Hello frinds

Do I need the cam signal in sumi sequantiol & waste spark wiring?

The engine is BMW m50b25 non vanos

If you are happy to run semi sequential and they are fixed cams you can run off the crank signal alone.

You will have a slightly higher controlable power limit if you are pushing the limit of your injectors if you do run a cam signal, likewise if you run very large injectors idle and cruise will be easier to tune full sequential.
