'ghost Cams'

[Barra]

Have a look. "There are some parameters missing to make the idle quality up-to-par with where we'd be comfortable releasing it. As well, Ford has shown interest in possibly patenting the technology that is used to make this cammed idle tune, so out of respect for that possible patent, we've stopped actively pursuing the idle fixes or interest in releasing the tune.

Any thoughts, comments. Few other vids on there.

So it's a stock car with a tune made to make the car sound cammed? Is that right?

[Ralph Wiggum]

Generally when my car idles like that its due to me making an error in the tune.....

Kinda cool and kinda freaking pointless at the same time!

on my old ef when I tuned that with a j3 chip, I could give it a stable idle that was lumpy or smooth as silk. Once I put a cam in it, I could amplify the lump even more. Or make it smoother. Both ways would hold a steady rpm. But I always tuned that car to have the smoothest idle possible. Even with the 220@50" cam, I did my best to make it smooth. More lumpy is always less efficient.

Funnily enough it doesnt matter to some people how much smooth efficient power they have they still want that rough idle if they can get it.

After listening to those videos again, it sounds like just a lean condition and maybe a little less timing. You can actually hear the lean lump and then car cycles back and then lean lump again. I'd love to see a wideband on it.

Just turn your crankshaft one tooth round on the timing chain.

My ute did it when the tensioner bracket broke & the chain jumped round a bit. Luckily the engine didn't suffer any damage but it sounded pretty lumpy @ idle.

Yer just retard factory cams, take a little timing out. Hey presto!
