Some opinions would be nice maybe people who have em if they can say the pros and cons they cost about the same, and their both very easy to install.. so anybody care to persuade just being friendly

 

jet chip is trash..

what year is your car?


search button please

 

Stick with trifecta no matter what. We have had no problems with it so far. Multiple people have had problems with Jet Chips

 

^ +1, i've only read good reveiws of trifecta tunes

 

I have the Jet Chip Stage 1 Module on my 2.4 and it wakes up the bottom end of my engine's performance. I've had it for about 5 months and have not had any problems. I also get PM'd by people that have it and they also say it helps their low end (they don't want to post and get trashed by the "Know-it-Nots").

If you can get a tune that would probably be the best, if not -- the Jet Chip module is a nice addition.

 

you can be hptune why in the hell would you want a jet chip...

 

iam still a kid and naive i look for any option to add hp lol but um i heard h tuners is a quite bit complicated and is their any way i can do both ) thanks for resonding guys

 

what is a jetchip? I live in the caribbean and I bought a stage 2 kit, but there are no gm dealers here so I have no way of getting the tune for the stage 2... would a jetchip work for a stage 2 tune?? I also don't have access to hptuners...and even if I buy hptuners I have no clue on how to use it.

 

They has to be a good tuner in Miami.

 

I'm not in miami anymore.. used to go to college but moved back to the caribbean...

 

Like I'd trust just anybody to tune my Cobalt....

The Jet Chip Module might be what people refer to as a "Canned" tune" but it works, isn't outrageously expensive, and I can take it out (try that with a "tune").

People with HPTuners aren't around every corner -- and I looked into buying HPTuners -- it is not cheap for what I want.

 

Has anyone logged with a Jet Chip? i would love to see some AFRs on that beast. The only upside I see is that you can remove Jet Chips.

 

Yeah I Wana See The True Diff So I Know Im Gettin The Best Bang 4 My Buck

 

Red, did you ever get a dyno done? I thought i remember reading back in the spring when you were buying the Jet module, but never kept up with this place after that period.

 

No I haven't dynoed -- and I don't plan on it because of my automatic tranny. I dynoed a 2.2 auto couple of years ago to try and prove the 2.4 manifold worked on the 2.2 and found that I couldn't get a clean "enough" graph to prove any small increases (or decreases) because of the upshifts and downshifts -- can't control the auto tranny.

 

Sure you can, disconnect the electrical connector, it will default to 3rd gear, which is the gear you want anyway.

 

That's the first I've heard of this. You are talking about the main connector on the side of the tranny right? hard to believe it is that easy!

 

Yup, the big connector where the harness goes into the trans. If you disconnect that youll only have P, R, N and 3rd. it wont shift, because it cant without power.

Theres actually only one wire you need to disconnect(CKT1039/PINK) but disconnecting the whole connector is much easier.
You can also try pulling the "ECM/TRANS" fuse under the hood, this will work too, but may put you into limp mode because it will cause turn off the TCM as opposed to just taking power from the shift solenoids.



Sorry for the TMI. All you need to do is disconnect the large round/oval connector from the trans. you squeeze the sides to release it. there should be a white arrow on top(not always)

 

I have.
I wouldnt put one of those in a car if you gave me $500 and the chip for free.

 

It's not a "CHIP"...Please provide factual backup data when providing your opinions...thanks. These things work for those that can't get a tune.

 

Dont get butthurt.
he asked if anyone had logged it.
I have. and thats my opinion.
I long ago stopped giving a **** about "proving" things like this to this forum
so believe me, or dont. I couldnt give a ****.

but hell. wtf would I know anyway. mid 13s AFR could be just fine.

 

Someone asked if anyone had logged data from a Jet Chip module, because he would "love to see some AFR's" Youre the one getting your butt hurt and resortin to the "I dont need to prove anything to anyone" stance. Why bother letting us know that youve logged info on the Jet module if youre unwilling/unable to share it?

 

You and I had this discussion on another thread -- unless you put a sniffer in the exhaust you don't know what the readings are. My scanner gets screwed up data when I record 19 seconds of ECM data with the Jet Chip module installed. Have no clue why.

And there is the possibility that the one reading you "saw" was defective. The 2.2 modules have been a hit-or-miss in the threads.

 

new aem wideband, installed pre-cat gave me enough to know that it was not a tune id want to run.


you dont need to use the HPT scanner to see that a tune is running terrible.

 

Most of the Jet "chips" simply modify/alter stock sensor readings going to the computer in order to get the computer to react differently and alter the fueling and/or timing. For example on a lot of the speed-density cars that rely on a MAP sensor to calculate airflow the Jet chip will function similarly to a fixed MAP clamp or alter other sensors like changing the intake temps. About the only thing nice is they are a plug-and-play device even though many times you could simulate the same functionality they provide by wiring in a couple dollars discrete component (resistor/potentiometer, Zener diode, etc.).

That's not to say it's dangerous or won't work or won't provide some types of gains, but they are expensive for what you get and there is a potential the car could be running too lean, for example, if you use the chip with other modifications (but that goes for any tuning device that wasn't custom set up for your car). Without some extensive testing it's hard to say what exactly the Cobalt/Ecotec version is doing and I'd want to see some verified independent gains which they never provide. I'd personally stay away from them if you have another tuning option (since the Jet chip really isn't a tuning product).
