Unitronic Performance Software & Pulley Upgrade for 3.0 TFSI

[Steve@Unitronic]

Unitronic is pleased to present its Performance Software and Supercharger Pulley Upgrade for the 3.0 TFSI® engine platform found in the B8/B8.5 S4®/S5®, C7 A6®/A7® and 8R Q5®/SQ5® chassis. Unitronic precisely recalibrated the SIMOS 8.4/8.5 engine control unit (ECU) for maximum performance, reliability, and drivability.

With baseline figures and data collected, Unitronic interprets the data and adjusts the engine control parameters for optimal performance. Research and development of Unitronic’s Performance Software continues with further dyno and track testing, while closely monitoring running conditions through live high-speed data logging tools, and further optmizations are made to ensure maximum performance is achieved, while maintaining complete OEM-like reliability and drivability; increasing throttle response, and improving overall fuel efficiency*.

Unitronic’s Performance Software is programmable directly through the OBD-2 port and within minutes you’ll be enjoying a total night-and-day driving experience.



Stage 1 Performance Software is optimized for use with a minimum of 91 OCT/95 RON fuel, producing 392 horsepower (HP) and 351 lb-ft of torque (TQ). For those with access to 93 OCT/98 RON, Unitronic’s Stage 1+ Performance Software can be used, increasing performance by an additional 25 HP and 14 TQ (417 HP/365 TQ) through optimization in the software calibration for the higher grade fuel. Both Stage 1 and Stage 1+ Performance Software are designed for a completely stock vehicle, requiring no supporting modifications.





For Clients interested in upgrading their 3.0 TFSI to the next level, Unitronic’s Supercharger Pulley Upgrade effectively raises boost levels by increasing the speed in which the supercharger spins at, allowing for additional airflow to be ingested by the engine. Without a corresponding Software calibration to make use of the increased boost levels, the system will simply bleed off excessive boost resulting in no benefits. Unitronic has developed corresponding Stage 2+ Performance Software for use with its Supercharger Pulley Upgrade to provide increases to 451 HP / 388 TQ.






Unitronic Pulley Upgrade Includes Unitronic Stage 2+ Performance Software

Applications:
B8 Audi S4
B8 Audi S5
B8.5 Audi S4
B8.5 Audi S5
C7 Audi A6
C7 Audi A7
8R Audi Q5
8R Audi SQ5

For more information, be sure to contact your local Authorized Unitronic Dealer to get yours now!

*Generally, Unitronic Performance Software clients see a 5-8% increase in fuel efficiency, under the same driving conditions. Unitronic makes no guarantees on fuel efficiency improvements, as these figures are highly variable and dependent upon driving style and conditions.

Great!

Do you support the cts pulley ?
If I buy your pulley, how much $ is added for the install of the pulley at your head office of Laval ? I'm looking at doing it around April-May.

More tuning competition should lead to better products and cheaper prices. These upgrades for an E55 are sub $500 now lol

[Deckdout2]

Trying to understand the pricing structure. Why would someone buy just a Stage 2+ without the pulley upgrade if there is no added power increase? Would it not make more sense to make the Stage 2+, the pulley upgrade and the software upgrade as 1 package? Sorry if I'm missing something here.

[GTItoS4]

Some folks have their own pulley already.

Yes, it it's best to purchase our Supercharger Pulley Upgrade, which includes our Stage 2+ Performance Software for $1600.

[Deckdout2]

This was what I was looking for. Makes sense, I just didn't see any specs listed on the pulley offered, so I wasn't sure if it was the same diameter as the one most already have, or if it was different in some way from what's available.

On their website it looks like it is. $1600 for pulley and includes stage 2+ tune

Ya, I got that part. I was just curious as to why there was just a Stage 2+ option only if it netted the same power as the Stage 2+ & Pulley.

[Maitre Absolut]

soo tempting but i'm not even used to the S4's power yet. i guess ill wait till im bored lol

Swing by our Headquarters in Laval and I'll take your for a spin in our S4.

John, love the tune and looking forward to the Uniconnect, hope it makes it on the seen before my next service. Luckily for me Steve at Zinkwerks (local Unitronic rep) is a nice guy and will help get it back to stock for the next service., but it would be nice to do it myself.

[Usa]

Is the pulley diameter for Unitronic the same as APR? Can the APR pulley be used with the uni tune?

[joewhy2k]

Ohhh okay I understand what you're saying.

[the4siswickid]

Uniconnect.....me wants. When???????

Stupid question, how noticeable is the pulley versus OEM?

Ok I'll be that guy and start off the questioning... Crank vs wheel HP numbers? Stock dyno graphs? verification of gains over stock? You've just used the Audi advertised stock HP numbers which have been shown to be inaccurate for either wheel or crank HP. If these are crank did you actually remove the engine and hook it up to a crank dyno or did you use some formula to calculate the difference? If so what was it? pulley specs? Uniconnect specs and est timeline?

While I am a huge fan of more options in the tuner market this is an incredibly incomplete release to a community that you have been a part of for many years and should be aware that these type of questions are coming.

[moose_head]

The graph says measured at the crank, and they are crediting stock at 350hp/339tq (and calculating gains from that) instead of the factory advertised 333/325.

[Laxinthe303]

Can you not go Stage 2+ or Stage 2 on 91 gas? We don't have 93 here in Colorado.

