VC2 Map Clamp

[SrtRT]

I just got my VC2 map clamp and I was wondering how to tune it in? I do not have a A/F gauge. I can tune this by using a volt meter correct ? If so what should by voltage be at idle and what should it be at WOT?

Thanks,
Blake

ehhh every car is diffrent so a blanket voltage suggestion will not be exact science by any means. Your best bet is to buy yourself a wideband gauge or if ya want somethign cheaper, buy yourself some dyno tuning.

You can set the voltage, but you'll never know what your F/A is. So get to a dyno and tune it there. The voltage most folks are using with the stock turbo is 4.3-5 volts. With this map clamp, turning the adjustment screw clockwise adds voltage and counter clockwise clamps voltage....

im sorry for asking this but why is a voltage clamp necessary?
