EMU Black – 60-2 crank trigger with single-tooth cam trigger, cam phase vs TDC cyl #1

EMU BLACK / CLASSIC
1

Hello,

I’m setting up an EMU Black with a 60-2 primary crank trigger and a single-tooth camshaft trigger for full sync (sequential ignition/injection).

Current setup:

  • Primary trigger: 60-2

  • Trigger angle: 114°

  • Secondary trigger: camshaft, 1 tooth

  • On the trigger scope, the cam pulse appears after crank tooth ~26 (counted from the missing-tooth gap).

My question is:

How should the EMU Black be configured so it correctly understands when the engine is at TDC cylinder #1?
Is there anything else that needs to be set besides trigger angle and cam phase to correctly define TDC cyl #1?

I have a clean trigger scope capture and stable signals.

Thank you

Hi…take ur current setup, crank and check with timing lamp if it is correct.
Maybe u need to invert phase if it only is running in wasted spark mode.

What current setup? tomorrow I will try enable the cam sync in 26 -28 tooth window and see what happens.
