How to check the Engine Speed Reference Offset (CRiP) in a Modern MoTeC M1 Engine Management System using a Timing Light and marks on the engine representing Top Dead Center #1 Cylinder Compression.
I was just explaining this to a friend in Arizona. Always verify with a light. The commanded advance doesn’t always match real life. Don’t just trust a tune or settings someone gave you. 5 degrees off can spell disaster at 200kpa or more.
