how come some turbo car , when they off throttle , their exhaust got fire came out de ?? izzit miss fire-ing sistem or wat ??
Can I correct you there?Originally posted by whatdamn@Jan 5 2005, 00:14
those 250 gadgets are push button ones.
misfiring system could also lead to that or even normal NA cars if running lean(more petrol than oxygen one) then wehn lift of throttle will lead to combustion in the exhaust piping itself.
someone correct me?
dun forget the JGTC cars :lol:Originally posted by jwrx@Jan 20 2005, 01:08
there is a diference between an anti-lag system(misfiring system) and a turbo car running rich resulting in flames from the exhaust.
anti-lag system(misfiring system) is an engine management technique that allows to minimize the turbo lag time. When the driver lifts his foot from the gas pedal the ignition timing is altered with delay (retard) and the intake air and fuel supply mixture is made richer...basically when the driver lifts off..the ECU is still feeding fuel into the cylinders..this is used in WRC to keep the turbo on boost..
What u see in Kl where flames come out of turbo cars is normaly just BADLY tuned cars running a rich mixture, it doesnt add power or help with turbo lag, in fact its damn bad fo rthe car cos the exhaust system is not meant to take these sort of high temps and stress
thank u sifu... wanted to know the answer so long alr.Originally posted by jwrx@Jan 20 2005, 01:08
