vtec controller

i just purchased a vtec controller and it is sick, but guess what, it doesnt come with instructions. it is a APEX vafc and i was wondering if any of you had the sam problems adn didnt know how to program it quite right. is it possible to make vtec kick in earlier, i have heard some say yes and some say no.
