OFT tuning for stage 2
I will be fully catless stage 2 OFH + E85 here within a week or two, and I have a question on the mapping.
Shiv has the canned maps available for stage 2 UEL E85 if I recall correctly. I'm somewhat comfortable tuning as I've self tuned my WRX for years, but NA is intimidating me a bit. What needs changing (if anything) to try and extract more power out of a fully catless 2.5" free flowing exhaust, K&N panel filter, and E85?
With the old WRX stuff I could easily get more power than the off the shelf tunes, but here I'm not sure. Could it use more ignition advance, or should I try leaning it out a bit? E85 is pretty forgiving stuff. There were so many people on the WRX platform that information was plentiful.
Do I need to modify the valve timing tables?
Thanks for any pointers. I'm continuing to read as much as possible, but am just curious on what you guys have found that helps.
