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 **a** fter 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 ![primary trig](https://europe1.discourse-cdn.com/flex013/uploads/ecumaster/original/2X/d/da4e14576b68457fa6b5cf622e9106ba3d8923be.jpeg) ![Cam trigger scope](https://europe1.discourse-cdn.com/flex013/uploads/ecumaster/original/2X/3/391e57b9a7355d9832ccdae741d8d122fe991781.jpeg) ---

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. ---

I have about same settings 60-2 primary with TDC and secondary at 84° (14 tooth) btdc. My problem is I adjust tooth and angle with ignition locked to 0 degrees and seen 0 degrees with help of light gun. As soon as I lock on 10° i found 20° with light and at locked 20° is actually 30° I use twin coil wasted spark and need sequential injection. ---

So, I got back on this issue and I figured out some details. Cam sync tooth is located 87 tooth after tooth nr #0. If I let the ECU configured only with primary trigger (with cam sync disabled) in the log I get the values CAM sync trigger tooth 87, and CAM1 angle (in degrees) -526 (negative value). I tried to use on secondary trigger “advanced filter” and for trigger tooth I set the value of 26, 86, 87, 60, 120 nothing seems to work. when I enable secondary trigger I only get RPM and no engine start, no sync, in injector pulse and no spark. ---
