can someone exlpain to me about what the V/T Unmatch fuel correction means exactly... in the V-AFC instructions i doesn't make any sense to me:

Hi<<L: this is when the VAFC turns the VTEC hi (on) but the ECU sets the VTEC Lo (off) (The engine will actually be set to the Hi cam.)

Lo<<H: this is when the VAFC turns the VTEC Lo (off) but the ECU sets the VTEC HI (on) (The engine will actually be set to the Lo cam.)

thats what the instructions say but its making no sense to me at this point... can someone explain to me what that actually means in easier terms?????
