Just a note. Before you look into your expensive Supercharger or Turbo app please be aware that no one yet has been able to crack the 2.2's ECU and therefore are NO tuning option available. The HHR stock ECM cannot read positive manifold pressure (IE boost) and will put your HHR into "limp" mode if you attempt this.

There is ONE exception. If you have a 2007 HHR with the new 2.2 Ecotec ECM which is identified as having a coil-on-plug ignition system you are lucky. These engines can be tuned by HPTuners. Changing an 06 2.2 to and 07 2.2 is VERY costly and not worth the trouble.

For those INTENT on getting forced induction you would have to convert your HHR to a stand-alone management system like Megasquirt etc... They are also costly and require a LOT of knowledge for Fuel Mapping, Ignition timing, MAP sensor readings, and general engine management. This is not for the average shade tree mechanic. Although there is a LOT you can do with one such system please do your research and find one that is good for you.

I hope this info is useful to some that come in and anyone that has anything to add please feel free to do so. I am just trying to make sure people don't get their hopes up with advertised "bolt on" applications for Turbos/Superchargers for these awesome autos!

EDIT:: Piggy backing systems may work on the 2.2 since it doesn't actually edit the HHR ECM coding. These kinds of systems do just what they say, they ride the back of your ECM and CHANGE what the ECM "sees" to make the ECM put out more fuel or possibly "hide" a positive manifold pressure (boost).

Apex'i AFC setups DO NOT work on the ECM for ANY of the newer ecotecs. 2.0/2.2/2.4

Very helpful info Jason...but I have no plans on force feeding my "Smoke". I'm happy with my HHR the way it is and have done enough performance mods to keep me happy. Thanks for the info...I'm sure there are others who might be thinking about souping up their 2.2's. :thumb:

so does this mean that speedmafia's piggy back set up doesn't work? i mean they claim it to work on the ion,

Deb.. I posted this since I have seen a LOT of posts on turbo/supercharging setups that people want to try. Like using the Cobalt SS Supercharger on a 2.2.

UpOnGaMe.. See edit above.. Thanks for pointing that out. I would like to make it a sticky that way it stays on top and people can refer to it for any questions they may have.

The only reason I have learned a lot on this subject is because of my addiction to boost. I need to force feed my HHR one day! Or get a SS when they come out! :D

do we even have stickys about performance, like the famous which intake is better? there should be one on that saying SEARCH n do your own research

Written by Halfcent:::::
That's right folks, the 2005-2007 Chevy Cobalt 2.2L L61 cars with the E16 ECM is FINALLY going to be getting some tuning! SCT was contracted by Garrett to create a packaged flash tune for their upcoming turbo kit release in the first quarter of 2007. As a result, SCT will also be able to incorporate the ECM hack into their regular custom tuning software called "Advantage 3.0".


http://www.sctflash.com/

Advantage work exactly like HP Tuners does. But they have one additional option that is pretty cool. Once a shop gets a custom tune made for your vehicle, they don't just flash your car and send you on your way. They upload the tune into their device called the LiveWire. It can store up to 3 different tunes, so say a stock tune, your boosted road tune, and your race tune. Then you can switch between those tunes, on the fly, in your car, whenever you want! On top of that, the LiveWire is an OBD2 device with analog inputs, datalogging, and real time data display! It's just too damn cool.

Now I haven't confirmed yet, but I believe you can buy the Advantage software package for yourself as well, just like you could buy the full the HP Tuner software package. Then you can do your own tuning outside of the shop whenever you wanted.



This is good news to ANYONE wanting to get anything better from the 2.2 engine.

When is your kit going to be available for purchase? Have you tested this on an HHR? Will all the plumbing work with the curves on the HHR? Inquiring minds want to know.

I repeat the above request...^^^^^^^^^:thumb:

Also; - it has not yet been verified that the Cobalt and HHR share the exact same ECM. Even if the module is the same, the OS code could be different. We have heard from people who build SEMA cars for GM that could not sucessfully boost an HHR. Some proof of HHR compatability would be nice. Thanks! :thumb:

good thing I have a 2007 with the 2.2 Ecotec!

the ecm's are different from the HHR and cobalt

different settings, different BCM's as well

we are still waiting on finishing our tune with our supercharged hhr

its on the car and functional

we used the cavalier 2.2 GM supercharger package.. only thing different were injectors and had to make new line for A/C

we wont get a chance to tune ours for another month or 2 because of the vehicle needing to be at autoshows all over the country.

I have the )& 2.2 can you send me the info for the hp tuner setup?

Check with CobaltSS.net. No one on this board has done a HPTuned 2.2 yet. Or check with hptuners' website. They may have some usefull info there! :twothumbs

HI GUys I have the 07 2.2 also automatic any body have someone that can tune it for me i am looking to get the stage 3 cam and the tune and forget about forced induction. maybe later i will trade up to the turbo and give my son this one

just fyi checked with tune tyme and hp tuners nothing for 2.2 hhr no matter the year.so i will probably go stage 3 cam supposedly it doesnt need a tune and the header. i already have the cgs intake and the turbo muffler

Please realize I'm not knocking anyone's just I guess I'm asking for opinions from 2.2 owners........:smile:

Why get the 2.2 and not the 2.4 if you plan on performance mods? I just think it would make sense to START with an extra 30hp. People are doing intake, exhaust and other thing and still haven't gotten to what the 2.4 does stock.

With the same mods PLUS a tune, I've got my 2.4 over HP. Its gonna take a bit to get a 2.2 to that level.

Again, I'm not bashing, just thinking out loud.:thumb:

I (my wife) didn`t buy the HHR with speed in mind, but the engine that would accomodate a supercharger is most likely a 2.2L .

