Chevy HHR SS File - Not Supported

[405HP_Z06]

I'm assuming ford and dodge are more important as of now....

More than likely a valid assumption, everyone follows the money.....

[mrphoto103]

So I'm confused... I see the 08 HHR on the support vehicle list now, can we do the HHR turbos or not?

Yes, which is why it was added to our supported vehicles listing.

So results people we got the tune who's done the tune and what results have you gotten

[rommer]

I've done one and the results are "WOW"!

[gcsd3742]

I had to DE-tune mine a bit, too much power...was causing clutch slip at 3k rpm in 4th and 5th

[gcsd3742]

so noticable difference but? what are some of the characterisctics and power advances? meaning what did you really notice? and power wise what did it show and boost?

set mine initially at 21-22 lbs boost, and noticeable, like a brick thru a plate glass window! injector duty rate at 32% lol
not a problem except the clutch, settled the boost at 19-20lbs and all is well, it pulls like a beast!

I'm assuming an M5 because the A4's still aren't supported. What did you change and what kind of boost numbers are you seeing? Can you post your tune?

SS_SC_Cobalt, can you post a log file with your modifications? I would like to check it out.

this was before I turned the boost down, I still get some initial high load knock when the go pedal is first hit. didnt adjust the timing yet.

[405HP_Z06]

HHR 2.0L auto is supported...

Not for tuning, try to license one and see what happens.

Thanks, the tip in knock is most likely burst knock. You were getting the max boost (22.4 psi) for short periods of time in that log. What did your air load tables look like?

[gcsd3742]

so no one else has tuned and can show tune or improvements?

I raised them only 5-10% on the top 3

So what's the latest and greatest on this subject?

The HHR files in question have been supported since September of 2008.

The HHR files in question have been supported since September of 2008.

But the current public build is from april 08, you should really update it a bit more frequently.

We create a new beta on a weekly basis which is pretty frequent IMO, once we feel it is stable enough for public use we will make it public but not UNTIL then.
