The cam rotates at half the speed of the crank. So with a cam mounted 24 teeth trigger wheel, If your are using "crank speed" reference in TS then it's 12 teeth, "cam speed" then it's 24 teeth. So essentially with 1 rotation of the crank you are telling speeduino that it would see 12 teeth. A complete cycle is 720° so 2 crank revolutions 12x2 teeth = 24. Hence why we can remove 1 tooth from the 24 tooth wheel in the distributor and be able to run full sequential.george-angelosvoudouris wrote: ↑Sat Apr 11, 2020 4:15 pm@evo_lucian oh I forgot about the trigger teeth 24 if the sensor is on crank 12 if on cam correct? Thanks for the tips I'll check them one by one!
I decided to check the distributor signals on the bench for the factory distributor! So speedy on the bench a second distributor I had laying around hand drill and off we go!
I noticed 2 things.... on low RPM (cranking) I get to many trigger signals on higher RPM the signal starts to clear up!
The second thing is that as I stopped the drill and came at a full stop I saw all the ignition LEDs come on and then they stoped!
i have attached a composite logger file if someone likes to take a look
Which trigger were you using for your bench test, 24/1 or basic distributor?
