I had nothing to do with tuning this car, but I assume it is part of the "anti-lag" feature. it retards ignition timing and over fuels to allow the mixture to burn after the exhaust valve open. This lets the force of combustion be used to spool the turbo, not push the pistons down. Very helpful on cars with large turbos that need boost to stay up between shifts and out of corners.

it's called backfire, when the hot exhaust gases mix with unburnt fuel and ignites

the fire at about 1:30 when he goes into overrun is insane.... that's some looooooooong duty cycles!! haha

fuel dump pretty much, it's running super rich. you see the dark smoke also? good indicator of left over fuel in the exhaust burning.

Adil888 (December 31, 1969 at 5:59 pm)

can anyone explain me why there is a fire from exhaust when he changes the gear
