Come on, educate us! HPTuners doesn't come with directions for tuning a Cobalt so give us the low-down on spark timing, A/F ratios...you know, all the details. I've also read posts where a Cobalt owner let someone "else" (knowledgable tuner?) tune their Cobalt and ended up having to take it back to the dealer to get it reflashed so it would run -- so let us know how to reset the ECM in case that happens too.

This is an alternative to "tuning". Besides, it's not so easy to tune your own car and the cost is a heck of a lot higher for everything you need to start out with HPTuners. Do you have HPTuners or do you just not have anything constructive to post? If you do have HPTuners start a post that informs others on what you need and how to do it. I am tired of posters saying "a tune is better" -- when 99.9% don't even no what they're talking about.

well if your lack of tuning experience shadows over your pathetic dream for a tuner car than maybe that ebay chip is right for that can you call a car. grow some fking balls and have some self respect. you should have just bought a early 90's civic hatchback...it would suit you better

Just what I thought...you don't have a clue. This module (NOT A CHIP) is for the average owner who doesn't know how to tune or doesn't know anyone that can provide a tune.

Tuning an ECM-controlled car isn't the same as opening or closing the gap on a set of points. No one has published a real how-to on this either -- from what you need to make it happen like part numbers, cables, etc to what changes you need to make --AND DON'T MAKE! I listen to the woes of others with interest -- like the individual that got his Cobalt tuned and it wouldn't start. The guy that did the tuning thought he knew what he was doing to. It is not impossible but neither is it simple.

the shit you see on ebay are resisters not a module that jet chip sells.Which I am sure of it that you already know that pcm and ecu is the same thing just worded different.

Technically, and IAW the 06 and 07 Factory Cobalt Service Manuals, the 2.2s and 2.4s have an ECM while the 2.0 has a PCM... I didn't write them....LOL! ECM = Engine control Module; PCM = Power control module. My guess is the name difference is the control of the SC, intake cooling system control, etc.

[burzumaske20]

yeah there isn't a difference of what they do, just different names lol,but from what I heard that power control module was said before they decided to say other names like ecu or ecm.

I think the moral of that story is to pick someone who knows how to tune and can prove it rather then someone you think knows how to tune. Also alot of the start up issues I've heard are not due to tuning but more over some set up problem. As a tuner you should NEVER tweak a car to the point it won't start and I don't understand how it would get that far. The idea behind tuning is to make very small changes that are steps in the direction of the tuning goal rather then one large final step.

A good tune takes hours, not minutes.

As for writing a how to on tuning, you aren't getting one from me. I know how to tune but it has taken me about two years to learn how to do it confidently. I can't summarize that in a post or two. Plus it requires a rock solid knowledge of engine theory so there's another books worth of posts.

Couple all that with the fact that I sure the hell am not going to be responsible for someone blowing up their engine because they read a how to I wrote on the internet and thought they could tune so they dove right in.

The fact remains, there is no substitute for a custom tune for a car. No chip, module, or whatever you want to call it can give you what a good tuning suite will.

We're all aware of that, but wouldn't you rather us buy a chip for a small gain than do something stupid trying to get a large gain?

Nobody here is arguing the advantages of a tuning suite like HP, we're just saying that the module is the best we can do with our limited knowledge.

[burzumaske20]

I would have to agree with BlackBaltSS,not everyone has the knowledge of tuning their cars.If hp-tuner actually was coming out with a tune for the 2.2,I would go with the hp-tuner route,but since they're not doing shit for it,I might as well go with the jetchip.

I know you guys know that, it's just these modules just make me a little nervous. I realize, or I hope anyway, they have tested these out on a cobalt but it's sort of like throwing darts at a dart board and saying well that's the number we will put in this cell and hoping it works for your car.

It's really risky IMO, but I wish you guys the best of luck.

Your post above about what it takes to tune is logical. Tuning these ECMs/PCMs is neither easy nor cost effective -- I looked into getting the HPTuners and a laptop and the amount of money it would take and with the lack of written available knowledge just wasn't how I wanted to progress. This Jet Chip module is working for me. Just the increased off-the-line wheel spin tells me that it is producing more HP. I think they did test this on a Cobalt because it is working on my 2.4 -- and nicely I might add!

I also had experience with Jet Chip proms in the 80s on GNs and T-Types AND I had a nice discussion with 3 Buick Electrical engineers about the proms. I asked them why Buick couldn't produce a performance prom instead of Jet Chips and they told me they were bound by GM management and federal emissions requirements -- even they agreed that the Jet Chip proms were providing increased performance -- this was while at Beach Bend International Raceway racing Buicks and watching other GNs and T-Types going down the dragstrip.

Simply put I provided information on a product available for Cobalt owners. They can choose whether they want it or not. I doubt the average Noob Cobalt owner could pick up HPTuners and know what to do with it.
