JHM B8 S5 4.2L FSI Tuning is Officially Available!

[Jake@JHM]

Introducing JHM Tuning for the B8-S5 with the 32v 4.2l FSI V8!!!



We have specialized in tuning naturally aspirated (NA) or "all motor" 4.2L V8 engines since we started tuning the B6-S4 in 2008. Ever since then we have been the number one company when it comes to Audi V8 performance. Like our success with the B6-B7 S4 and B7 RS4 has shown, our software has been proven time and time again to deliver real world performance. That continues with our tuning for the B8-S5 4.2L FSI V8. We purchased our in-house B8-S5 4.2L in mid-2013 and immediately began developing software. After countless revisions and putting the vehicle through our rigorous R&D process, we are happy to now offer the ultimate performance software for your B8-S5 4.2L FSI V8!

In true JHM fashion, here is some footage of our in-house, record setting B8-S5 running 12.6 seconds at 108 mph in the quarter mile!



Not only does our software perform, but it performs time and time again. Here are three back-to-back 12 second passes:



JHM Performance Software for the B8-S5 4.2L FSI V8 will completely change the dynamics of how your S5 performs. This is because we change hundreds of ECU parameters to extract as much power possible and doing so without removing OEM safety parameters. You will experience much more torque throughout the entire RPM range and notice how much more powerful the car is when coming out of shifts. Not to mention our famous Launch Assist feature will help you execute a consistent launch each and every time. Our software turns your car into something that the S5 should have been from the factory.

RECOMMENDED SUPPORTING MODIFICATIONS

Our software alone will completely transform your S5. However, if you are looking to extract even more power, here are a coupe modifications we highly recommend!

- JHM 2.5" Catless Test Pipes: Our 2.5" catless test pipes are very beneficial when it comes to making more power with the B8-S5. Removing the restrictive OEM catalysts will allow your engine to flow more exhaust and make more power.

- JHM 2.5" Cat-Back Exhaust System: The 2.5" exhaust system that we offer for the B8-S5 will allow the exhaust to flow more efficiently with the calculated scavenging effect of our X-Pipe, allowing you to make more power.

I've had your tune in my S5 for more than 6 months......are there any changes between this "official" release and the one I have?

+1 was about to ask this ive had the tune for about a year, any changes??

[Jake@JHM]

Same, we just have it finalized for every North American ECU now

[thenewbruno]

In case anyone is wondering, this tune is AMAZING

Sick of your S5 feeling lazy with all the factory loaded throttle restrictions? GET THIS TUNE

Want to feel like your S5 has a turbo boost at 3500 RPM? GET THIS TUNE

I drove a 6MT V8 S5 for 15,000 miles bone stock. And I can say - JHM tune/exhaust truly improves V8 S5 driving experience by 100%.

I have a 2012 4.2l s5 with a revo stage 1 tune. It has deff made a difference over stock but is it worth switching from the revo to the JHM, will the difference be that much more noticeable.

[milesed]

Is there a before/after dyno sheet?

[chrissurfr]

would love to see some test pipes and a tune for the RS5. If you can do 12.5 in that car you guys can break 11s in the RS.

[thenewbruno]

5hp sounds great

So we're to listen to the guy with the skinnier than stock exhaust for performance parts evaluation?

Or should we watch the 1/4 mile footage that Jake graciously posted. Hmm.

JHM Tune/exhaust caused a V8 S5 to pick up 6mph in the quarter. That's 50hp talking, on the "maxed out" 4.2 platform.

[Jake@JHM]

Unfortunately guys we do not support Dynos, as they can be manipulated/fluffed and that every dyno and every car will yield different results.

We have been the number 1 company in the 4.2L tuning game for quite some time. Here is a poll taken in the B6-B7 S4 and RS4 section: http://www.audizine.com/forum/showth...ustomer-review

[JoshDub]

Says the guy with the Capristo LOL

And the 2k noise box

[SLU_S5]

I've always been baffled by the unwillingness to do dyno testing... especially since all other competitors with a respectable "off the shelf" offer dyno results.

How about a Stock vs. Stock + JHM Tuned 1/4 mile time comparison?

