Crank reference position

Postby greenamex2 on Mon Apr 22, 2019 8:09 am

Hi

Just confirming to make sure I have read the help correctly.

I am on a 60-2 crank trigger pattern (machined into the flywheel) triggering a hall effect sensor. The leading edge of the first tooth after the gap is at 60 degrees AFTER top dead center.

So, do I enter -60 as the engine speed reference offset, with trigger on rising edge?

Thanks in advance

Thanks for confirming Stephen. Didn't want to spend hours trying to get the engine to start for the first time on a misunderstanding...it's going to be nerve racking enough as it is!
