GIAC Software for the Simos 8.51 ECU in the B8.5 S4/S5 models is nearing completion!

[Austin@GIAC]

http://www.giacusa.com/images/austin/3.0T/B8_5_simos85.png

I’ve seen a bit of buzz around various forums (partly from one of our testers) and wanted to provide everyone with an official update. GIAC is proud to announce that calibrations for the Simos 8.51 have been completed. We are placing the final touches on our in-house flashing and program switching systems. After which, stage 1 software will become available to the public. As with our Simos 8.4 3.0T software, this calibration yields dramatic power gains of 65-70hp and 28-35 ft. /lbs. of torque at the wheels on our tester A7, while retaining smooth and seamless drivability. We should be performing final dyno testing on one of our test S4/S5s in the next couple of days, so I can update this thread with those tests when I have them. I have our A7 dyno tests below in the meantime.

Switching options upon release will include:

91 or 93 octane pump performance mode
100 octane race mode
stock performance mode
valet mode


When released, ECUs will need to be removed and shipped to GIAC for programming. I should have some more formal information. Stay Tuned!

Here are the numbers we saw with our tester A7:

you will be making a lot of people happy with this. Get as many sold as possible before the other tuners get this done :-) great work guys.

[Auditude2.0T]

Awesome tune. I run the tune on my B8 and the car is an animal. Very similar performance to Revo Stage 1 and APR Stage 2 V2.

[well_armed]

Looks like you have solved the redline/boost bleed issue with the new cars. Looks awesome!!

[Ray Khan]

Does the B8 software come with Valet mode? Mine doesn't seem to go to that program. Sorry to threadjack.

More on that very shortly for the Simos 8.4 folks.

[ENV²]

Wow! GIAC ahead of APR this time? Must be cause APR has tons on their plate with the new V8Ts, RS5, Stage 3 for us, Stage 4 for TTRS, etc etc etc

But nice at least the B8.5 guys can do something with their ECUs now.

[madmadS4]

Awesome.

I think GIAC's method is more hack (bypass security), less brute force (trying every possible code to break in) which makes it quicker. This is speculation of mine though based on what I saw when I got chip'd.

Looking forward to the pulley also!

We support Porsche and BMW as well as the new VW/Audi models who are all bombarding us with new ECUs (think new F30 2.0T, 2 new N55 ECUs, N63 twin turbo V8 family which has 3 different ECU types, for porsche 991, cayenne TDI, etc...), so I don't believe that is the case. We are very familiar with Siemens ECU families and that alone was what made this one relatively straight forward for us. It's the beauty of developing all of our own flashing tools in-house. It was keeps us the only software company supporting both Panamera and Cayenne Turbos (both siemens DMEs) with software for almost 2 years now (some companies flash in Panamera Turbo S software into Non-S vehicles which isn't a true aftermarket flash).

We don't hack ECUs as that is technically illegal. The fashion in which we program these is perfectly legal.

[well_armed]

I believe the legal term is reverse engineer.

[MrFunk]

Great news! & Congratulations! First to market is a huge advantage on other tuners. With no ETA from competitors you have the entire market of B8.5 owners who are anxious to get tuned!

GOOD NEWS, EVERYONE

I'm 100% in once available!!! Awesome news.

[jfabes]

why is the power so much lower than the giac published graphs (in the 390's) for the tune when it was released for the B8? is it because of the new ecu? or because its an A7? Or will the B8.5 tune be different? or is this part of the "variability" you get with dynos, cars, etc? just curious.

[Austin@GIAC]

Sure, if what you were trying to reverse engineer had bank strength encryption on every facet that you couldn't hack or crack.

This is a 100% factory stock car with a tiptronic transmission that shifts at 6200 RPMs. Apples and Oranges comparison. The calibration for this car is the same as Simos 8.4 cars.

The A7 is rated at 310hp stock (S4= 333).

Great news!

Do you think tune will be available at your European dealers around Cristmas time? What about pulley/Stage II?

Also, can you do something with B8.5 short-shifting at 6300-6400? I guess power will be significantly lower with this short-shifts, should be very like the posted A7 graph?
Maybe, even smaller pulley that can spin supercharger to its max already at 6500?

Ditto, any changes in systems like transmission response, speed limiter removal and launch control rpms ?

Oh and does it work with the older GIAC flashloader ?

On site flashing is significantly more complicated with this platform, so I cannot confirm that we will have on-site available by then.

All shifting points are ultimately set by the transmission itself, not the ECU. Adjusting those items would require a flash to the DSG's mechatronic. Further, the gearing in the B8.5 is longer than the B8. At 6800 RPM, we see about 108mph on a B8, while the B8 tops out at almost 119 mph at 6200 RPM.

Stage 2 software for this platform will become available as soon as the stage 2 software is released for Simos 8.4.

[adamkb26]

Wow that's awesome! I just moved to the Indianapolis area. Can you tell me the closest best place to get this done when it's available?

