  1. Hi team, Im a Complete newbe to ecus and am having issues calibrating the trigger set up and base timing with my atom , if anyone could shed some light in my situation it would be much appreciated as I’m trying to get it to start and idle prior to sending it a tuner as I don’t have deep pockets im running a 3sge “non beams” gen 3 from a st202 Celica on 4age itb’s with a bunch of gen 2 parts to enable easy mounting in red format , To complicate things I’m running cop from a cr14 Nissan march via the original distributor. Current timing mark is 0 tbc Wired as Wire description Loom to ECU Colour code Installation connection Trigger 1 Black CAS crank Trigger 2 Red CAS cam Analogue temp input 1 Yellow Water temp Analogue temp input 2 Yellow / Brown Air Intake temp Analogue volt 1 Yellow / Blue MAP pin 2 Analogue volt 2 White / Brown Analogue volt 3 Yellow / Black TPS pin2 +5v out Red / Blue TPS / MAP Ignition 1 Brown / Black COP 1 pin3 Ignition 2 Brown COP 2 pin 3 Ignition 3 Brown / Red COP 3 pin 3 Ignition 4 Brown / Orange COP 4 pin 3 Injection 1 Blue Injector 1 Injection 2 Blue / Brown Injector 2 Injection 3 Blue / Red Injector 3 Injection 4 Blue / Orange Injector 4 Auxiliary output 1 Orange / Black ICSV Auxiliary output 2 Orange / Brown Fan relay coil Auxiliary output 3 Orange / Red Fuel pump relay coil Auxiliary output 4 Orange Tachometer Digital input 1 Grey / Black Digital input 2 Grey / Brown I’ve tested the cops individually and confirmed they work Trigger 1 configuration trigger 1 type = reluctor trigger 1 filtering = level 1 (low) muti-tooth posn = cam tooth count = 24 trigger arming threshold table .0 1k 2k 3k 4K 5k 6k 0.5 2.0 3.0 3.5 3.5 3.5 3.5 trigger 2 configuration trigger 2 type = reluctor Trigger 2 type filtering = level 2 filtering sync mode = cam pulse x1 trigger arming threshold table .0 1k 2k 3k 4K 5k 6k 0.5. 2.0. 3.0. 3.5. 3.5. 3.5. 3.5. The issue I have is as follows I’ve set up a little ht lead between my cop and spark plug on cylinder 1 when I go into triggers calibrate with fuel turned off and try to set base timing and crank it I’m not getting a spark every revolution so can’t set / adjust the timing what on earth have I done wrong or have I missed , I’m sure it obvious to people with knowledge but I’m stumped ! Regards Clint
