I've heard it mentioned a few times, but I can't seem to figure out what exactly it is. So, what does it do? How does it work? And where can it be purchased?

 

its a box tune meaning its a standard like plug in into your computer changes a couple of things honestly you are better off with a tune but im not sure about you 2.4 guys ithink something is out but not sure someone will chime in. im tipsy so u know

 

get a tune.... the jet chip is a scam.... most "chips" are just resistors and will most likely hurt you more than help you...

for you though.. get a tune via HPT (hp tuners)- search for more info... you 2.4 guys have tuning avalivable via HPT

 

thanks I thought they had tuning

 

I like my jet chip. I'm really glad I have it, it's really helped my auto.

 

There are some good mail-in tunes out there.....as long as you give them the proper info on your car. Vector Motorsports is one of them. You tell them the mods you've done to your car and they modify their tune based on their experience with the 2.4L engine (they most likely use a program like HP Tuners). I bought their tune and I'm very happy with it. Based on performance numbers with my Dashhawk, I gained 10-15 whp with their tune.

 

Jet Chip (the company) makes a module that plugs into your ECM. it is a piggyback system that gets plugged into the system and changes the information sent out to increase timing and fuel based on tables they have set up -- like a tune.

Pro:
Cheap as a tune
FAR cheaper then HPTuner set up (and then you get to learn)
you can remove it whenever you need to and reinstall it
you can sell it
It works for me
don't have to rely on somebody that just bought HPTuners and hope he knows what he's doing

Con:
MAYBE not make as much HP as a tune (IF you can find someone that truly knows what he's doing)

 

eff Jet chip, HP Tuners is the only way your gonna be able to get a full tune.

 

The Jet Chip MODULE is not just a resistor. Jet Chip has been making computer enhancing electronics that work for more than 20 years.

As you can tell by the posts to your question there are posters who like to shove their opinion down your throat. They have no intention of trying new products, can only bad mouth what they're ignorant of, and can't express themselves without foul language.

You can get the Jet Chip Performance MODULE through JEGS and Summit -- both of these companys are top notch, have been around a long time and sell things that work -- they don't push garbage.......

 

Ya you don't have to go far to find somebody craping on jet and I wonder how many have even used it with their cobalts. I have no opinion about tunes as I never tried one as I could find anybody locally with experiance. But at least I'm not giving and opinion about a tune I never tried.
jet works perfect for me so far.

 

Unfortunately for me I have seen, and read, about people that screwed up cars when they thought they were "tuning" capable. I won't "jack" threads of posters that talk about tuning and/or tuning problems and tell them they should have gotten a Jet Chip Module.

You want to see the problems tuners have with their tuning -- go to the HPTuners website and read the problems yourself.

Read a few threads here on CSS.net and you start to realize people don't understand tuning -- like: Why do I have to use higher octane fuel with a tune? Because the reason for tuning is to increase performance -- performance tuning involves advancing the timing and higher octane is needed to keep from "pinging" -- pre-ignition. Anybody that doesn't know the answer to that simple question shouldn't even consider buying HPTuners.

 

a friend has a jet chip. while he was being tuned with hpt he was reading 13.8:1 a wot at 6000rpm with that chip. that is insane lean. actually losing power in that range

 

He bought a Jet Chip Module AND went to get a tune? He likes to spend money doesn't he

 

lol, he had it, and I told him to ditch it. lol. go get a proper tune. its worth it

 

If he doesn't need it tell him to open it up and post pictures...........

 

when i see dyno numbers, like in the actual jet-chip thread, i will consider buying it. but its too expensive just to "try" and "gamble" on. Im NOT bashing the chip or anyone who bought it. when i see concrete evidence, then i will make my final judgment accordingly. but its too expensive for me to just try out with no real evidence in gains.

 

Absolutly nothing wrong with that argument -- and I have the same argument about "tunes". Just because I can have a "tune" mailed to me proves nothing to me to. I can fudge information with the best of them -- found this out when I dynoed a 2.2 auto -- I trust dyno reports as much as I trust a noob to tune my car!

I can give you the same info people with tunes can -- Just what I feel in the butt dyno:

Before Module: WOT from standstill very little wheel spin (I actually thought it was the performance Pirellis), disappointing acceleration until 4K RPM, then it felt like a switch flipped and the engine screamed to redline. Top end -- I don't know and will probably never know.

After Module: WOT from standstill lots of wheel spin and engine screams all the way to redline. Top end -- Ditto.

 

Thanks. You definitely gave the best reply.

 

can it void warranty and can it screw anything up in the car?

 

before i had my cobalt i had a 92 ford ranger. I was always on the ranger power sports website. There was a guy on there, i cant remember exactly how much, but he did a dyno with and with out a jet chip, and he actually lost hp with the chip. i was thinking it was like 8hp compared to stock... no lie

 

Hmmm good question the JET chip won't as long as you REMOVE it before you take your car to the dealer. Now with HPTuner it will because the tune is permanent unless you can find someone with the stock settings saved.

 

so it's less headaches to get a jet chip so to speak but can it screw anything up on the car? like for instance someone at the dodge forums said his ac would not work with it on but worked when he took it off

 

If it does something like that the module is most likely defective. So far from what I've seen only one member on this forum has had a problem like that. Here is the thread https://www.cobaltss.net/forums/2-4l-le5-performance-tech-46/installed-jet-stage-2-morning-thoughts-118040/
the problem he ran into is on page 2

 

The position on the ECM that the module attaches to only has so many connections (center position). the specific connections are for the injectors, timing, HO2Ss, MAF, MAP -- engine functions. There is no way the module can affect the other equipment. For example, the bottom connector controls the cooling fans -- if you insert the module in the bottom connector it will certainly affect equipment it wasn't intended to affect....

 

yeah thats right. I forgot about that.
