Total timing vs initial timing for max HP.

For those of you who have not seen a EEC timing table, I attached one to this thread. I believe 302man's method of setting up a blown engine with the BTM is a good idea for "spirited" driving. You'll see the table and it's modifiers for driving at less than wide open throttle (WOT) and then at the bottom is the table used for WOT. Keep in mind that this table reflects timing added ABOVE base timing as the computer can only add to the base setting. This is ONE A9L table and if you have one, this may not be your exact table as they do vary from car-to-car and year-to-year.

Notice that timing can actually get well beyond 30* and that is why 302man's suggestion works as well as it does. At WOT the EEC is trying to add timing at the same time the BTM is trying to pull timing. Even in a naturally aspirated car, it's good to pull some timing as rpm increases to maximum and then add it back as rpm falls to keep torque as close to peak as possible.
