Parish, XLR8, Big Tex--edit timing question?
What tables do you guys change in edit to get more timing?
I'm getting between 11-15 degrees depending on how hot my IAT's are. I want to go with 17 degrees across the board and see if it gains me anything.
I'm confused? Looking at the high octane spark table, I should be around 11-12 degrees of timing. Thats not factoring in any parameter that subtracts like IATvs MAP??
There must be something else that contributes to timing.
Help me out guys, whats the easiest way to do this?

There is a lot that goes into this. For our trucks, none of us has exactly figured out why timing values don't come out like the programming says. The main items are the octane tables. But, there are a few support tables that either add timing or remove timimg when you trigger certain functions. IAT for instance; if temps are high, it will lower timing. Also, it seems like each newer version of LS! edit has uncovered a new table or two that unlock some of the mystery.
OK - You really need to log your MAF and rpms to modify the octane tables to know which cells you are using. But in general, I usually start at say 3000 rpm up to 6000 from 50 down to the bottom of the chart. Make all of these cells the same value. Put them at 15 or 17. Then do some logging and see what effect it had on your timing. Do the low and high tables. Watch for knock.
See what that does and report back.
