Sorry its been so long. So hondata was no help, there answer to everything is that its a socketing problem.i have also tried contacting my tuner, he wont return my messages, so i have decided to start studying and im going to re-tune myself. If thete are any tumers reading this please feel free to give me pointers. I am using the step by step off hondatas website. I have never tuned before so im just goinh to take my time with it, i dont plan on doing it overnight.
there is no way way you can tune it without dyno(you can but it will take you days or weeks to do it and you will need wide band O2 vacuum gauge camera nice stretch of road without cops where you can pull 4th gear from 2000rpm to redline than analyze video comparing rpms with A/F ratio than do the map and repeat this over and over again till you get where you want ) OR
just search around post your car specs exactly what you have till every detail(intake, exhaust, cams, valves spring, C/R... etc) and maybe you will get lucky and someone will have map for you via email and all you have to do is just download it to s300 and yes i now many will say that every car's tune is different and it is, but if you get map from someone one with same boltons that you have map will be somewhere 95% close
so good luck with it
