E38 Knock Retard?

[Jayrcr3]

Is this a Thunder Racing cam?

Vengeance Racing.

Thanks for the tips guys. I'm still learning the tuning software and I'm nervous about just making changes without asking. I haven't messed with the VVE table, but my WB says I'm right on about 12.8 AFR. Vengeance did 3 mail order tunes for me after I installed all the parts and sent them log data, so I'm sure they tweaked it. If I lived closer I would have had them dyno tune it. Where I live we can get 93 octane fuel, so I figure the timing can be bumped up a bit.

I've seen some dynos give lower readings when run is done at lower speeds,
looks like that pull was done in a really low gear..

[Jayrcr3]

It was done in 4th gear.

I run in a standard LS3 up to 24deg at 6500rpm. Timing should gradually increase once past peak torq (max VVE) from say around 18 to 19deg at 4400rpm up to 24 deg at 6500rpm on our 98 octane fuel in NZ(rated differently to fuel in the US so don't compare)
Any cammed LS3 will run more timing than this and the peak torq point may be much higher say 5600rpm so the timing "low point" will need to be moved accordingly. To start with find your peak torq point (highest VVE) say 5500rpm > throw 20deg in here, blend up to about 23 to 24 deg at 6500rpm.
At 2000rpm fully loaded start at about 20 to 22 deg blend up to 24 to 26 deg at around 4000rpm, blend down to 20 ish at peak torq then up to 24deg at the limiter. Should show as a nice gradual curve not steps. This is a guide to get started then you have to dial it in on the dyno mate.

Thanks for the advice. I will give it a try, and see how it comes out. According to my dyno sheet max torque is around 4800.
