cam trigger problem


Recommended Posts

hello im running sequential injection direct spark so i belive i need to set trigger 2 to cam pulse x1. 

only problem if i set this setting to anything other than none it wont start and has no rpm signal but as its set to none the engine doesnt know where it is so it either starts or backfires.

is there any other settings related to triggers.

trigger status only goes to green and yes if trigger 2 is set to none 

the cam has 2 pickups 90 degrees apart and the crank is 36-1 one the engine starts it runs fine .

cosworth yb engine

How low can you go on trigger arming threshold on 0 mines set to 0.5 and 1000 is set to 1.0.

 reason i ask is wen i set sync mode to none i get revs but no trigger 2 signal untill the car starts the once its running get no trigger errors and it doesnt drop out. so at a guess when i set it to cam pulse 1 the lower end setting wont read the cam sensor so it wont sync up and start.

on cam pulse will it only see revs once the triggers are in sync

Lowest is 0.2 

Best bet will be to scope the signal to get the actual voltage and would also confirm the polarity is correct. If you keep the sensor to tooth gap as close as possible this will help keep the voltage up.

had a quick play i lowered 0 to 0.2 and 1000 to 0.5 and bingo it found trigger two on cranking.

i have also got hold of a oscilloscope only problem is i dont know how to use it and the person i lent it off doesnt know how it works  either its over 5 years old and still in the box its never been used
