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

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 !