That is exactly correct, i don't have any plans to force feed my HHR any time soon but its nice to know that i can. Plus i don't really like the VVT, you are alot more limited by it than you are helped, i just don't want a car with lag that doesn't have a turbo.

The VVT system isn't "lagged" like a VTEC system would be. The way the VVT system works is completely different. VVT is active ALL the time. All it does is adv/ret the cams to get better performance. NOTHING like VTEC. You would actually see MORE gains from force feeding the 2.4 than the 2.2 since the engine will adjust the cams accordingly!

Okay, so again.....why a 2.2 and not a 2.4? Why 140hp not 170hp?

I started a thread a couple days ago, "Why I bought my HHR", (38) respondents at this time, no one said they bought their ride for "Performance".
I got it because it was "COOL", not "HOT" as in hot rod.
2.2L vs 2.4L please, give me a break. It`s a grocery getter for goodness sakes. Guys standing around an HHR wondering how many "Horses", Ha.
Even with a Turbo/Super Charger, who would take you seriously.

Dude lay off, i don't go into the threads talking about the new fake chrome pieces that in my opinion make the car look terrible, but then again it is my opinion. What some one wants to do to their own car is their choice. My last car was a 91 caprice wagon that came with a 305 TBI and i put a 350 TBI into it, why when the 94-96 caprices had the LT1 and were alot more powerful than the 91-93's even after i did the engine swap. It was because i wanted to and i loved that wagon. Plus if you smoke a civic in either an HHR or a Cobalt, what has a better cool factor. You better believe the HHR. Every one loves a Sleeper.

rant over.

Hey, sorry DUDE, still no change in opinion poll, you could`ve made a difference.
Maybe led taillights improve the looks and performance more than chrome... B/B

I didn't buy it b/c it was a performance machine, i just fell in love with the looks the first time i saw it. I would just like to improve on my HHR in any ways that i possibly can to make it more my own. Things like LED tails that come on faster and give you less of a change of getting rear ended, better braking also for safty, more power to make the car more fun to drive, each of these things are also personal preference, and that is also what makes owning a car not just another thing to own but a hobby to enjoy, to each their own.

Cool, just didn`t want you to take anything I said personally.
We all have our own taste, but we post because that`s what this is, a friendly discussion.

This is how I'm going to force feed mine.....lol....I still have to finish running the purge line to where I want it, get the bottle filled, and I need to get fuel and nitrous gauges just to be on the safe side........Stay Tuned

You know its these kinds of posts that really "irk" me about some of the people on this site. I personally bought the HHR for the wagon body style and also the performance! Check with ANY other company offering a wagon and check the performance numbers. The HHR is 10x's better for the price in looks and performance bar none! 2.2 OR 2.4 it doesn't matter. I mod my car for me, not you. I dont talk about the cheesy chrome crap on other's HHR's that turns me off to the looks. Simplicity in design. My HHR to me is just that! No extra chrome crap. The only thing truly "show-y" on my HHR are the 20" chrome wheels. Everything else is clean, simple and for the most part makes it faster. My HHR in its current state is running faster than ANY STOCK 2.4 HHR out there! Just because my time slips at the strip don't reflect that doesn't mean it's not. It just means I can't drive at a track. I get too ancy! ;)

The purpose of these vehicles is to modify them to YOUR liking. We are here to help eachother out and not talk crap about what someone chooses to do with their HHR!

I don't, haven't and never will vote for your HHR because since you have been around I haven't heard much from you in a positive manner BB. The nicest thing I have heard from you was during the HHR of the month contest which you ran against me but were a little confused as to the votes. Then when you took the time to see someone else's auto you realized what was done to my HHR. Your response was "Next time let a guy know he's coming to a gun fight with a knife." It was the nicest thing i've seen you post about another HHR other than yours. If people want to add performance then let them. You don't like then DONT POST. It's quite simple.

Now if you want to start a thread about pointless chrome rub strips lining every possible naked edge of your HHR then great! But don't trash talk asking if anyone would take you seriously about performance on a HHR. Truth be told the majority of the people in Tucson AND Phoenix here in AZ that I have raced are VERY impressed with the HHR I have and what it can do when opened up! On the strip I have run consitant 16.9's regardless of what I've done to the HHR. However on the street when we're playing around I am hanging with and beating cars running mid 15 second quarter miles. It just means they are a little more calm than I at a track. So please keep your negative comments to yourself because you're not helping anyone!

Rant ended... We now return you to your regularly scheduled thread....:nuts:

Sorry, I didn`t mean to upset you so. Thought I could post as you can, guess your opinion is more valued.
If I had said some of this kind of stuff, all positive I might add, I would`ve be censured.
I do see (1) vote for performance, must be you...
Some guys just can`t take a compliment. B/B

Sure you can post anything you want as long as its not OFF TOPIC. If you want to make a thread about how crappy the performance aspect of the HHR is then do it. But don't come into an informative thread for people wanting something more than Chevy gave us and talk crap or step on peoples toes. I don't care if anyone takes me seriously even if I have a turbo or SC on my HHR. Its for me and what I want. Now, stop your crap and make your own "performance bashing" thread. Thanks!

Wow Rude that looks sweet !!! Keep us updated on how it works...way too cool !!! I can't wait to hear it kick in during a cruise...well I guess I would only hear it for a second as you blast by me, but that works...hahaha

Thanks Pat....... I hope to have everything completely dialed in by the QC meet. I would really like to get some track time in and see what kind of times it will turn with all the mods.....I'm hoping to get the bottle filled up tomorrow afternoon, and I'll just toy around a little (if weather permits). I'm keeping my fingers crossed. If not this weekend, there is always next weekend....Regards
