded to engine block). Trigger specs as follows: * Trigger settings for, [http://www.k20a.org/forum/showthread.php?t=85125 12+1extrapulse crank 4+extrapulse on cam] 4cyl Honda K20A engine camsync * Primary trigger HALL * Secondary trigger HALL: Exhaust(4+1) needed for cam sync * 3d trigger HALL: intake(4pulses), needed for campos for intake cam * the 4 active coils work with logiclevel output 0/5V with standard 255 Ohm (or even with 510 ohm) series resistors.

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: * Primary trigger VR * Secondary trigger HALL: Exhaust(4+1) needed for cam sync 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) * 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) Optional: Add document to category: Wiki formatting: * is Bullet list ** Bullet list subentry ...
