cam sync rule....is this true?

[krzak]

Hello
I installing vems in 4cyl car with 2 long teeth on crank and 1 tooth on cam.
I have no spark

I use FW 1.1.18

I heard rule about cam sync "The only rule is that you can't have a second trigger pulse at the same time as a crank trigger pulse"

Is this true?

What with new FW ie.1.1.70?
I always must use this rule to cam sync?
When it will be change?

Thx for learn

Yes its true.

Can you change the sync trigger to falling edge?

Please tell me what firmware will be ok for this pattern 2crank 1cam.
Thx a lot.

This config uses the same trigger setup, and runs. Right now I recommend firmware 1.1.74.
