Not that I think it's healthy long term, but has anyone intentionally set the far left 10% load cells to super rich settings on purpose?
Basically you are in open loop at 5500 and above so it uses the AFR in the tables. Curently with the factory 11.8 AFR set in there I usually belch flames if I lift off at above 7k rpms in 3rd to 5th gear.

Heh, I haven't tested the super rich settings at 5500+ yet but whenever you completely let off the throttle above that range it should momentarily drop to around 10-20% load range before it goes full lean and light up that excess fuel. If there are cops nearby it's pretty easy to avoid running the higher RPM's, at least you shouldn't be speeding by them! I know that right now if I hear the pop after letting off at 7k+ then I was likely shooting flames. They can be seen during the day if you look for them (according to people I passed at the Watkins Glen Road course) but the real show is at night.

I can get it to shoot flames everytime I downshift. All I do is hit boost a little then downshift to second. http://www.youtube.com/watch?v=MGEmU7Exkbg
