More questions. My VE error is within +/-1% now thanks for that. So now I'm adjusting my spark tables high and low. It was pulling timing out in the higher airmass and rpms so I dropped the lower half of the table down 1* without seeing much of a change so I repeated and it seems like it just continues to pull even more timing in my log. I got down to 5* less than I started with and still seeing it pull timing and more drivability issues. I reverted back to the table how you had it and it got better. Still seeing retard but not as much and drivability is better. Do I need to try advancing some?
This log is with the spark table you had setup and it just got worse as I adjusted it.
It's acceptable to desensitize the knock sensors a reasonable amount. Changes here are based on a 99 vette file. Newer C5's have even less sensitivity.
Would you be able to feel that small amount of timing being pulled out? It almost feels like a misfire. Or is it more likely I have a misfire that's causing it to pull the timing back?
