Hall Distributor with different window sizes - will it work?

I´m using my original distributor to get the RPM signal to my MS.

But as my original fuel injection is sequential, the first window of the distributor gives a pulse 3 degrees larger than the others.

Will I have any problem with this issue?

I think it could depend on whether the 3° is at the start or end of the window. If the window is longer at the end then it may work. I assume you're using it where the start of the window is for running timing and the end of the window is used for cranking trigger return. If so, it will probably work okay, but your cranking may be a bit funny.

If it is longer at both ends then no - but you could make the other windows the same to use it. If it is longer at the beginning of the opening then you can make the other windows the same or you might be able to invert the signal to use it as-is, but then you'll also have to rephase your distributor 90°

Does that help?
