Audi B6 / B7 S4 ECU Tuning Software - V8 - by Unitronic

[boravr6]

Isn't there one on the list? V8S4Fun?

Notice that its supercharged and only .10 sec faster then a N/A JHM car?

[EUROSWAGR]

Isn't there one on the list? V8S4Fun?

Ya I knew some smart guy would see that, hence me stating NA, kind of pointless to compare a NA UNI tune to a car that is supercharged with a UNI tune.

I'm pretty sure with headers, LWFW +clutch, and lightweight wheels I can get into the 12.60s.

The one and only purpose of JHM's existence is to generate revenue. They didn't jump on an "untouched" market out of compassion for us or passion for the platform. They did it for money. Sure, the technicians might be passionate about the B6/B7 platform and/or their work but that's really just lucky for JHM. They have a group of really good guys and it shows in their after market products. JHM's success in our platform's tiny market is partially just out of luck, timing, what ever you want to call it.

Honestly I don't think luck had anything to do with it. Yes they are a business out to make money, but I think at this point they are still trying to make back all that they have put into R&D.

Lately they have also been trying to create parts for the N/A 3.0 V6 market. They haven't listed any of these parts for sale and have only sold a handful of tunes to beta testers. They have developed a number of parts for the N/A V6's and spent a good about of money on R&D and have still yet to really make any money off of it. What other companies are doing this? Making parts, spending a ton of time testing them before even attempting to make a dollar?

Basically I am not trying to deny JHM is in it to make a profit, but they are just trying to get paid for all the work that they have put into the platform. And I do think they are doing it for the compassion that we and they have for the V8 market.

The way I see it they are in it to make money. More power to them and in this mass consumer instant gratification self serving consumable goods society that we live in and participate in, buy it and enjoy it and if last more than 30 days , celebrate that the product was not sold at walmart and made in china .
And since Sears, Target, K-mart and a whole load of other retailers exist for everything else we might want, I don't see where companies like Unitronic, APR, PES, and I'm sure half a dozen companies out that are there willing to participate in this market for your dollars should be harshly flamed.

What if JHM ceased to exist tomorrow, what would you do out there ?

[B6JoeS4]

If JHM ceased to exist I would sell the S4. It's worthless to me without some solid mods

They have very little margin on many of their products, two of them being the biggest like the headers, and the clutch kit. Oh and the crank pulley is still a loss because of how much R&D went into it. Their supercharger will blow every other option out of the water and it will be 5k cheaper than the closest thing. The tune is substantialy better and people would pribably pay $700 for it but they keep it right in line with the competition. So nope, not in it for the money when you look at things like that. The guys over at JHM genuinely love making these cars go fast, and they love seeing us love our fast cars, that's why you never see a dyno sheet. A dyno sheet is used to sell up a tune or other performance parts.

That's pretty extreme Joe, you'd really sell it? I think the car is pretty fast stock...PSS9s/KW V3 and wheels and tires and it is pretty solid. Honestly the power gains be it Dyno/Butt/Strip are pretty modest unless SC'd. IMHO the biggest performance gains come in handling and weight reduction. This is just my thoughts and by no means am I questioning anyone else's method of modding. I just like hearing people's thoughts and theory. I've been contemplating these things for a while being Overseas with some of our inspection requirements I've decided to wait or not even touch the motor/emissions.

[vdubjetta02]

I have to agree with Joe, the only reason I finally got into the 4.2 S4 was that JHM was getting our cars close to the 400 BHP mark (near RS4)

Even without the sc, their mods can shave off an entire second in the 1/4 mile. That's pretty decent.

[Jupiteraudi]

If there are any UNI cars in Southeast FL, I would be happy to do some pulls all day or meet at the track to compare with my JHM tune to put this crap to bed!

[Lance.Hawk]

Yeah that is impressive. I just found it suprising that anyone would give up their car if a parts supplier was out of the picture. I don't question JHM's place in the market or quality.

