low timing and lots of Knock Retard! log and tune posted

[MikeVank]

Ok starting to get really confused here.

I am having issues with my timing, Here is the problem set up:

2003 LQ4 bottom end
317 heads ported and polished, decked 0.030" (10:1 CR)
Comp 54-424-11 cam 212/218 @.050", .558"/.563" lift, 115 LSA
HD timing chain
TBSS Intake
92MM TB
Melling 10295 Oil Pump
Siemens Deka 60LB EV1 injectors
NGK TR5GP plugs
Chromoly pushrods
LS2/LS6 MLS Head gaskets
LS6 valve springs
Rocker arm Trunnion upgrade
Running 93 octaine

I have a super conservative timing map and the knock retard is still pulling tons of timing. At a base of 11* and KR is pulling 5* for a total of 5*

I have a list of things that I think that could be possibly be causing the KR:

1. Some thing is really messed up internally (least likely)
2. plugs are too hot (unlikely)
3. frame contact (looked pretty good, has min 0.5''clearance and motor wont move much)
4. sensors are picking up the injectors (maybe?)
5. bad valve stem seals letting oil into combustion chamber (no visible exhaust smoke)
6. Actual spark knock

Thoughts?

Do you have a wideband? Are you running super rich or lean? Do you have the right MAP sensor settings for the MAP sensor you're using? Do you have the proper injector data?

You have nearly four seconds at 3600 RPM, is this on a load bearing dyno?

We have tuned our VE tables with a wideband and our AFR is right where we want it. The MAP sensor is factory and so is the data for it. I believe the injector data is correct, I pulled that data off of here somewhere from a tun that was running the same injectors. I just calculated out the different flow rates for our setup. We are not on a dyno, all on the street as of now.

Hmm, well I only noticed your knock table is quite a bit lower than mine (mine is more or less standard for a 99 LS series, although the engine isn't, see sig). Below are the differences, a minus means yours is less than mine. Also although its not directly relevant, your injector table is 'flat', maybe you have a different fuel pressure system than me?

Our fuel system is using an aeromotive A1000 regulator vacuum referenced.

your list of parts shows deka 60's and your flow rate shows 70.4

That flow rate of 60 lbs at 43.5 psi we are running the injectors at 60 and that raises the flow rate to 70.4 lbs
