Summary of change:
Project: VEMS controlled ignition and injection on Subaru Libero with 3 throttle bodies and injectors from motorcycle (Suzuki) Engine inline 3 cylinder 1189ccm (used in Subaru Libero or Justy) engine code: EF12 * '''4 stroke''' * max RPM: 7000 /min * '''firing order: 1-3-2''' * firing step: every 120° of crank (of course) * firing step between 2 cylinders: 240° of crank So you mean that firing (relative to cyl1) * '''cyl1''' is 0, 360 crankdeg * cyl3 is 120, 480 crankdeg * cyl2 is 240, 600 crankdeg ---- Actuators: IGN.coils: '''3pcs of automotive ign. coils (Marelli).''' * '''passive coils for wasted spark applications''' ** every coil will fire just one time per revolution of crank as always on wastedspark coils '''INJECTORS: 3pcs of 15 Ohm motorcycle injectors''' (first time customer measure it incorrect :) they are 15 Ohm suzuki hayabusa 1300 k7 injectors and not 130 Ohm like customer says) Sorry for desinformation. Idle valve: maybe PWM, bi-metal or none ---- '''Sensors''' * TPS: classic * CLT: classic NTC * MAT: classic NTC * WBO2: LSU 4.2 or 4.9 ---- '''Trigger1: 60-2 (VR type)''' '''Trigger2:''' i do not want to use '''trigger2''' (But the OEM distributor have 4 teeth and '''VR sensor'''. 3 teeth are at 120° and one tooth is approx 10° before the another one (for first cylinder, "Honda extratooth style") 1. Could i drive IGN and INJ with just Trigger1? My opinion is, that it '''will work "like wasted spark"''', on crank will be 3 ign. points, every 120°, it means 6 ign. points every 2 revolutions of crank. Is it possible to set this in VEMS with only Trigger1? Should be no problem (as you say, simple wasted spark setup) assuming 120 degree "even firing" of: cyl 1, 3, 2, 1, 3, 2 ---- '''ECU configuration:''' IGN drivers: 4x IGBT + 4x digital INJ drivers: High-Z 30V flyback Trigger 1: VR Trigger 2: HALL EGT input: no ETC: no 1-wire: no Hi-side PFET: no Knock channel: no LCD: no MAP: external (we'll just use Alpha-N strategy because of separated throttle bodies) SD-Card: no Flanged case: yes
Optional: Add document to category:
Wiki formatting: * is Bullet list ** Bullet list subentry ... '''Bold''', ---- is horizontal ruler, <code> preformatted text... </code> See wiki editing HELP for tables and other formatting tips and tricks.
