max Posted September 8, 2018 Report Share Posted September 8, 2018 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 Quote Link to comment Share on other sites More sharing options...
Simon Posted September 11, 2018 Report Share Posted September 11, 2018 The correct option where the stock crank trigger has been changed is to remove one of the cam teeth to leave only one. You will then be able to use the trig 2 set as Cam x1 Quote Link to comment Share on other sites More sharing options...
max Posted September 11, 2018 Author Report Share Posted September 11, 2018 ok i will cut one lug off does it matter what degree the remaining one reads Quote Link to comment Share on other sites More sharing options...
Simon Posted September 11, 2018 Report Share Posted September 11, 2018 No either will be fine. If one is happening close to when the gap goes past the crank sensor this would be the best one to remove. Quote Link to comment Share on other sites More sharing options...
max Posted September 11, 2018 Author Report Share Posted September 11, 2018 ok its mounted on the end of the cam so if it clashes i can move it Quote Link to comment Share on other sites More sharing options...
max Posted September 12, 2018 Author Report Share Posted September 12, 2018 cut a lug off now it's worse than ever takes even longer to start and still no trigger 2 signal or rpm with cam pulse 1 selected will still only start on setting non then it finds trigger 2 and get revs Quote Link to comment Share on other sites More sharing options...
max Posted September 12, 2018 Author Report Share Posted September 12, 2018 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 Quote Link to comment Share on other sites More sharing options...
Simon Posted September 13, 2018 Report Share Posted September 13, 2018 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. Quote Link to comment Share on other sites More sharing options...
max Posted September 13, 2018 Author Report Share Posted September 13, 2018 Will have to try and get hold of a scope Quote Link to comment Share on other sites More sharing options...
max Posted September 13, 2018 Author Report Share Posted September 13, 2018 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 Quote Link to comment Share on other sites More sharing options...
