I ordered mine... but they are supposed to send an email to me first I believe.

I haven't gotten the email yet. I did call an hour before closing on Friday though...

How long did it take you all to get an email?
I'm just excited to get this going. Other than a drop in K&N this is all that I plan to do. Although once I get bit by that bug.. you know. I'll run into a car that's just a lil bit faster and have to do something else. Way it always goes....

How much is this Tune?

Psykostevo

The Hahn PPC is $995

I got my email from hahn the next day, and it was a form to fill out, as they need your VIN to program the PPC to your car before they ship it out to you.



BTW, I have had it on the car for over a week, no issues at all and no drop in fuel econ.

Psykostevo

I should say that there is NO WAY to make the fuel economy worse on these cars when not under boost. The car commands it's own AFR, so you're golden. Obviously if you drive under boost often your MPG will go down, but nobody should be doing that all the time.

Its saturday where is the dyno run???????????

so you can buy the tuner once, and do unlimited flashes?

Zander916

Back and forth from the stock tune to the Hahns tune on the same car.

But not multiple cars...

i dont know anything about tuning is it a bad idea to buy hp tuners

hatrickstu

hmmm, so how much does it cost per car? how is psyko doing this for $300 a piece if its only 1 car per tuner

yes because you know nothing about tuning

duke3323

not going to hijack this thread, use the search button

hahn tuner is one car per tune

psyko has HP tuners so he can tune as many cars as he wants

OH gotcha, it all makes sense now

Boost is not that high in first gear for obvious reasons. I just got my PPC, The tq is monsterous in second and third, even 4th gear from a low speed\low rpm, the car just responds RIGHT NOW! Hahn is also in a much warmer area Jolkiet, Ill with higher humidity than most of ontario other than the southern parts, and still much cooler at night there in CAN to. The 3 tack elevatios are all within 300 feet of one another in Ontario, and close to the one in Ill.

One thing I did notice, while doing a top speed test run on a closed runway at the AFB is that the car seems to run out of steam at about 135, and from then on it goes real, real slow. A friend with GM confirmed that the car is governed at 142 or so. That explains why it seemed to not go much faster, or maybe the PPC lowered the top end by improving on the bottom? Either way the car hits a brick wall, slowly at about 140.

The auto mags say drag limited to 160 and with the big high wing it's limited by drag to 147 . I have the small spoiler\wing . I would not take the auto mags word for much these days.

My car before PPC in 100* air, track is 1240' and a DA of 4479' with unusually low pressure of: 29.66 ran a 14.10 at 101 mph >>> 100% stock. After the PPC in almost identiacl weather, 13.49 at 106.88 mph. Nice! Now I need traction as it does not exsist in first gear even at 75% throttle, and spinning wheels in the 1-2 transition. A rep for Mickey Thompson was at the track and came over to me and gave me his card. He stop-watched my wheel spin: I'm wasting nearly 8 tenths of a second (nearly one full second) spinning the tires. I'm calling him monday.

This PPC has two stages to it as bolt-ons get made and or the tubo is upgraded. Free software updates at the BSR web site too. BSR is the worlds formost leader in tuning of turbo charged cars. I've had their products on some of my cars from 15 years ago.

jerrodmann

13.49 just on a tune? thats sick! do you have the scans of the runs to post on here? awesome...

glhs379

Great times!


almost 107mph in almost 5k DA.

That's flying!

Need to get mine to the track.

Zander916

Do you recall at what RPM it's at in 5th at 140ish? Looking at the power curve on Hahns site if it's just over 5K then the max hp is reached.

My Acura RSX with roughly 35-40 less hp (after mods) would do 148ish. So maybe just gearing where the hp max is. Certainly my new SS/TC would kill it in the 1/4 though.

Not a big deal I guess as I'm sure most of us don't have a need to be going those speeds anyway.

13.49 while spinning.. good numbers man.. im still debating on just getting tuned by hp tuners or buying the tuner

If i do purchase the Hahn tuners or HPT and i need to bring my car in for service, does this void my powertrain warranty or will they not be able to trace it back? thanks

Zander916

I can't imagine it NOT voiding your warranty.

You can very easily flash it back to stock before you take it in. If they were just absolutely dead set on finding out if it was reflashed before I'm sure they have ways. But I'm sure they don't just go around checking that stuff either even if they do have that capability.

As mentioned they are two different tuning methods. Hahn is selling the BSR PPC flash device that comes pre-loaded with a tune that BSR develops. BSR doesn't offer the end user the ability to custom create tunes. I may have missed it, but I haven't seen if Hahn had them customize any parameters for the unit Hahn is selling. I'd suspect it's the same tune they developed for the Kappa roadsters (they are primarily a European tuning company and we can probably thank GM for using a Bosch engine controller like many European marques use and for the Opel GT using the LNF engine as to why we get supported). You can find more info on BSR's web site at this link. The other tuning option most private individuals and tuning shops are using is HP Tuners. It allows an owner or private tuner to custom develop tunes (unlike BSR which is programmed and you get tunes developed by them). There's a few different options for HP Tuners and you can find more info here and here. With either method most of the cost you're paying is for the actual tune and the time, effort, and development work that went into it. With BSR you're getting the convenience of the handheld flasher and extensive dyno and road testing they do to ensure their tune is safe on all vehicles. The HP Tuners pricing will depend on what options you're buying and who you're buying from. If you want to buy the full suite to tune your car for yourself it will be more expensive than paying someone who's bought the support for your vehicle and can provide you just a tune. It's kind of an economies of scale which is why he can provide you a less expensive product. Both options are just tools to alter the calibration/tune (i.e. programming) the stock computer uses and may accomplish the exact same results. If you do go with an HP Tuners solution remember the quality of the tune to include the drivability, safety, and power it provides will depend on who developed it. Is it technically possible to tell if you had an aftermarket tune installed? Currently with both solutions the answer is yes. Will the dealer check for this if you take your car in for service? It depends on the dealer and what went wrong. If your air conditioning or radio stops working most dealers probably aren't going to be looking for a custom tune. But if you have a cold air intake, giant exhaust, bigger intercooler and show up with a blown engine they do have the ability to verify a calibration verification code using the Tech 2 scan tool. It's all going to depend on what (if anything) breaks and your dealer. There was a TSB (technical service bulletin) GM released a while back that tells how a dealer should check to see if an aftermarket tune was installed. I think it's been posted here on the forums and you should also be able to find it out on the internet.

Are there any negatives to the PPC so far? It seems like people who have it are 100% satisfied. What does the butt dyno feel from stock to PPC?
