Truck is a 4.8 turbo, fueling is close to dialed in. No knock at all, running 24psi. How does the table look? I know i can add a couple degrees at wot but wondering if there should be more in cruising areas or just more in general. Trying to pick up a little acceleration when coming into boost.
Looks fine to me w/o knowing the compression. Put it on the dyno
u will most likely not see knock on ethanol until ur way past peak torque/hp, best to adjust timing on a dyno so u can see actual gains/losses
LS generally won't make power over 28 degrees WOT. Cruise up to 55 degrees with a cam. The Bi-directional control in the scanner is great for finding optimal timing in different load and rpm areas when on the dyno.
Looks a little backwards from what I typically see them like. I typically pull a little timing around peak torque and then feed it back in as rpm increases. You have peak timing around peak torque and then pull it as rpm increases. While you may not be seeing knock, it's likely not making anymore power like that.
Peak tq usually highest cylinder pressure so requires usually little more fuel and less timing
/\ /\ /\ yes. And with increasing RPM have increasing timing past peak torque.Quote:
