LS1 Hotcam Idle Tips Anyone have any tips on getting the hotcam to idle??? I have an A4. I raised the idle control screw... but it will still drop down too far and the car will die.
I havent been able to do the idle relearn procedure yet because I cant get the revs low enough to put it in gear and raise the RPM's to 2000.

Re: LS1 Hotcam Idle Tips I had the same problem when I gad my hotcam installed last year. First I tried raising the idle screw and that helped a little but then I drilled the tb blade to 13/64 which helped a little and then I drilled to 15/64 and that worked for me. Have to give it about a 100 miles or so after you drill the blade to let the car learn the new idle but after the second drill no more car dying in traffic, even with the ac on.
be careful and you'll be fine.

Re: LS1 Hotcam Idle Tips I have been told that messing with the idle screws on A4 cars messes up more stuff than it fixes. It causes the trans to shift inconsistently and also messes with the PCM. I have Ls1edit and have tuned it out plus drilled out the tb hole. Tunning is pretty much manditory for A4 cars with cams.
