[cfg83]

Hello -

(edited multiple times to get info correct)

I have a question. If you know the following about your car :

1 - Engine displacement in Liters. For example, my engine is 1.9 liters (1901 cc).

2 - Manifold Absolute Pressure (MAP) in inHg (inches Mercury). For example, the value that my engine returns in the OBD II protocol.

3 - Compression Ratio (Optional?) . For example, my car has a compression ratio of 9.5:1.

Question : Can you *calculate* the Manifold Absolute Flow (MAF) in grams per second?

Reason : I ask because I am trying to emulate the published OBD 2007 algorithm

Thank You,