The A7 hits redline at 6200 RPM which comined with the extra drive train losses from the conventional auto explain the difference.

Also interesting is Austin's note that the gearing in the B8.5 is longer. I'm interested to see the gear ratios; longer gears may help 0-60 if it allows only 1 shift to get there but will hurt trap speed and ET on a 1/4 mile.

[AwdPwns]

All the other tuners reaction that they didnt get to this first.....

besides that thats sick! i gotta get my b8 tuned soon....

[autoluxe]

So excited for this...look like i'll be saving up over winter lol stage 2 at the same time, as well?? :D

[QuattroLife]

..You guys have been very quiet about this. Awesome job! Super interested in Stage 2 software and dyno plots. We've been waiting for a very longgggg time.

Btw, I was roaming the "other" forum and saw this with GIAC A7's beta tester..


I wanted to let you know I tested my car against a friend's c63 today, I literally destroyed him in every single run, like 2-3 lenghts, the most when standing still, it was more close when we did it from rolling like around 30mph but still the Audi won every single time, I could see the c63 approaching little by little like above 80-100mph, I guess the v8 power is more noticeable in higher speeds, but still no contest there, I was really surprised, my friend tried with paddles, in sport, sport plus, and nothing no contest.
The A7 with the Giac is really really fast, the guy at the shop tested it yesterday and he said it pulls harder than any s4-s5 he has chipped with Stasis.

Freakin win.

[jfabes]

^^^I would literally have to be in the C63 to believe this. Stage 2+ S4's aren't walking C63's (maybe barely beating) and they put down way more power to the wheels than these graphs and are lighter than an A7. it would take a whole lot more than a tune to get that big heavy sedan-hatchback to pull on a stock C63.

Heh, yeah when I read it I was like wtf? That's insane..especially with the A7 weighing 600 pounds more than the C63. Then again I'd refer to Auditude's post above..


Awesome tune. I run the tune on my B8 and the car is an animal. Very similar performance to Revo Stage 1 and APR Stage 2 V2.

It's tough to judge though since both cars are both automatic and that the C63 tried multiple methods (paddles, sport, etc.).

[Austin@GIAC]

I won't be telling people that they will instantly be crushing C63s with a flash. However, our dyno is much more conservative than most. So I don't know that sheer numbers are going to tell the story.

[htoudiee]

I'm super excited! [cool]

[EVO2MAD]

What do you meen, what gen b8,5 or b8 faster with your tune? And top speed?

[Wah]

Great news for B8.5 owners and quite an impressive jump in hp but tq numbers are quite low imo.

[BzzzBom]

Great news from GIAC - I hope we will be hearing from APR and Revo soon. As soon as I can compare the efficacy, safety and cost of the comparative tunes, I will jump in.

[AQuattro]

tq numbers are quite low imo.

Why do you say that? GIAC is achieving a gain of almost 10%. I haven't seen better from anyone else without a pulley upgrade. Am I missing something?

[Austin@GIAC]

The blower is at 100% everywhere so additional torque would need to be made through other avenues. I don't find that to be a low torque gain on 91 octane fuel (95 RON), though. 93 octane torque gains will be higher than that.

The performance calibration we use for the B8.5 is the same as what is in the Simos 8.4 S4s. What you see now is what you will eventually get.

I'm running the GIAC tune on my B8 and have been extremely satisfied with it. The car is strong as hell, and hasn't had a single hiccup. In fact, every tech that has worked on it has mentioned just how much faster it feels than any other B8 they have driven.

[Vi112]

What do you meen, what gen b8,5 or b8 faster with your tune? And top speed?

So, Austin, do you have any suggestions here? How these new gear ratios and shift points can affect acceleration? Maybe you have already tried to (or plan to) compare tuned B8 with tuned B8.5?

[richib86]

the diff gear ratios have me interested... im dreaming of a gear swap... longer gears plus higher redline in the b8 could be pretty good

Would a different weight, transmission, and gear ratio be the cause of this then? [:p]

We saw that GIAC's dyno of the B8 S4 have a baseline of about 306 awhp. This A7 is dyno'ing at 281 awhp. ~25 awhp difference there just with the baseline runs. That difference is definitely shown in the delta throughout the entire powerband.

I'd wait for a B8.5 baseline and tune delta. Nevertheless, the numbers are still impressive and can only serve as a preview to us as what's to come in the near future.

[helix139]

Is the gearing different in the 6MTs or just the DSGs? Is it the final drive gear or the transmission gears themselves?

Austin - can you confirm that the gearing you are seeing on the 2013 S4 test mule is showing longer gearing for the 2013 over a 2012. The comparisons' are both similarily equipped transmissions- right? Manual 2012 vs. manual 2013? You mention that the test mule is an A7, so wanted to check. Audi shows the same gears for 2012 vs. 2013 (at least the PDF documents from Audi do). Thanks

Looking forward to the B8.5 tune!