^^ I agree. When I bought my S4 , JHM was only rolling into the business of 4.2V8. Even back then the car was a blast to drive and with any vehicle, you will always find something about the performance that could be improve; as I have done with all my cars as times goes by.
No I would not sell my car over JHM not existing since I would have still done an exhaust and dp, wheels and tires, better brakes or brake pads and rotors and all the other little things we do to our vehicle to make it ours .

[B6JoeS4]

I would never buy ANY car if it couldn't be modified. For me it's a hobby, not just having a fast car to drive. My money has to go somewhere right?

The reason I sold my 3.0 A4 and jumped into an S4 was because of JHM and the advancement of the platform. I'd be in something domestic with a big V8 if it weren't for JHM

Like new 'stang? CTS-V? Z06? SRT something?

Not that I'm looking to leave, but I too am of that same mindset and can't make up my mind.

I thought about it a few months ago.. but really, the new gt500's run high 11s stock (mid-high if you can launch correctly), this is with a 5.8L engine and a big blower. Camaro zl1 runs high 11's low 12s with a 6.2L engine and a smaller blower... or I could get a b7rs4, tune + exhaust, and be on par with the much more expensive ZL1. Put a TTS or JHM blower on it and I'd be on par with the gt500. All without losing the luxury and comfort an Audi offers. Not worth the switch IMO.

Terminator Cobra. Insurance is just too crazy for my age. Second choice would be the new 5.0 mustang, but not until they get the whole transmission issue sorted out

[meistah]

Terminators are bad@$$. I saw one in person for the first time earlier this year, he was revving his engine at the light... but I looked away like a little b*tch, sounded pretty fast. Just having "TERMINATOR" in huge lettering across the back of your car is sick, and they get pretty zippy with mods

I liked the CTS-V a lot but I lusted too heavily over the current body style and it's either the 550hp SC'd version or V6. I wish they would have an LS-3 option in the current body style... maybe even in a wagon.

But if my Avant was totalled tomorrow I'd probably be sitting in a Cummins Mega Cab.....

[mbgt72]

I almost agree with Joe. If JHM never entered the scene, I'd be extremely bored and tired with the car by now. And if their S/C kit had taken another year to come out, I would have left a long time ago. The S/C kit is the reason I stayed in the game really.

Suspension and wheels only go so far to driving and ownership enjoyment. The quality of parts JHM has made and improvements they provide heavily outweigh their cost to purchase when it comes to the enjoyment I've gotten from them.

Man, just as a completely stock car, you gotta appreciate the insane engineering that went into these cars. It's like everything in this car was designed around everything else in the car. I'm just a machinist but I've had the opportunity to be involved in the design and function of many of the things I make and just from that experience, the small insight I have when going over my car, all I can say is wow. It is a pleasure to take apart this car and appreciate the creativity and science behind it's design an then to drive it.... ahh. Having driven my car as it is now, I'd be sad to drive it stock again but if all I ever had was stock, I'd totally be happy.

Anyway, I gotta ask a question that might as well be rhetorical. How do you guys presume to know what the dollar amount of R&D was for something like a L/W pulley was?

JHM sells their L/W crank pulley for $350.00. Lets guess that the employee primarily responsible for directly developing/designing the product makes $30/hour. Roughly every 11.6 hours of overhead labor is the cost of one pulley. How many hours do you think actually went into designing a disc with a groove on the outside diameter and a slot cut out of it? 100 concentrated hours? Probably nothing close but even still the first dozen pulleys they sell generates profit. And headers? Talk to anyone who really knows about designing the perfect headers for a particular application and you'll be blown away at the science behind it (if you've never ventured to understand it) but it's still science. There's not guess work. For the most part you can calculate precise dimensions (there are only two: length and diameter) and be damn close to a nominal set up. A bit of tweaking until you find that nominal geometry and then bam, make a jig. Done. Hire someone who can weld (many kids learn that in high school).