[rnkjr]

Steve, what is the rev limit and is the speed limiter removed on Stage 1+?

[OnEaNgRyBuNnY]

TCU flash? ETA? I notice all your charts end before 6,800 revs.

[Steve@Unitronic]

Steve, what is the rev limit and is the speed limiter removed on Stage 1+?

On a 6MT the rpm limiter is increased to 7200 and the speed governor is increased to 300km-h (186MPH).

Just wanted to drop in and say that I've had this tune for a little over two weeks now (I think) and couldn't be happier! I went the stage 2 route with pulley upgrade and drove away feeling like I just bought a new car. Plus these guys offer incredible customer service to back up their already amazing products!

[TexasDfwS4]

Just got off the road after a quick run with a SRT8 and this tune is amazing.....

[d.p]

Why do your dyno maps say stock 350 HP and 339 TQ? Surely that is exaggerated?

[tgsweat]

They gave crank numbers

holy post fail

Did you even bother looking at Uni's post? Theres three graphs that show the comparaison to stock @350 HP.

[anerbe]

Just got confused a bit regarding the charts above vs. the advertised gains on the website:

Stage 1 = +57HP/+25TQ
Stage 1+ = +82HP/+35TQ

The charts and data in this thread aren't quite hitting the website claimed performance gains. Either way, nice increases.

[John@Unitronic]

We appreciate your feedback and I'd be happy to clarify.

333 HP / 325 TQ is the advertised stock output figures by Audi rated at the crankshaft for the S4/S5 3.0 TFSI. Our dyno graph shows 350 HP / 339 TQ (with SAE J1349 correction) for a fully stock "333 HP" 3.0 TFSI which is are actual figures as measured by Unitronic on a MAHA LPS3000 Dynamometer, which rates output at the crankshaft. In our experience, VW and Audi are *usually* conservative in their rated crankshaft figures. Just look at the new 2.0 TSI Gen3 in the MQB platform. They are rated by VW at 210 HP / 258 TQ to the crankshaft, but we saw 234 HP / 262 TQ (with SAE J1349 correction) on the same MAHA LPS3000.

Stage 1 = +57HP/+25TQ
Stage 1+ = +82HP/+35TQ

We apply the "gain" to the advertised Audi stock figure. Also, similar to the OEM, we also underrate our advertised power figures (crankshaft) to ensure we account for the differences in environmental conditions, etc. throughout the world.

Looking at the dyno graph, i think the b8.5 DSG will need a TCU flash to benefit from the max gains which are beyond our current redline.

anyways summer wheels are my priority right now...

HERE is a quick example of a Client in Puerto Rico with a B8.5 S4 DSG who achieved 375 HP with the dyno run only running to 6000 RPM only. Had he rev'd to 6400 RPM, the peak horsepower should have been slightly higher, too.

The most accurate measurement is to physically dyno a stock car to get a baseline, and then dyno each stage as you flash and with the pulley at the end. These numbers are being baselined off of the advertised numbers?? This is basically bench racing, and who cares about crank hp really? Sorry, every car performs differently, and this delta is not as accurate in my eyes without some real world figures. I'll revisit when that happens.

Either your reading comprehension is terrible or you're intentionally being obtuse. They dyno'd a stock S4 for the baseline.

Some people are reading the numbers from the beginning of this thread (numbers come from dyno'd stock) and some people are reading the numbers on their linked web site (stock numbers are as advertised by Audi.)

[Sean@ACGAutomotive]

Happy Friday guys this is getting exciting!! Lets get some local SoCal people in for an awesome experience. Just to re-iterate, for the month of February we will be offering FREE Pre and Post dyno runs (a $150 value) on our Mustang AWD dyno here at the shop with the purchase and installation of this package.

Thank you
Sean

Poor guy spent all his money on APR mods...probably still believes in RSC tech LOL

[Thumper3]

Can you not go Stage 2+ or Stage 2 on 91 gas? We don't have 93 here in Colorado.

Just go 70/30 blend 91/E85.

But I am sure 91 works fine, they are just showing that if you put 93 in the ECU compensates and raises power more.

Enable broken record.....

Crank. Wheel. It doesn't much matter really. Even if every tuner showed numbers at the wheel you still can't compare with any high degree of accuracy if they are done on different dynos. Look at the stock curves for APR vs Unitronic, they look very different. I would hazard to say that in stock form all cars should perform very close to the same. So if that is a given then why the difference in curves? Because there are so many other variables at play.

Probably the best way to look at any dyno numbers is to compare the difference between stock and tuned, assuming both runs are done with the same car on same dyno with the same dyno configuration and same (or very similar) environmental conditions. It should be a lot more accurate to compare the gains from different dyno runs even from different dynos as long as you accept that there is still going to be some variance.

We did physically dyno (using a MAHA LPS3000 Dynamometer) a stock car to get a baseline, and then dyno'd each stage as we flashed it including our Stage 2+ Performance Software with our Supercharger Pulley Upgrade. That is precisely what is shown in the dyno graphs above.

Our Stage 2+ Performance Software is optimized for 93 octane, but can be used with 91 octane for folks that don't have access to 93. Stage 2+ results on 91 octane will be a bit reduced than the above figures considering the lesser fuel grade.
