What is the best way for me to lower timing?

2006 C6 A6 paddle shift

Curently running 75 shot with 100 octane if I run a little less octane (98) I see KR from 5-6k only in 3rd.

How much timing should I pull if I bump from 75 to 100 and 150?

I think you pull about 2 degrees per 50hp shot starting at a 100 shot.

 

What style hit, wet or dry?

Wet NO Plate

 

anyone

 

how much kr? could be false also especially on 98 octane. with my current tune, i get kr sometimes but not always on the same type of runs. i tried pulling timing but it didn't help and actually gave me more kr sometimes.


generally on an ls1, i don't think timing needs to be pulled for a 75. don't know about ls2's but it may very similar. kr happens and pulling timing may not be the solution.

what's your afr look like?

could just try taking whatever amount of kr is showing up out, if it helps, try working it back up. on a 75 shot, i would run regualr gas that you use for NA and work the tune for it. i don't think you need the 98-100 to run a 75. and how many runs have you logged with the kr?

 

I have run it with less octane then I get KR the less 100 the more KR, dump the 100 in and KR goes away.

I am running higher timing than stock thus the need for the 100.

I have logged 22 passes on the spray and 50+ NA.

My Inovative shows 10.0-10.5 on the spray but not sure I trust it yet
It reads 14.7 at idle and 11.0 on motor I know its rich but it runs great and is faster and makes more RWHP than my friends same car so it cant be too bad???

O2 volts are 910-950 in 3rd sample above but the line looks more like 930's