I've heard good things, but they're really all just opinions and "butt dyno" results.

"Hey everyone! We were successful with the previous iterations of the 4.2 V8... Buy this new tune. It's great!" will not make me a customer. Quantitative, fact-driven data will.

Their employee just told you that they don't like the dyno because too many tuners abuse it to sell junk.

Tuners should be selling acceleration, not dyno sheets, shouldn't they? Jhm Motorsports showed significant acceleration gains on a video where they took an S5 12.60 @ 108 mph in the 1/4 mile. Thats the same trap speed as the fastest stock B7 RS4 ever, and the 12.60 is even quicker (fastest rs4 went 12.75@108). You know...the 420 hp RS4. So there's your dyno.

The guy above said it. They gained 5 or 6 mph of trap speed vs stock (most stock s5 tests are in the 13.2-13.4 @ 102-103 range). That would require gaining 50 or so hp.

But you want it on paper?

Here's what AMS, world famous gtr tuners, did to show people that dynos are basically bullshit and shouldn't be trusted when used to sell parts.

^Pure speculation still. The 12 second S5 also has numerous supporting mods - many of which the typical S5 owner will never have (test pipes, lightweight rotors, crank pulley, etc).

I never said that Dyno sheets will prove how fast a car is. They could, however, help us to figure out improvements in power after a tune.

If you're not going by dyno results to prove the improvements, there better be another quantitative measure.

JHM goes by 1/4 mile stats. Ok, fair enough.

BUT...

What's the 1/4 mile time and trap speed of a completely stock S5 with ONLY the JHM tune? That's the real mystery here...

I'll bet you my car's title that it's not even close to 12.6

For reference, I was running high 13s with the mods in my signature. There's a thread somewhere on here with other member's 1/4 mile times (some with tunes) and my numbers were toward the better end of all those listed.

Your modlist is not doing much, if anything. No offense. So we can start with that. In fact it might make you slower than stock. That open intake sure is pretty and carbon fibre but there's a reason audi used a closed airbox on the s4/rs4/s5/rs5. That engine Bay is a furnace and you don't want an open element intake drawing in engine Bay heat. This is 4.2 101. We learned this in the b6 world 8 years ago. From jhm. Sure they could have made hundreds of thousands of dollars selling intakes. Instead they told you not to because they're an acceleration company.

And if you're a 'fast' s5 going high 13s, and you don't understand the value of the jhm car making that 12.60 @ 108 pass you're probably beyond helping.

[SLU_S5]

You're missing the point completely. Read my earlier response once more and please try again.

Also,

1.) Open intake? The intake I have is practically the same as stock except it has a carbon lid. It's ok, you probably wouldn't know since it sounds like you don't have one.

2.) I never called my car fast.

3.) I never said the 12.6 car isn't impressive. That's not what I'm arguing here.

[JoshDub]

I would just like to see stock vs tune only. I'd be a player once I can find more performance info. I'm not going to be getting lightweight rotors, wheels, or a lwfw.

[EUROSWAGR]

So SLU_S5 relied in dyno testing for all of the mods in his sigaturr? If so...they either lied to him or he is a hypocrite.

I personally tested my B7 S4 with a JHM tune with before/after dynos and before/after 1/4 visits. The gains on the dyno translated almost perfectly to acceleration gains. JHM has built their reputation on acceleration testing and they aren't going to suddenly change that for a platform that from my point of view has no clue what performance or acceleration means.

[EUROSWAGR]

I would just like to see stock vs tune only. I'd be a player once I can find more performance info. I'm not going to be getting lightweight rotors, wheels, or a lwfw.

If you watch the video and look at the mods a few of their 12.8 passes were basically tune and exhaust for power adders. Sure the clutch and LWFW may have helped a little on those passes, but the impact is minimal.

[Axel-]

I've always been baffled by the unwillingness to do dyno testing... especially since all other competitors with a respectable "off the shelf" offer dyno results.

I've always been baffled by the willingness of some members to blindly accept any dyno graphs provided by tuners trying to sell their wares.

