01 timing advance.... Guys,I put my friends 01 SS on the Tech II yesterday to see if the 01 and 02s really have less.. He has a SLP lid and Dual Dual and thats it. With 0 knock his car had 18-19 degrees from 2700rpm to 5000rpm. Past 5000 it slowly moved up to 27 degrees by 5900rpm. In contrast my 99 has 30 degrees my 3000rpms and never goes lower
than 25 degrees from 2500rpm and up. The car feels real strong and only has 3000 miles on it. 02's were between 900-920 range with coolant temps at 195 degrees...Joe..

Re: 01 timing advance.... normally i see the same amount of timing as your friend does. No more than 28 degrees. With my MAFT I can now eek out 30 degrees of timing at 6000rpm and 32 degrees at 6400...wierd

Re: 01 timing advance.... My '01 M6 WS6 is seeing only 24.5-25.0 degrees advance by 5,700+ RPM's in hot or cold weather. I have just a direct-flo lid. My '99 A4 would hit 28.5-29.0 degrees advance with the same lid. 0 knock retard in both cases/cars.

Re: 01 timing advance.... Just out of curiosity, does that extra timing actually give us any hp? From what I understand, the timing is low because the cam doesnt need that much timing. Has anyone proven that 30 or more degrees of timing actually provides more horsepower? Id like to know what the real world gains are before i go screwing around with my car.

Re: 01 timing advance.... Guys,
My 01 SS timing is the exact same. i get around 18 deg. for most of the RPM range and actually never get more than 24-25 or so at only the highest RPM. I had read from other posts on other boards that the 01's and up have more timing advance built into the camshaft and thus don't require the same timing as pre-01's.
On a side note, with only a Lid and Filter, my 01 pings at high RPM on 93 octane. I have reduced it with my MAFT cranked to +14 on the WOT side but still get a bit. I'm hoping that a freer flowing exhaust will reduce some load and eliminate the ping. I'm also going to change the plugs and see if that helps...... any thoughts ??
Regards,
Mitch R.

25.5 seems a bit low. The only odd mod I have is a pulse dampener/fuel pressure regulator, which ups my fuel pressure to 63psi.
Other than that I'm not doing anything special. My MAFT is set at +1 -3 to get those high timing numbers.

Re: 01 timing advance.... I pulled my MAFT and MAF ends off yesterday and put my stock(slightly polished, not ported), de-screened MAF back on - and the car runs the same so far.
ATAP'd and L-trims were the same, but O2's were better at .88-.89 with no KR, and timing was the same 25.5 at WOT - and no KR.
Since I only picked up 2 rwhp and no rwtq with the MAFT and ends, I'm leaving them off for now. In this weather it became too much of a pain to keep tuned! My car would always end up rich and KR would show up, even when it was rich?!?
I make this post on this thread because my whole point of the Maf ends and MAFT was to get more timing and hopefully more HP, but it didn't happen for me on my car...

Re: 01 timing advance.... I say in stock form less timing is not bad since 2001+ seem to make more power everywhere, but with a cam and definitely with heads i think more timing would be beneficial. Even with exhaust work (less back pressure) i think more timing would help. Has any one found this to be true?
