Default irratic idle after vig 3200 install

does a converter have anything to do with my car idling WAY low? After installing my vig 3200 the car doesn't idle hugh enough.

can I adjust something mechanically to idle higher?

or will it need programming?

You can raise the idle by tightening up the idle screw on the TB. I think it needs either a 20 or 15mm torx bit. Do you have a-tap or a scanmaster to check the tps voltage? Stock tps is .46 I believe. You could also drill the hole in the TB up one size, but I think the idle screw is a better place to start.

When I first installed my Vig2800 I had the same problem. After a few days it returned back to normal. I think it does this because you have changes the amount rotating mass the engine has to turn. If I am incorrect someone please correct me.

Could be.. haven't had that problem with any of the converter installs I've done.

Did you disconnect the battery during install? Could be the computer "re-learning".

You could try the idle relearn. That picked up my idle after the ST3500 install, but it never got rid of the surging. If my car idles in gear for a while at a drive through or such the idle will vary about 100 rpms almost rythmically up and down.

its just the smaller size of the converter i believe.. mine surges from time to time...

yes in park or neutral it is fine but in gear it does the 100 or so rpm up and down thing. Would turning that idle screw help?

wouldn't turning the screw make it too high in park or neutral???

I have no scanmaster or auto tap, is the scanmaster worth getting? (Still have no way of tuning it myself) with ls1 edit you can tune yourself but also need a laptop right?
