Awesome. Incredible. Thrilling. Shall I go on?

I originally bought the HP Tuner package with base tune from Andy about a month ago and it has been a real blast. I've been playing with making some of my own tunes using info I've been learning from books and the HP Tuner forum and I've made a few decent experimental ones. There was always something not quite right when I did it, nothing major but things like poor gas mileage when driving normally or not quick enough boost. All part of my education.

Upgraded to the stage 2 tune he offers and it is incredible. I'm still 100% stock and I do run 93 octane fuel. Time to start putting together the funds for his exhaust....

Nice job Andy!

You will love the exhaust I have the no-cat....added about 25hp and 35ft/lb FTW

Was that just by adding the exhaust? I thought the factory exhaust flowed very well??:confused:

I have the BSR tune....when I added the exhaust I picked up that.

Wow! How loud is it w/o the cat?

yeah sound clip

Your making around 280-290 whp right now and 320 + torque.....It is the best $600.00 you ever spent! :thumb:

I can now officially second his opinion on the Stage II tune. I installed it tonight, and the difference will blow your mind. Second gear is useless at times. It's ridiculous, and I love it.

I want ridiculous power too! More power than traction is fun!

Now that winter is here, I'm driving more in the rain and even stock, 1st gear is truly useless at full throttle, and 2nd gear is pretty much useless too. I like modulating the throttle to get decent acceleration anyhow - it keeps me entertained :)

It is alot more fun that is for sure.Glad to see you got everything going so easily.

I hate you all with 93 Oct. :lol:

Oh now your just being mean. :lol:

Was on the boat all weekend so I didn't use the car till this morning. Every time I step down on the throttle brings a big smile to my face. Pulling out on to the freeway is such a rush!

Been a long time since driving has been this much fun.

Camaro just add in a bottle of NOS and you can do it to...

I'll most likely just swap tunes with 100oct for when I go to the track and they detune it when I normal drive. Im sure they could tune it for 91 oct as well. I also don't think anyone has tried 91 oct with the tune. Yes I know a lower hp will happen but it's still more than stock.

Question for ADM. If a person can't get 93 Octane fuel in there area can they use something like a Snow Boost Cooler and water-methanol injection to help with the lower octane fuel and use your stage 2 tune?

Dennis

Snow Boost Cooler and water-methanol injection

This is my plan.

This is the water/meth injection kit I plan on using. I'm going to try one on the Z06 also.

Exactly what I was going to use. :lol: That should have enough volume to get me by for a week or so...

This is up to the customer.All of our product testing is done here in texas were we run 93 octane.If we did all our testing in a 91 octane state than I would probably have done meth/water injection test as well,but we dont.

If someone buys Hp tuners and our stage 2 tune for $599.00,I would be glad to look at their datalogs to help get them were they ned to be on 91 octane.You must understand that you may not recieve the same power levels we reach on 93 octane.

It's also VERY convenient on long trips.

That being the case if you did have access to 93 Octane and you were using meth/water injection, could the tune be little more aggressive? My thought is that the cooling effect of the meth/water injection would help to cool the charge more than just that of the intercooler depending on where you inject.

Andy, BTW I just got my HP Tuners package from you.. it was waiting for me on my desk.. Now I just need to install your stage 2 tune.... and from all indications, hang on...... :smile: Then I will install the exhaust when it arrives.

Thanks.
Dennis

let us know what you think of the tune and also what exhaust did you get? I want sound clips before and after

It's also VERY convenient on long trips.

Also very 'green', due to the recycling of 'resources'. :p:

I just ordered the Snow 20010 with boost controller and a few other assorted accessories... about $520 landed. I also got a weld-in bung (waiting for the jokes) for my "maybe I'll see one soon" IC hard pipes to pretty up the install. I spoke with Greg, who recommended just plumbing it into the stock washer fluid reservoir... the blue stuff is generally a 70/30 mix of water and alcohol, and if I feel like it, I can toss in their "boost juice," which is about 50/50 mix and just have an expensive windshield washer fluid to boot (about $7/gallon). I'll start with straight washer fluid for now... :eek:

Where you going to put the pump?

What do you recommend as an after market clutch for this car?

Definitely going to need one.

here's your answer: Clutchmasters already has a setup for it.

I went to their website and it doesn't list an application for the HHR SS.

what kind of boost are you seeing with this stage II tune?

what kind of boost are you seeing with this stage II tune?

20-22lbs. on average.

Keep in mind the most the PCM can currently control is an altitude corrected 22.5 psi.

Is that because of sensor?

D.

Nope, they use an 8 bit value to represent the manifold pressure which can only go to 255. Without going thru the math I've seen others use at HP Tuners that equals roughly 22.5lbs of boost.

This is suppose to change with the pending release of the GM stage kit but we shall see.

From that my guess is that the D - A converter used to read that input is an 8 Bit converter but the scaling is such that when you see 255 or 0 that equals 22.5lbs of boost. If that table is rescaled you can make those values read whatever you want, Although I don't see a table in HP tuners to allow a person to do that unless I'm missing it.

An 8 bit D - A is generally a chip that is soldered to a board, to get the resolution any better one would have to change the chip. If GM is changing the highest value that PCM to something higher. Are they intending to change the PCM and the sensor, or, just changing the sensor and rescaling the output value?

Interesting

Leaks indicate it's a register shift. Maybe somethng like these get support...

We'll take the .1 to 3.5 Bar please.

I can believe a shift or a shift with math but they would still have to rescale the table/s and again they have access to tables we aren't seeing with HP Tuner, yet.

Load could be calculated from the map sensor, 100% load could be 0 PSI or 14.7 absolute and 200% could be the highest value the PCM can read from the A -D but it would still need to go into some sort of table I would think.

Don't know enough about this PCM, Yet.

Agreed on the scaling. 3.5 bar... wheeeee. I'm not planning 50psi, but 30 sounds good :bow:

Re the scaling, it's pretty clear they will have had to do something big, and again, leaks from inside are saying this is an OS rewrite.

That doesn't sound good. Wouldn't that make HPT useless until they can catch up?

Yes.

Not for me. Only for those that choose to buy the Chevy tune. Which while having some interesting possibilities will initially have less HP and torque then the current OS tuned via the HPT system.

Hopefully HPT will be able to open the new OS as well and allow things to proceed even farther.

rommer I agree. I am currently running an ADM Stage 2 tune. If the numbers being thrown around are correct I would be going backwards. Like you, I believe I'm going to wait until HPT is able to open the new OS before I consider moving in that direction.

My biggest issue at this point is getting the power to the ground.

Between smoking the tires in 1st and 2nd and occasional clutch slipping the last thing I need right now is more boost!

I don't have the clutch slipping issue, yet.... But I do have a traction issue. As I see it, if we fix the traction issue, the clutch will be the next problem. After that maybe the trans. Tires are a given at this point.

XXL, have you installed your snow injection system yet?

The immediate topic was with regard to the GM stage tune OS. But, of course, you new that when you posted, oh great one.

I just finished installing the stage II and 3’ exhaust combo from ADM Performance. The power is amazing. I went with magnaflow muffler. The sound from the 3" exhaust is nice. The HHR is still quiet enough to be on the phone with a customer while driving down the freeway. (bluetooth headset) That being said with a WOT it can be heard. The exhaust tucks in just like the stock exhaust. I have seen many after market exhaust hanging out from the bottom of cars dragging over every bump in the road. I was also able to make sure the pipes are not banging on the under side of the car. This is a nice fit. Two thumbs up on a job well done.

I am hoping to go to the track this weekend and get a time slip or two.
