In process of adjusting the VE tables to get my STFT+LTFT values closer to the more ideal +10 to -10 range on my 6.1L supercharged hemi.
I write the new tune, cycle the ignition key off/on twice to be safe and then disconnect the battery for a couple minutes to erase the old LTFT values.
I then start and drive the car which drives fine.
My question is: How long or far must I drive and/or how many heat up/cool down cycles are necessary before I get valid STFT+LTFT tables to check my progress??? (I graph each bank RPM vs P-Ratio.)
Guess I had a second question: What's with the odd RPM values on the VE tables??? (416, 607, 800, 1088, 1600, 1984, 2489, 2991, 3495, etc.)
Thanks
