why not? any chip mugen, spoon, ect are made to alter the fuel/air curve and tune the engine to a more sportier running condition. like lower the vtec engagement point. if im correct (correct me if im wrong) you can use the v fac to alter the vtec and fuel/air intake and lower the vtec engagement. you can monitor it more closely since it has a screen. if anyone knows more than what i do, please correct me
