Default Soften boost control targets, pull timing, add fuel for track?

Do you guys adjust your boost control so that the boost hits more gradual when at the track? Right now I have mine tuned to hit max boost as quickly as possible. I'm concerned about breaking the tires loose at the wrong moment.

Side question. Do you pull spark and add fuel across the board as a safety margin on a DD tuned car? If so, how much.

Learn to control the loud pedal rather than the stereotypical binary SM throttle control.

Edit: Part two.

I run the same spark table, even on 91-octane because I'm such a bauce. I have a ton of head-room though. You can use det-cans and record them through an mp3 player and listen for det when the car is hot or when it's hot outside for a definitive answer on detonation.

I don't worry about boost control, and whatever I have is easily controllable. Show us a 2nd or 3rd gear pull and post your spark map?

+1 to throttle control.

I don't retune anything when I go to the track. If you think your tune is that ragged edge, you should probably pull a couple of degrees anyway.

yep, like what huslter said. I think things maybe easier if you spool at an rpm that you don't visit too often.

for example, at RA the only time I am ever below 4.5k rpms is on turn 7 to the backstraight where I usually keep it in 3rd and maybe drop to 3.8k or 4k rpm at the lowest.

If you are spooling in that area, this may get uncomfortable, especially since you actually track out before the apex and getting on the throttle is usually very early in this turn. But I would imagine once you learn that you are in that zone, you will be careful with your right foot, or just get faster so you can stay spooled.

This is why I like TPS controlled boost targets.

Track stay out of this until you have a turbo miata.
