I have 44* right now. Just want to make sure it's not too much. Don't hear any misses but I don't have knock sensors either.
It's only 3-4* over stock so . . . What do you guys think?
Is 45* too high for low load low rpm cruising?

I use up to 44 degrees of spark advance at .20 g/cyl and less. That pretty much equates to a downhill-level pavement cruise. I usually hit those values in 6th gear..seems to like it and I never get KR/pinging in that zone...
Thanks for the info!
Shawn could you post your High Octane table plz
EFILive Tuner
I run about 4-5 different set-ups depending on fuel type, weather etc.
This one works good for me...within ~15 HP of max..No KR. I would not necessarily recommend it to everyone, but here it is..
Thanks a lot Shawn
How much spark you are using at idle ?

Currently running 26 degrees of Spark at Idle (BSIG).
Hi Shawn, I see that you are commanding 22* WOT ... did you see no significant gains with higher timing?
I know everybody's set-up is different and ours are not the exception but I just want to see if I might be a tad high with my 29*.
Thanks for all the help!

My Heads don't like more than 25 degrees of WOT. The Intake Runners on the Terminator Heads are only 200cc..its a 62cc Head. I think using a 110+2 Cam builds up the cylinder pressure to such a degree that you don't need the additional spark advance to get your power.
So, its within 10-15 HP of Max with 22 degrees. In winter, or on the track I may use 25 degrees, but on my street tune I go conservative with no KR.
I am surprised you can get away with 29 degrees of spark. Do you ping or get any KR, or just have access to good gas?
I run OTC 93 octane.
I don't actually "see" a problem BUT I don't have knock sensors either :(
The shop that installed my 402 and swapped my Ls6 heads/FAST90/Vindicator for my LS3 top-end didn't re-install my knock sensors. The previous set-up could handle 29* all day and I just thought to keep it with the new heads/cam/intake.
I'm going to back off some high-end timing and see if I notice any power loss. It was one thing I was most unsure about; whether or not the LS3's could take timing.
I'd like to do more research and get more input from others with 402/LS3 top ends and see what their max hp/timing is. Have you run across others with similar set-ups that see better results with low 20's?
