    I'm puzzled why nobody has been able to replicate this sound that people seem to love? (Mainly the backfiring on deceleration form what I understand). Since we are talking about such a limited, non-critical condition (no throttle which would correlate with high vacuum) and, I believe, backfiring is usually caused by excess gasoline, it seems someone should be able to trick the engine in to replicating what the original software did.
    Is there some reason that more sophisticated ECU modifications can't be done with Ferraris?

    Ferrari made the changeto comply with the EPA import cert before they ended up with a issue like VW has.

    ECU is encrypted and can't be modded

    The only way to replicate it is to get real proficient at not completely releasing the throttle but leaving a credit card thick input on decel.

    It's 2011 and 10. I have my original software. Sounds awesome. Lots of pops and overrun. Love it.

    It sounds awesome especially in second and third gear. One of the best features on the 458.

    Popping is caused by a lean condition.

    My hunch is that Ferrari quit firing the injectors and cut spark to take power out of the engine for the 3-5 revs when the transmission is working. No throttle can be that fast.

    Ferrari did it to conform to the EPA cert that allows them to import the cars. The fuel burning in the exhaust during overrun caused them to exceed the tested/publish emission #s. That is why it is a required update on all 458s.

    That's why I told my dealer not to touch my software. Just change fluids. Love the sound with my Ferrari sport exhaust cat back.

    So if it is extra fuel burning in the exhaust, shouldn't it be possible to sense high vacuum conditions (deceleration) which would then do something to cause the ECU to enrich the air/fuel ratio. Perhaps changing the input from the temperature sensor could work since I believe a cold engine runs richer.
    This may not be the best way to do it but it seems that it should somehow be possible to change input signals tricking the ECU into sending more fuel to the engine.

    Is there a video like that for the 488?

    You are kidding right? Please put a smiley face at the end of your posts so we know your not technically challenged.

    I am definitely technically challenges which should be obvious with or without a smiley face. I'm just surprised that technological geniuses cannot figure out a way to change a fuel mixture under the one limited condition of deceleration. :) :)

    I love it. I think I posted this before but once I was hitting an on ramp and half way around came up on a pretty nice Mustang and had to back off. The 2010 458 started sounding like the most aggressive thing you can imagine and I see the Mustang driver's eyes in the mirror glance up in disbelief. It was just a moment of connection between two car people. At the end of the on ramp he waved me around.

    Is this a US only thing?

    I wish I knew the answer. I do have some related facts.

    I have a several cars in my collection. All of my cars are stock as they came from the factory.

    All of my recent American cars have a loud exhaust sound. Some can be muted.these include A c7 Corvette, Z/28 Camaro and a Shelby Mustang. This makes me doubt it is an American issue.

    My Lamborghini Adventador has a very large, harmonies sound. So That makes me feel it is not an American regulation for foreign cars or even an European requirement.

    It makes me suspect it is Ferrari related issue. I plan on keeping my 2010, 458 Ferrari as it came in 2010. I love the sound.

    I One last data point. I drove a twin turbo Porsche. This is the one with variable vanes so no hysteresis in power delivery for you technical types. It had no sound, none. It was a great performing car.


    Hopefully another poster will be able to answer your question better.

    Best

    Cool, thanks for the info. I ask because I haven't heard about the issue before (I'm in the UK) though I've only recently seriously starting considering a 458.
