Clint a Posted November 25, 2018 Report Share Posted November 25, 2018 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 !

Adamw Posted November 25, 2018 Report Share Posted November 25, 2018 Your basic settings look alright. Does it show stable and realistic RPM in the software when you are cranking? If not, my first suspicion would be the arming thresholds are too high - the Toyota dizzys put out quite low voltage at cranking speeds. So I would put 0.2V in the 0RPM cell and 0.5V in the 1000RPM cell in both trig 1 & 2 arming threshold tables. Quote Link to comment Share on other sites More sharing options...
