Does the HX setup run on 2 valves before vtec is activated and once it kicks in then it works on 4 valves or the other way around? If it works on once vtec hit it opens 4 valves how can I make it constantly keep it in vtec? I'm asking this since I don't wanna use the HX ecu cause that ---- is rocket science within itself and plus I'd have to switch over to OBD2 which I'd never do just to use that shitty ecu. I was thinking of using uberdata to operate this head and make it run properly without using that ecu. help anyone? I wanna try use this head out on my 1.5 NA setup I'm building.

 

I believe its 3 stage VTEC-E so there is a step when it uses all 4 vavles and also a step when it used the normal vtec.
