My spec:4G93T, standard 0.7 boost, standard mini side mount intercooler...modded: Walbro 255 LPH pump, FSE fuel regulator, 2.5 inch piping, KNN closed pod, megasquirt standalone, removed restrictive air flow sensor.the first dyno i had few weeks back was 195 HP, that's without tuning, and yesterday upon tuning with the megatune connected to the megasquirt at Northern Garage the first run we did the fine tuning on the fuel mapping, managed to hit 200 HP at 6000 rpm, then 2nd run further tuned the ignition timing, only advanced 2 degree from 2K rpm onwards, it's such a magic, managed to hit 211 HP, really happy!Pretty satisfied however i'm worried for the knocking which could happen due to high ignition advance herein, so have i am thinking of doing some own knocking detector device, have u guys ever tried these?http://www.autospeed.com/cms/A_0348/article.htmlhttp://www.autospeed.com/cms/A_0353/article.htmlhttp://www.cs.du.edu/~ljanssen/tr6_turbo.html check out at the knock sensing parthttp://www.honda-tech.com/zerothread?id=1555006&page=1 i'm gonna get myself a HKS EVC in few weeks time to increase the boost level to at least 1 bar, and will further fine tune anything higher than the current 170KPA i have right now, so i need some knocking sensing device......... and wat u guys think? i know HKS is selling them, but that's nothing but just a bunch of electronic stethoscope with HKS names on it!! just need some monitoring device to help monitor the knocking clearly.....</blockquote>
