Call it what you will, Hondas V-tech system is entirely different in every way from the TiVCT system ford uses. Only one fact about them is the same and that is the fact they both use oil pressure to activate the system. Other then that they are polar opposites in how they work and what they affect. I have built more then one of these new 5.0 and a couple Honda motors, I can tell you exactly how each work and what is required for them to make the changes they so in performance and economy.