Will you be able to do on site flashing at GIAC? I live near Irvine.

Yup, beta only. Probably waiting for a local 8.5 to show up

I'm guessing you'll do a baseline dyno for the B8.5 S4 before the beta? so we can get an idea of what the new DSG gear ratios and shifts points have done as far as power output and tuning goes?

It's all relative. 0-60 in 4.9s (or less, depending on whose numbers you believe) is a pretty fast car.

Dan...When my late B6 S4 modded like crazy S4 feels stronger than my new 60k plus car... we have a problem. The car does not make quality linear power through all rpm ranges.
ok...down low is ok stock, but this car is simply just flat in way to many spots...which honestly doesnt make it a whole lot of fun to drive. And yes...I have driven Stasis V2 and APR 11 and 12's, and they pull pretty damn hard. Im just getting impatient with this whole tune thing. The car does not support the reported HP claims to my butt dyno any day i drive it.

Guys the giac tune is available for our cars.

I am holding out for a full stage II with pulley kit tune. I don't want to ship my ECU out and not be able to drive my car till its done, then have to redo the tune if/when a pulley kit is released as well. I have a reputable APR tuning shop near me and am hoping to hold out for local flash along with pulley as soon as its available.......

What are our plans well_tuned?

[scrofas5]

I think just st.1 is available for the b8.5 first, ami correct ? Or will they release the st.1 and st.2 with pulley tunes for both at the same time? I'm dying over here, I need some extra grunt in my s5, tune and intake will suffice for now I guess. Hurry up please :(

[well_armed]

I am going stasis stage 1 until the warranty is out or I get close (ie bored) in mileage.

By then I hope to be in an RS 4 door model, if they ever bring one over.

[QuattroLife]

I was told recently that they're still doing beta testing.

Wouldn't you guys rather have them take their time with the tune rather than rush to release it first and then release a version 2?

Flat is exactly what you want in a torque curve. There is nothing new here with the 2013. We know exactly why the torque drops off and why a tune nets 60+awhp. But if you think a 4000lb car running 12's stock does not support the reported 333hp, you need to do some math. Go to the back of any Road and Track and plot those 1/4 mile traps for a given power to weight ratio. Without ever rolling onto a dyno, it is obvious the 3.0 TFSI is severely underrated.

A $60k car is only as fast as the car you buy. There are plenty of more expensive and slower cars, and you certainly don't have to spend $60k to get a new S4. If you take the original MSRP of your B6, add the cost of your mods, and then adjust for inflation, I would be surprised if it is less than a comparatively equipped B8.5. In fact, the only new sedan I can think of that is both faster and cheaper is an SRT8, and that's probably only possible on a prepped drag strip. Even if you opened it up to coupes, I think you'd only add a base C6, ZL1 and GT500. There isn't a lot of cross-shopping going on there.

I am very curious to see these many new fun things coming to our platform.....anyone have any ideas?

The software is complete, we are just doing some final testing on it. Since these ECUs must be sent in, we chose to allow local customers get the software. This way, any updates could be done on site and would not result in further down time of vehicles while ECUs were shipped back and forth. We could have easily said nothing about it and there would continue to be a constant influx of threads asking "when will a tune be available for the B8.5." Further, we have already released the A6/A7 software which is widely known to be the same ECU family as the B8.5. Questions would have undoubtedly arose since we are selling that software already, so we chose to give everyone an update up front for it.

Based on the feedback I have received on the software, most are patient and excited that they will be able to enjoy their cars with software very soon. It seems being the first to crack the software and offer it can't please everyone, though.

Lastly, you are in L.A, you can come down and get software installed at anytime. Shoot me a PM if you would like to come down.

I'm not currently a customer of ANY tuner as of yet...... just a 2013 B8.5 S4 owner looking for a Stage II with pulley upgrade provider ...... are you my new home? [:D]

The software is complete, we are just doing some final testing on it. Since these ECUs must be sent in, we chose to allow local customers get the software. This way, any updates could be done on site and would not result in further down time of vehicles while ECUs were shipped back and forth. We could have easily said nothing about it and there would continue to be a constant influx of threads asking "when will a tune be available for the B8.5." Further, we have already released the A6/A7 software which is widely known to be the same ECU family as the B8.5. Questions would have undoubtedly arose since we are selling that software already, so we chose to give everyone an update up front for it.

Based on the feedback I have received on the software, most are patient and excited that they will be able to enjoy their cars with software very soon. It seems being the first to crack the software and offer it can't please everyone, though.

Lastly, you are in L.A, you can come down and get software installed at anytime. Shoot me a PM if you would like to come down.


If that is the case, can you please post up a dyno chart for the new B8.5 S4 ECU?

Any dyno results for the B8.5 tune yet? I've had the GIAC flash for about two weeks and it is awesome -- smooth but very fast, especially over 3,000rpm.
