Thread: Change Engine Displacement?

    Change Engine Displacement?

    I'm making some changes to my tune for a new engine build I'm working on. I am increasing the displacement of the engine. Under "engine displacement" I see a value of 0.00155 lb. I have no idea what this value means or how to change it accordingly. This is on a fresh V2.25 install as of today, so it should be a current build of VCM.

    What does 0.00155 lb mean?

    Thanks

    It represents cylinder air mass at a certain pressure and temp. Multiply it by the percentage you changed it from stock to your current engine.