I'm beginning to bash JHM and I don't want to do that. They are absolutely great. They produce genuinely quality aftermarket products and reasonable prices. Their tune is the shit and I day dream about their headers. When I do timing on my car I will likely go to them for that and other goodies while the motor is out. JHM is great. I just for some reason feel the need to dispell the idea that they are some how heroic for selling us products.

Not to mention you can go around a corner in an Audi.

I'm kind of glad your a machinist and not the engineer that designed the LWCP, it's much more than a metal disc with a slot cut out of it. The headers are also a lot more expensive to make than you would think. Read through this thread if you have a chance....

What I was saying was starting to come off as slander and I didn't mean it like that. I was exaggerating a bit but I just meant to emphasize my point is all.

I understand, but they do put a ton more R&D in than any other companies.

wow, that's moving. . . I remember when just sniffing near the 8min mark was extremely impressive.

[meistah]

Yea that mrc suspension is wicked, handles well and is pretty comfy to ride in.

However when GM runs their cars they rent out the whole ring, so the laptime is pretty optimal.

[BCsniper]

Yeah, I hate to say it, but the Camaro's have really been killing it lately. They have been leading in pretty much every LeMans race lately by a pretty substatial margin.

Don't trust the nurburgring bull crap. Car companies have modified their cars extensively and use racing drivers to reach those times. Your average American muscle car were still using leaf springs up to 2010 for suspensions.

[road race s4]

I have one question.
How many B6/7 S4's and B7 RS4's does unitronic own/operate as a "shop" vehicle?

He answered your question on the first page. They haven't even seen one in weeks much less own/operate one.

Since we haven't had the opportunity to flash an S4 at our Headquarters in the past few weeks

I have a rough idea of how many people changed from Giac/revo/uni/etc to JHM but I would like to know how many went from JHM to giac/revo/uni/etc.

That's pretty extreme Joe, you'd really sell it? I think the car is pretty fast stock...PSS9s/KW V3 and wheels and tires and it is pretty solid. Honestly the power gains be it Dyno/Butt/Strip are pretty modest unless SC'd. IMHO the biggest performance gains come in handling and weight reduction.

You don't understand because you haven't driven a JHM tuned car.

Mustang Cobras had independant rear suspension since '99. Don't get mad because S4s aren't the quickest car in the world, American Muscle cars have stepped up their game dramatically in the last 4-5 years. The interiors will always suck though!

Yup.

But you know what. Ford made a choice. Make a 550HP car and sell it to people who are more interested in whats under the hood and sell it at the 50k point, or make a fast car with luxory interior and sell it at 80k.

If it wasnt for the straight rear axle i would be all over a GT500.

Good news is 2014,2015 Ford is getting rid of the solid rear axle in the mustang. Ill be first in line for a test drive / purchase!!!!

I like the argument that leaf springs somehow equate to ridiculously inferior. What rear suspension is in a C6 Corvette? Yep, a transverse leaf spring.

Also, I chuckle at people who think 65/35 weight distribution is a better handling car than the "inferior American Muscle cars"... just because it is AWD.


Don't get me wrong, I love my Avant but let's be real here.. an autocross tyrant they are not, lol.

[Black Leaf]

WOW! I hadn't heard that. That is pretty freaking huge for them to finally make that move, after years upon years of insisting that the solid rear axle was the one true path. I wonder what finally changed their mind.

Right now if you want to avoid the sold rear axle, you could get a roush mustang.

Just wondering which car you're referring to when you're saying 65/35 weight distribution? Certainly not the Avant I hope.

I think they are trying to go for a part of the euro RWD market. Solid rear axel doesnt cut it over there.

I was mainly referring to the GT500 which I believe has a live axle and the same suspension from the entry level mustang. Does it even have upgraded brakes? The point is, the only reason that car is fast is because it puts out like 450HP. It lapped the Top Gear (BBC) test track in roughly the same time as the '04 S4. 1:30.1. Also, the Nurburgring is a very fast track with long bends and huge straits. The lap times are relative but I bet if you took all the same cars and lapped them around Suzuka circuit, the rankings would be much much different.

This will explain my point perfectly!
