DVVT = Dynamic Variable Valve Timing..... basicaly is just meant or design for fuel saving instead like the MMC Mivec or Honda VTEC so call higher power or toque... the diff of the DVVT engine was it was using a timing chain instead of usual of timing belt... hear ppl say tat can save up quite some $$$ cos not need to change timing belt wor... but not confirm bout tat.... although i driving a dvvt engine...

dun flame me if i m wrong.. cheers

So DVVT not for performance. Are there any similarity with Toyota's VVT-i?

well basicaly i hv seen the kembara dvvt fix the safc but the owner has sold off the gadjet due to selling of the car, as for vafc i m not sure bout it will try to check for u guys .. but might need sum time b4 i can really gave a confirm answer..
function of dvvt can b say same as VVT-i kuah... cos born under same mama (toyota own the stakes of daihatsu in japan) if you notice the engine of avanza n kembara r the same engine just diff by the displacement of the engine... this same goes to the myvi...

just for sharing for my experience i hv no problem keeping up wif standard 1.5 vios vvt-i wif my standard dvvt 1.3 on the straight road but due to the weight & staibility of my car was not allow me to going faster.... :P

will try to help out to answer ur question but if i m wrong pls let me know cheers

Nup, you can't use a VAFC on DVVT

unlike Vtec or Mivec which use a push rod mechanism like on and off
DVVT use a variable pulley which change the timing constantly to suit the engine's condition
