I know how to set engine size-B0104. What I am wondering is, What does it affect if it is not set. Let's say you have B0104 set for a 5.0L engine, but the vehicle actually has a 6.0L engine. Would the PCM think that the engine is down on airflow and lean out the mixture? This is probably an irrelevant question----But I am just curious.

I believe, for the purpose of computing airmass, the PCM ignores B0104 and uses the VE/MAF tables.
