Hate to say it, but he is the only vendor I have ever heard of that says this.seriesIIIChump said:But Zoomer recommends a cam with overlap be tuned to +16.4 at idle.
When I installed my cam, I get -16.4 to +16.4 (at idle). It jumps around everywhere. I've played with my afc so much and it doesn't do jack. From what I gather, the only time LTFT's become in effect is at cruising and WOT. Now when I cruise and go WOT, I see around +.7-.0. I know I don't have a leak anywhere.John F said:Hate to say it, but he is the only vendor I have ever heard of that says this.
I've tuned 3 different cams in my car and quite a few other friends as well now and have always had my LTFT's as close to zero as possible through the entire RPM range.
Go look at LS1tech.com and see if anyone else thinks the same thing.
V6 or V8 doesn't matter, a tuned engine is a tuned engine.
That's one explanation, but it sure isn't the correct onejk99gtp said:Here is link explaining about LTFT's and aftermarket cams:
Hope this helps a bit.
But if the car is super rich or super lean won't it effect the idle? I mean if the car is choking on fuel it would idle poorly and vise versa for lean. Right?Just the same though, this is only intended to reduce the rich exhaust smell on cammed cars, and has nothing to do with power.