Those same people think that a dyno is a controlled environment and every dyno must be the same when in actual fact, a dyno can be manipulated to say whatever the tuner wants it to say. And even if the tuner was completely honest and legit and provided an un-manipulated dyno, there are tons of different type of dynos out there, use different mechanical and computational methods to attain their numbers meaning the same car can have a huge range of numbers by going from dyno to dyno.

Dynos are used to optimize a tune (which JHM does themselves). Dynos are NOT used to display a general benchmark in an attempt to represent an entire line.

It's the difference between the concept of "relative" and "absolute". A dyno is always relative to the specific car and the specific dyno, never absolute (not meant to represent every model of that car).

The ignorance of such basic concepts of some members on a car forum baffles me.

As for this JHM tune, if thousands of people claiming it's the best tune for this specific engine isn't enough for those people on the fence, nothing will ever be enough.

[SLU_S5]

Enter the JHM fanboys!!! Nice to see that you guys have S5s also!

Yes, dyno sheets would be nice to see what the approximate delta might be (yes, a dyno can find that). However, that is NOT what I am asking for here. If you actually read my posts in their entirety you would notice that I am simply asking for one particular set of 1/4 mile results - STOCK vs STOCK + JHM Tune.

Take some time to read my argument and come back with an intelligent response.

[JoshDub]

That's a load of crap. reducing rotating mass makes a huge improvement. The LWFW, lightweight rotors, and lightweight wheels will have a tremendous impact over the stock versions.

Why is it so unreasonable to want a comparison of tune vs no tune?

[Bianco]

I'm still trying to figure out what "STOCK + JHM TUNE" means...the car is no longer stock if its tuned. Not sure how someone who contradicts themselves like that can then ask for an 'intelligent' response with a straight face. Maybe you meant to say stock vs. just JHM tuned? Do clarify please. Intelligently.

As JHM mentioned in the thread and on their webpage they don't recommend tuning your car without doing some exhaust work first. The same applies to the RS5. Same applies to the 4.2 S4 and the B7 RS4. Try to remember this is a normally aspirated platform. So why would they show the results of a mod path they think is unwise? Makes no sense. Kind of like you running high 13s 1/4 mile times yet you're complaining about the one company to actually show some performance proof for the platform doesn't make any sense.

p.s. didn't you buy a 3.0T exhaust for your 4.2? and you're the intelligent performance guy? lol

Why is it so unreasonable to want a comparison of tune vs no tune?

wasn't it just a flywheel? no rotors etc. not the 12.60 the 12.8 runs. thought that's what he said. tune/exhaust/lwfw. You can quantify the acceleration gains of a lwfw pretty easily. It's not huge, but definitely helps. If put another way, if they sold the LWFW and said it shaves a tenth and adds 1 mph to your quarter mile time, they'd probably get run off the forum for being too optimistic about shaving 10 lbs rotating.

with respect to tune vs. no tune, see my previous post. JHM doesn't recommend a car with a tune and no exhaust mods. Most people will do exhaust mods anyway, so not sure why anyone wants to see just a tune runs.

[Bianco]

I've always been baffled by the unwillingness to do dyno testing... especially since all other competitors with a respectable "off the shelf" offer dyno results.

I think it's baffling that nobody offers acceleration testing proof for acceleration parts, when we know the dyno is easily manipulated. Can you share ANY acceleration testing proof from anyone else?

Almost every other car platform wants acceleration testing. Dynos are interesting but acceleration is the standard. Subie, M, AMG, GTR, domestic...all want acceleration and the big tuners show acceleration.

[SLU_S5]

^ No need to get pedantic. Take a stock S5, and only add the JHM tune. I don't think anyone else was scratching their head over this one.

Thanks for really adding some more value to the conversation. How's your S5 by the way?

[thenewbruno]

Enter the JHM fanboys!!!

Perhaps you've forgotten where we're having this discussion. We're on a JHM S5 tuner's thread. I'm a JHM-tuned S5 owner. I'm quite sure I'M in the right place, saying the right thing, here. You?

How's your S5 by the way?

Dunno about his but mine is exquisite.

Sounds like you missed the part where jhm said not to do this

[SLU_S5]

Bruno,

I was referring to those that do not have S5s but feel the need to comment on this S5 specific thread. Your comments have been helpful.

