I would take a vtec controller over that
also remember, if you do get a vtec controller, to get something that adjusts the air/fuel map along with changing the vtec engagement point, because if vtec is simply engaged at a lower rpm without the extra fuel/air, it will cause some nice damage to your motor----VAFC does this, if tuned properly
