I would like to know when and how this is supposed to activate ?. I have a 2004 JDM STI and logging shows it only works at low rpm, engine load, it goes to zero as soon as agressive driving starts and trottle angle goes to about 70 - 80 %.

lol, yea...i wud like to know when the hell does it ever work, i don't feel that it does, and if it does, its not much good compared to other variable valve technologies.....my car has it but i don't feel any difference whether i'm coasting or accelerating hard....in any case, i thought the purpose of this tech was to improve performance for both lo rpm and hi rpm range

When I hit 5,500 the AVCS activates..you'll hear a click ..

Its not as powerful as Vtec doh but you do get some power.

BTW I change my oil to amsoil 10w-40 , this made a hugh difference when AVCS comes in .

if you want to get the job done right and find out the correct details go check the dealer you buy it from.