I have been considering a tune for quite some time - trying to decide between APR and JHM. Before I make a decision, I'd ideally like to see more empirical evidence of how well the JHM tune performs since I will not be adding the entire suite of JHM products (like their 12.6 car). Apparently some folks find it a huge problem to request this information...

I have friends with APR tuned S5s who are well satisfied - plus there is plenty of evidence to support how well it performs (1/4 mile times and dyno sheets). APR also offers a 30 day money back guarantee so I am not too concerned with that route.

Sounds like you missed the part where jhm said not to do this

The very first post by Jake at JHM says "our software ALONE will completely transform your S5"... So yeah, don't do it. It basically means the same thing.

I thought that Jake@JHM was pretty clear in his post. There is a whole paragraph describing the changes to the ECU just above the bolded sentence that you quoted. Just saying.

JHM Performance Software for the B8-S5 4.2L FSI V8 will completely change the dynamics of how your S5 performs. This is because we change hundreds of ECU parameters to extract as much power possible and doing so without removing OEM safety parameters. You will experience much more torque throughout the entire RPM range and notice how much more powerful the car is when coming out of shifts. Not to mention our famous Launch Assist feature will help you execute a consistent launch each and every time. Our software turns your car into something that the S5 should have been from the factory.

A lot of the B6/7 S4 owners would get just the tune and do exhaust later on because they were sooooo happy with the tune. Just the tune alone made a huge difference.

[thenewbruno]

Well I got the exhaust first. I was first and foremost motivated to get the sound of it going. Very happy there.

Then I got the tune 4 months later - so you may as well consider me somewhat a case of stock vs. stock+tune since by the time I got the tune whatever the exhaust was doing (besides the heavenly sound) now felt normal.

I remember my shakedown drive right after tuning. I didn't need to go any further than pulling out of my driveway to feel that the car was better now. And then - turning off the main road onto my street then up the little hill. These things that I've done hundreds if not thousands of times - the same way every time, with throttle modulation within a whisper of identical every time....THIS time the car was charging up that little hill, even though I was feathering the gas down the same way I do every time. It felt different; better. The laziness was gone. It revs up smooth and linear now.

When Jake says the tune alone is a great upgrade - it's for those reasons. The car is more tractable, more driveable, more powerful, more everything you want.

Hey, I'm with you on this one. I was just being sarcastic in my earlier response. Jakes post was very clear. Not sure why this other guy (Bianco) interpreted the original post as "Do not have your car tuned if your car is otherwise stock"...




Good review, Bruno. It sounds like a huge improvement, and I really like the thought of having a much smoother power band. I'm probably due for a carbon cleaning soon, but I've noticed that my throttle response gets slightly choppy especially under hard acceleration.

I just wish there could be a way to directly compare the APR and JHM tunes (reason why I'm looking for some numbers in this thread). They do sound pretty similar after all.

[Bianco]

Slu Why not post the quarter mile times for the Apr cars that you were speaking about and then compare those?

That jhm video shows a run with just tune and full exhaust as well as the lwfw. It went 12.83 on the third pass in 20 minutes.

Has any Apr car come within 3 tenths of that?

[JoshDub]

The 12.8-12.9 passes were with stock wheels and rotors. But it was catless.

At no point does JHM not recommend this tune with a stock exhaust. This is a direct quote from the first post

Our software alone will completely transform your S5. However, if you are looking to extract even more power, here are a coupe modifications we highly recommend!

In no way does that say "Don't get this tune with a stock exhaust"

The 12.8 car has more than just the tune, exhaust, and flywheel. Look it up.

IIRC we were looking at a 13.5 - 13.6 with the APR tune on a consumers car. No lightweight components, stock clutch and stock cats. Driven by the customer and not an APR rep. I'll have to find the actual post that shares a bunch of 1/4 mile times on several other S5s - it's buried somewhere on this site.

Put the stock cats, stock clutch, stock flywheel back on the 12.8 car and I'd bet it would run mid 13s also. Could be low 13s but It's just all guesswork until someone actually tests it.
