Welcome to the world of a poorly selected turbo size for the engine. One friend of mines Cobalt SS that I tuned went through a few iterations.

I hit the dyno and found my tune was producing a lot of low end tq, but in the upper end it pretty much reverted to stock settings. I haven't had time to figure out what the issue is with my tune...
If you need an 07 I can provide it. Also GM stage 2 files if you have those injectors.
xxprotegexx, does your cruise control still work or is that not working as well?
How is the clutch holding up on the pulls with that Tq spike? I used to find that a slipping clutch will quite often give you false knock. I didn't see a loop-loop on the graph for a fully slipping...
Same thing happened on my 07 right before my lease was over. Electrical gremlims. Since I had warranty I left it at the dealership for 3 weeks (my friend was a service advisor). They couldn't...
Make sure the OS matches the engine you are building it for. When you read the tune from the PCM it will tell you the year/engine size/OS that is installed on it. If its not what you are expecting...
I am also glad to hear they were able to fix it for you! Makes me less scared everytime I hit write....
When they unlocked mine for me through a support ticket, they first wanted to see a picture of the label on the PCM. From that they instructed me what to use for scanning it.
I am betting not...
Spend the credits and license a file for the correct year of cobalt SS you are tuning, and do a write entire of it over the solstice file. What MAP sensors are on the car, factory or the 3bar from...
HPTuners, why do we have to be on the internet to flash basically any vehicle that requires the MPVI v2? This is very inconvenient, as most times this requires hotspotting to a cel phone, which...
Did they ever help you with the issue?
Working with HPT to get this working better. Right now it still reads in the VCM scanner as the wrong vehicle and is missing a lot of needed PIDS (knock retard for example).
But I have started...
Trd, can you please look at this log file?

Thanks Bill, I will do that shortly.
Since you already support the Hyundai Veloster with the same 1.6l engine, will support be added for the Kia Forte with the same engine (coupe and hatcback versions have that engine option).
Thank...
Laser racer has the right idea with that tune, the enrichment rate (in the fuel tables, PE tab) is causing your problem. With it as low as it is in the stock tune, it takes forever for the computer...
Read it, and gave me the option to license it, I did not receive the invalid os/vin message so it looks like an 08 2.2 HHR is supported.
Kevin
Guess that's what I will do :)
My beta is a couple of months old, so I will request the latest from Bill.
Will update this thread when I find out.
Kevin
I know the main page doesn't list it, but its not always up to date.
I figured since there is 07+ 2.2 Cobalt support I would ask.
Kevin
Working on it today, I will try going back to pressure mode and using hte constant. Forgot we had that now actually, glad Tom brought it up.
The overlay isnt needed with the extra options, but...
Spoke to Vince before tuning this car, and he told be that the fuel changes from HP tuners would be effective, that I could put it in fuel mass mode, change pressure, ect.
Trims are close now,...
I forget exactly what size factory LSJ injectors are, but just download a stock LSJ tune (not staged, they have 42 lb injectors), and you have some injector values to work with. You may have to...
I just saw your last post that you read it with a 2.23 beta. Which build is it? Last I heard the 2.2s were only going to be added to 2.24.
Kevin
2.2 Cobalts are not supported in 2.23, only 07 + 2.2s in the 2.24 beta are supported. I am not sure how stable that release is yet. They will be supported in the future official release, but aren't...
