A member is testing out jetchip right now. 400$ and they modify your ecu.
Those eBay chips are garbage.

Is there really such a thing in today's age as a performance "CHIP"? I thought now all that can be done is a performance tune.

It is a term that is greatly thrown around and misunderstood. Being "chipped" goes from getting it tuned by a professional to putting a cheap Radio Shack resistor on your car...depends on who you ask. Now, ebay stuff won't get you anywhere. Scams are what they are. Handheld programmers vary, but for most applications modern applications, they don't do much, especially for the cost. Problem is, modern vehicles are so computer controlled, that they pretty much have to be "hacked" to change things. This can be very time consuming and costly, and still not be complete. Different eras and car makers are "easier" to get into and change than others, but it gets done.

It's not like the car's PCM, TCU and ECU are like audio controls. You can't just move the slider over to "drive faster." That is, if you can get into them at all. It's very precise work. I mean, it's not like car makers give away vehicles to test and work on to figure out what to do. I'm being extreme here, but what if someone makes a fatal error in a code and the engine over revs and drops a gear? Messed up engine and/or transmission and no car maker will warranty that.

now, taking this into consideration, tunes are out there and they are for real. I have and had them, with real results, no "it feels faster and peppy" stuff you hear people say. Interest in doing tunes will drive who and if and what will be available. Most Sonatas are rental cars, family carriers, grocery getters and most people are not looking to do 1/4 mile runs with them. While there are people who do want more out of them, the greater amount of people want that drivetrain warranty of 10 years/100k miles to stay intact. If you're jacked up tune causes an issue, that's on you, not hyundai. but some choose to pay to play, and that's part of the culture.

Jetchip is actually the name of the company. They won't make a "chip" for the Sonata. Not a usb you plug in, not little module you put in between two harness. They will figure a way to get the on board to change what it does. They may figure a way to get software to get more out of the Sonata, that they will get onto some type of device that can interact with the computers.

Handheld devices, might be an option they go for, but that will be short of what other vehicles are able to have done. The ones that have clear and far the best luck with handhelds are diesels. They can really get changed into different animals with handhelds, at levels gassers can't reach.

only time will tell what comes out. SOMETHING will, but how effective and how much it is really worth, in the long run, only time will tell.

Problem with aftermarket maps is they are usually a static tune, so they usually can't adjust the fuel based on anything other than revs and throttle position. The difficulty here is that every engine, no matter how similar, requires a slightly different mixture than the next, these static tunes won't get the maximum efficiency. Efficiency =power.

You also suffer in the regard that it cannot adapt to your driving(usually), and will usually fuel excessively for regular driving. Running rich will poo out spark plugs and exhaust sensors, amongst other things. In summary, you are likely to experience very small gains, to be noticed only by placebo. Much better to improve the cars exhaust system(airbox's are designed to improve airflow and work better for smaller engines than a pod filter(in standard cases). Advance your timing with the use of a
cam kit. Increased fueling would then provide a substantial gain.

Perhaps out of context, but would apply that to other parts (i.e. mud guards)?

The simple answer is chips were used in the 80s when car computers were fairly simple. Modern ECU's are complex and every aspect of the car is controlled. You can't replace a chip any more.

I do find that if I'm eating Doritos I get more accelleration than I do while eating Lays.

Very out of context, but yes it does, sometimes. ebay can yeild deals and trash. It's a risk / reward in dealing with stuff like that. I have had good success on ebay, it the past, but I know how much junk gets sold on their. Some ebay "company" makes outlandish claims and sells you garbage, then they disappear with your money. Once the negatives get too high, they start a new profile. At a real, brick and morter store, they have a harder time disappearing.

Truthfully, I don't use ebay much anymore. So many internet places out there, I can generally find it somewhere else, online cheaper. And if it were a little more, sometimes it was worth it knowing I was dealing with a "real company" that would actually have customer service, should I need it.

in addition to what destro has elaborated,

cost of "legit" chips being anywhere from 200 to 700, i would prefer a good tune from a reputable tuner with theta turbo engine experiences for that price

I have fitted one of these to my i30 CRDI and it is builds revs a lot quicker from stock nothing really happened until 1900rpm and was all over by about 2700rpm now it starts at 1700rpm and pulls hard to about 3000rpm. This is the site if you want to have a look
