Are the S1's better for the stock 8 turbo, or S2's?

 

Can you post vid of your car idling? I hear mix review of how this thing idle.

Thanks

 

Oh well, I'm the new user of the s1 cam in an ix.
At first, the idle is just a little bit rough compared to the standard cam before tuning.
And after tuning, the idle is still same, a little bit rougher, but you won't notice the loppy sound, you need to place your ears next to the exhaust, only you can hear the different idle between s1 vs stock.

Then, i search through other thread, and yeah i found something that can create the lopppy sound. So i did a test just now. And yes, the sound of the lope can be create or change for minimize/maximize.

When AC Off
Minimize, the sound can be hear clearly, is like 2-3 sec per lope.
Maximize, ohh hell is like scubby!

When AC On
Minimize, the sound can be hear, but is like 5 secs for a lope.
Maximize, the sound can be hear, is like 2-3 sec per lope.

But when AC On, before the compressor kick-in thus increasing your idle, the sound is same as when Ac Off.
I like the maximize option, but my car just don idle nicely, or maybe i'm having too much point on that.

Btw, i think i've handled the stalling issue. But without adjusting the BISS. Just play with the idling mapping.

 

I installed S1's in a IX with no tune car drove and ran fine
