trigger log need your opinions and suggestions .....
« on: May 05, 2011, 02:07:29 pm »
Hi everybody,
I'm back with a brand new upgraded 3.3 board :D
I've made some trigger test because I want to run with the secondary trigger (inlet cam,hall type).
Can you take a look on this trigger log and give me your opinion:

I don't understand what you're asking. What I see are too many cam pulses, you need one every two crank rotations. What do you need to know?

Probably you should cut three teeth on cam trigger.

In fact what I wanted to know if this signal was correct or do I have to modify the "wheel" and how....
Here is the pic of the "secondary trigger wheel":

Do I have to use the first signal after the primary trigger missing tooth or the second ?
Why the teeth are so different ?do I have to keep only one small teeth or a large one?
Do this kind of wheel work on rising or falling ?
If I understand I need only 1 trigger cam for 2 crank revolution?

Try to log with opposite edge than before (falling/rising).

 In new firmwares (not officially released jet) we have possibility to allow ECU to see signals just configurabe amount of teeth after the missing gap. But of course signal should be asymmetrical between two cycles.

In other words,in the 1.1.90 is it  possible to choose the needed signal if we have more than one like mine?
Where and how can I get this last firmware ?I've tried with the VemsTune firmware tool with no success....

You mean in triggerlog? Strange: if you have falling there must be rising..
