just dont use it yet.
the best settings after installing a VAFC when you have a stock motor and NO dyno are NO change in settings at all. screw balling around with the VAFC without proper knowledge of how to tune it, ESPECIALLY without a dyno, will only cause you problems and will eventually end in engine damage. dont even hook the VAFC up yet (althought you already have) if you dont have the $$$ to get it properly dyno tuned or there is no dyno in your area available at this point in time...im not talking smack here, im just trying to help you out because you/whoever you let touch your VAFC will do damage to your engine by "tinkering" with the settings using guess-work or settings that worked on OTHER peoples setups. never use settings that other people have programmed in on their setups because every motor is different, due to mileage/wear and tear/different mods, etc. etc... i just dont want to hear about you/anyone else doing damage to your ride due to insufficient knowledge or funding because that would be a shame. just take your time with it, if need be you should unplug the vafc from your ecu until you can have it properly dyno tuned. i know the little blue display box on your dash probably looks pretty when it lights up at night and impresses all your friends, but are they still gonna be impressed when your motor blows from having it tuned uncorrectly.
(i know you werent asking for all this, but this question has come up numerous times here in the Si/SiR forum and should be made a "sticky" if enough info can be grabbed about the subject. you'd be surprised as to how many people actually do buy a vafc thinking they will see mega power gains just by plugging it in- like i said before, it will hurt much more then it can help without proper tuning...good luck)
