I don't see how this happened...I'll take your word for it. So now you have a super sports mode until everyone else gets theirs fixed. Just how did the sports mode improve. It might be obvious, but it would help a little if you gave an in depth review.

My fiancé drives with the sports mode most of the time...unless she forgets it's in normal mode, then she quickly changes it back to be more sporty.

Did they buy any chance put your car on the lift and misplaced one of the arms put a crack in your exhaust system? Won't be the first time, this is more of a major disaster by doing this.



Several guys on that Cruze and other sites complained about this, look at your exhaust.

One of my learning kids likes to drive sport mode; likes the steering, engine braking and the quick burst when he finally gets up his nerve to pull out. A lot of the route he drives most often (work) has a mile or so of near level, no stop 45 mph driving and in SPORT mode it runs at 2500 rpm and doesn't upshift. ECO runs under 1500 in the same stretch, both directions (he drives there, I drive home, 5 or 6 hours later I drive there and he drives home).

After reading your post with your fiance driving in sports mode most of the time, i figure the reason why i catch the exhaust system sound louder is because i got the Elantra just b4 xmas and i been using Eco mode the whole time! Then i decided to test the sports mode after the update! Haha maybe i just need to get use to the nice deep tone everytime i pass a (slower) car!!

I have found exactly the opposite. On the highway, all 3 modes get into high gear and drop the rpms fairly low for rougly the same mileage. It's around town, cruising at 45 and/or accelerating up to it where SPORT will run the revs up much higher before shifting. As I mentioned earlier, on the same stretch of road that is very near level (same results in both directions) for a mile or so at 45 mph, ECO stays at just under 1500 and SPORT at 2500. Drives me nuts when my SPORT preferring kid is driving because I feel like it needs to shift (I drive ECO nearly all the time).

Feel the worst TV shows were the A-Team and the Dukes of Hazard, wanted to cut violence, but they really did some very stupid things and never got hurt. Oldest son was brainwashed buy these stupid shows that had a pronounce affect on this driving, was jumping on him all the time.

This was completely unintentional, needed a part from our local wrecking yard when we could go in, can't do this anymore. Asked him to come along, found a car exactly like ours that he saw. The front end was all smashed in, apparently both the driver and the passenger were thrown through the windshield because there was bits of flesh and blood all over the place. When he saw that, he was shocked, but this sure slowed him down, and became a safe driver ever since.

It has been reported making our cars so quiet today, giving a false sense of security. Really do not advertise even wearing your safety belts, your air bags are worthless above 40 mph, he is driving at 45! Recently a neighbors two teenage daughters were killed, our local newspaper just printed a short article on page five. The parents were devastated, just sold their home and moved.

With all this so-called safety stuff, highway deaths remained about the same, but the injuries have more than doubled, now we have to put up with texting. Daughter-in-law was recently rear ended by a texter and my grandson was in the car. But fortunately neither was injured. Sure have a bunch of nuts on the road.

Eco, Normal, Sports mode, ECM update doesn't have a darn thing to contribute to a louder exhaust, sure you didn't get a crack someplace in your exhaust system?

Talk about insane law enforcement, kid was stopped because her little four banger of a car was making a put put sound, just given a ticket, no fine, but had to provide proof it was repaired, Not even close to a jet landing at our airport, a semi, five locomotives pulling a 1.8 mile train through town, definitely not like a motorcycle with straight pipes.

Cause was all this dam road salt put on the roads, rusted out her muffler, had to put a new one on, she just showed the receipt for the new muffler.

Its okay with me if they use flashram for trouble codes, learning modes, and radio stations, GPS, even menu setups. But everything else should be stored in PROM, and they should write the code correct the first time!

They did have to do this with OBD I! Sure keep a close eye on your battery and its connections, the only filter for the alternator, in can generate spikes up to 150 V that will wipe out your code with flashram, only take 0.5volts on the wrong pin to do this. At times I wish I didn't know this stuff, a million transistors to fire an injector or a spark plug, but been carrying towing insurance ever since. We could use a linear voltage regulator to prevent this, but the bean counters and stock holders carry a lot more weight, so switching the field coil constantly to save a buck, each time that field collapses, we are talking about what Tesla discovered over a hundred years ago, and doing this from anywhere to 50 to 400 times per second.

To the best of my knowledge EPA emission requirement are only to a given year, no need to change this, but also requires a hardware change, can't do this with firmware. You still can drive a 57 Chevy without a catalytic converter, seat belts, or air bags.

Some "green" guy in a house painted white someplace learned about this, so came out with cash for clunkers to get this old stuff off the road. It's key benefit was to skyrocket the cost of used vehicles so poorer folks could not afford them anymore.
