Idle tuning with a large cam
Hello everyone. I am trying to get my Cavalier to idle decently with my tune. I have a 2001 Cavalier with 2200 turbo setup.
The problem I am having, is that with my cam, I see around 1/2 the vacuum at idle that I used to with the stock cam (between 10-15 inHg). Once my computer sees the TPS, as the throttle is closed, and that little vaccum....it doesn't know what to do.
So I get a very rough, rich, high idle that is unreliable sitting there and launching.
I do not have a WIP tune to upload at this point, but any advice until I can get that upladed would be greatly appreciated.
Thanks

I am trying to get a hold of a copy of the current tune, and the guy that has the car right now...Not having much luck at lunch time
Plan to give me a call reguardless, I may not be right by the car, but at least we should be able to go over some things on it.
Anyone else have expirience with big cams & idle problems?
