Default HELP

Before any LS1 edit tuning, my LTFT were like 18-20 at cruising. so i added 5% to the maf table. more autotap = adding another 5% to maf table.

I am still running 9.5% on LTFT. i tried to add another 10% to maf table and i get errors in the upper raw maf frequency(hz) range, the values is becoming to large. anything over 11250 hz and it threw up errors when trying to multiply the table

what is the best way to get ltft down since the maf table is maxing out in upper maf frequency end?

i heard not to mess with injector flow rates.
So what is my best option. my car just loves the gas!

There is an upper limit on the MAF table, I believe it is 510 or 511. You can change these to the maximium and then multiply the rest of it by the percentage you want but not the upper ones that are already max'd out. Use Auto Tap to test with Auto Tap to see what frequencies you are reaching, you may not even be getting to the upper ranges of cells.
