Hey Guys.

Just a quick question, i quickly flicked through some of the course and on the module about triggers ryan spoke briefly about ref and sync.

My question is which is cam and which is crank angle sensor as i'm still a little unsure. I've always known them as just cam and crank angle sensors and is ref the same as trigger when talking about trigger and sync ?

any help would be great guys !


REF - is your crank

SYNC - is your cam

I just remembered it as the crank being a 'reference' point to tuning the engine position

Thanks Ryan, that's a big help mate
