It's not 23* in the tune file though. Its 23* at high load, but your engine doesn't pull that kind of air. To be able to accurately reference spark, you need to have an air mass reference as well (and NOT the PID based solely on the MAF).

Yeah all the multipliers have been disabled...

And dc_justin, I see what you mean, but I'm still a little confused, why isn't it pulling that kinda air? It's a 218/228 cammed LQ9 in a SSS... My 5.3 was all the way in the mid .030's area...

Mine hits around .90-.92 grams/cylinder. It should be somewhere around .8-.9. That's where you aim to set your timing in the spark tables.

6.0L at sea level with that cam and 70* temps would be .82-.83g/cyl at peak torque (cylinder air mass and torque are directly correlated). Temps go up, that number goes down and vice versa. Same with elevation.

With this table you can add timing for specific fuel ratios so that you dont have to mess with the base timing tables at heavy loads. I love using this table, it does make it easy.

And I agree with you Justin, I just dont think he is pulling the airflow to be runnning at that range of the timing table. I see that he is running right about what he is commanding for this setup.

I see, thanks guys!
