I suppose it depends on if faith is being defined as belief in facts or as trust in a person or loyalty to a person. Really, in true faith there are all three aspects. Faith cannot be based only on emotion, for you must know certain facts, that Jesus is the Son of God, that he was crucified, died, was burried, and rose again on the third day. But you also must trust in him, and be loyal to him. So its all involved.
I think, therefore, when people say faith must be logical rather than emotional, they mean faith as regards praxis, as regards belief in how to live, how to worship, how to observe communion, how to "do church," how to baptize, etc.
One big verse cited by those saying this would be Ephesians 4:14 (Although it doesn't actually mention emotions):
That we henceforth be no more children, tossed to and fro, and carried about with every wind of doctrine, by the sleight of men, and cunning craftiness, whereby they lie in wait to deceive;
At this link there is an article replete with verses being used http://www.gospelway.com/bible/emotions.php Some quotes from it:
Romans 10:17 - "Faith comes from hearing and hearing by the Word of God." Faith does not come by feelings or by praying for emotional experiences.
Psalms 119:105 - "God's word is a lamp to our feet and a light to our path." The Bible (not feelings) shows to us the proper way to go. (Cf. Psalm 19:7-11.)
Acts 17:11 - To know whether or not some teaching is true, we should search the Scriptures daily, not pray for an emotional experience.
