Summary of change:
'''Distributor Wiring''' || '''Distributor Pin''' || '''Factory Colour''' || '''Signal''' || || 1 || Black / Lt Green || GND || || 2 || White / Red || +12V || || 3 || White / Brown Spots || Trigger 1 || || 4 || Yellow / Blue || Trigger 2 || '''Triggering problem''' Fero figured out the location of the slots: http://www.vems.hu/files/Fero/Mazda_BP8_CAS.jpg The camwheel rotates counterclockwise. Always say camdegrees when the unit is camdegrees because "degree" is used for crankdegrees. When fed with 12V the trigger2 outputs 5V or 0. Great for the hall trigger setup. Thanks again to Fero. When the crank trigger is hooked up to the board it measures about * 3.8V when light passes through the window * and 150mV when there is an eclipse Double-check polarity ! I am going to be using fully sequential injection so this makes primary and secondary triggers necessary. Config Settings: trigger1, rising,coil,filtering TODO: are you sure about rising edge? '''primary_trigger=07''' trigger2, rising, enabled, filtering TODO: are you sure about rising edge? '''secondary_trigger=05''' not used in coil type triggers '''trigger_tooth=FF''' '''another_trigger_tooth=FF''' '''tooth_wheel=FF''' (*16 usec) x crank_minper value=minimum period in usec Max RPM=8000. So at 8500 RPM, 1crankrot=7ms, 3.5 msec minimum trigger period, 80% of which is: 0xB0 '''crank_minper=B0''' The crank trigger occurs 80 degrees '''before''' TDC. Fero used 0xA2 which is 81 degrees. I assume this value is adjusted and found with a timing light once the engine is running. '''ign_tdcdelay=A0''' This is the default value. Interpolation slope, to determine how much is added on top of the 14V value. '''ign_dwell6=88''' I have no idea what a good ignition crank is for this engine. Fero used 13.25 degrees and so will I for now. '''ign_crank_advance=35''' These are not used for coil setup '''tooth_wheel_twidth1=FF''' '''tooth_wheel_twidth2=FF''' I believe this is how many trigger pulses before the phase is reset. In our case it should be 4 primary pulses for 720 degrees of revolution '''reset_engphase_after=04''' '''TODO''' - need help with this one! rising edge is 18 camdegrees BTDC and falling edge is 57 camdegrees ATDC. The last pulse before TDC occurs a whopping 80 camdegrees before. Can you double-check polarity because it sounds like reversed. I'm uncertain how to turn these details into values. '''cam_sync_f_edge_phase=FF''' '''cam_sync_r_edge_phase=FF''' *WikiAdvert: mailto:michael@fastmail.ca
