Summary of change:
The following resources have been obtained while installing VEMS on Toyota 4A-GE 16V & 20V engines. VehicleFitment/Toyota/Injectors VehicleFitment/Toyota/Triggers VehicleFitment/Toyota/Sensors VehicleFitment/Toyota/IdleAirController Toyota 24+4 Trace: http://vems.hu/www.vems.co.uk/VEMSTrigger/Toyota24+4.png Recorded as a Wav file and displayed in Audacity trace. Testing on the bench with: Recorded trigger as a wav works okay, testing distributor driven by a motor works fine. Testing with the trigger in the car through the loom does not give an RPM reading. '''Config & Tables''' http://vems.hu/www.vems.co.uk/VEMSTrigger/config.txt http://vems.hu/www.vems.co.uk/VEMSTrigger/tables.txt '''Connection Details''' The Ne (24tooth) trigger is connected to Trig1, the G1 (4 tooth) trigger is connected to Trig2. The G- combined ground connects to the common grounds. Two 270Ohm resistors pull the signal down to ground. '''Trigger Logs''' Initial test: http://vems.hu/www.vems.co.uk/VEMSTrigger/24+4InCarTrig.txt Test with the Ne and G1 trigger inputs changed over Ge to primary trigger, Ne to secondary trigger - we were out of clues so we thought we'd try it... http://vems.hu/www.vems.co.uk/VEMSTrigger/24+4AfterSwapTrig.txt Changing back to the correct trigger connections but removing the pull-down resistors. http://vems.hu/www.vems.co.uk/VEMSTrigger/24+4FinalMiseryTrig.txt Toyota 24+4 Distributor: http://i81.photobucket.com/albums/j209/JMR_AW11/Ign6.jpg '''#10''' is the injector signal - indicating 1 injection event every two ignition events. Will this work with a divider of 2 to ensure that we get a batch injection event every second ignition event?
