Hey , I bought a cable from ebay the J2534 one but i didn't work some issue with the drivers i tried downloading drivers from the xHorse website but i gave up on it, now i heard that USDM and JDM Vitz have interchangeable ECUs so that would mean that their communication standards are identical so i'm banking on that being true.

My running theory as supported by other studies is that increased turbulence increases fuel atomisation leading to a more uniform combustion and flame propagation. Studies i found ran on ethanol or some mixture of ethantol and they showed a 17% increase in power at 3000 ish rpm but tapered off and actually lost power at high rpms since the swirl generator became a disturbance and increased back pressure. They used different designs though, i'm using a tape swirl design
