Firing angle calculations, Manual TDC angles.

0-720 degrees (full engine cycle in 4-stroke mode).

Cylinder 1 should always be 0.

Each cylinders TDC needs to be unique and in ascending order.


Firing angle calculations, Automatic TDC angles.

Used on "Even" fire engines. Firing angles are calculated in MaxxECU and no need for user inputs.



60degree V6 (even fire):

Event 1: 0

Event 2: 120

Event 3: 240

Event 4: 360

Event 5: 480
