I have been installing my Crower Stage 2 cam, and I have been told that it runs super rich at idle. I have a VAFC, now how do I lean it out at idle so it's good to drive until I get to a dyno? Thanks!

your car probably idles around <800> take out fuel at the 1k mark, play around with the vafc until you notice a difference, it will be impossible to know a/f without a wideband but it wouldn't hurt since you plan on dynoing soon....

Which setting is that though? Narrow throttle? Please give me more steps, I am new with the VAFC.

take the fuel down till it starts to idle funny, then put it up a few settings. Really though, a dyno is the only way to get it right. Also I don't know the settings.

Go to "narrow throttle," and "arrow" to the left until you hit 1000rpm. "Arrow" down, and you'll see the numbers start dipping into the negatives, which is a percentage of fuel you're removing. The idle will start to change, adjust accordingly.

1000 RPM low throttle setting.

thanks guys, now until I get it tuned, will it run ok? (eventhough the car wont even start currently because of my new damn vavletrain). But thanks!
