**JHM 3 Liter Build**

#21

Hey Guys -

I wanted to keep updating our build here because again, we feel it’s best to keep the people informed who are supporting us and the community. We appreciate people going out of their way to get the community the new information needed to help this platform.

We just acquired a 3 liter car of our own that’s en route to our shop. However just because we’ve got a car of our own right now, doesn’t mean that we don’t want to see your cars in at JHM! We want to learn EVERYTHING about these cars and we can’t do that unless we see more of them. So if you’re local to us or if you’re up for shipping your car, we’d love to have it at JHM. The more cars we can see the more maintenance issues we can identify, understand, and offer solutions for.

The car we’ve acquired is another automatic which will allow us to dive into the transmission tune even further… because I’m sure motorsports916 will eventually want his car back! As soon as we take delivery of that car, we’ll be able to keep increasing our offerings for the Three Liter community.

Now we’re not going to leave our manual transmission guys out to dry… We are making a B6-A4 3 Liter Lightweight Flywheel to address concerns we’ve heard and seen where the bearing in the stock dual-mass flywheel is separating. On the B6-S4s we’ve seen this cause anything from a minor vibration throughout the RPM range to the flywheel completely separating inside of the bell housing and cracking the transmission casing. Stay tuned for further information about this flywheel and a JHM clutch kit.

As far as the ECU tune goes, it took us a few days to hack the 3 Liter ECU but now we’re making progress. Version 1.5 of the tune is definitely making solid power at the high end of the RPM range. There’s still a lot of progress to be made though.

Thanks again for the interest and support. We’ll keep you posted.

Thanks keaton. maybe I need to get a 3.0 now as well. I love my S5 and you guys did outstanding work on the ECU tune. I would love to have a winter car maybe the 3.0 will be just that.

Also thanks for updateing this site. I trully don’t even want to follow anything on AudiZine anymore that regards the 3.0. Its clear the 1.8T guys are not able to handle the develpoment of the 3.0 and the thread that has been started just turns into the 1.8T hate a 3.0 thread.

I know this might not be the venue for this. But today was a classic case of a 1.8T guy that couldn’t stand the thought of a fello B6 member stoping his possible 1.8T build to think about swapping back in the 3.0 and getting it supercharged by JHM… Something I hope you guys do… this vinnie guy then goes on a semi mential break down about something that isn’t even happening. In the end. Its clear to me that if the 3.0 guys stand a chance to enjoy and talk about there gains and or advancements it won’t be able to happen on AudiZine.

My thoughts are you might just want to start sending 3.0 guys to this site. My .02

good stuff Keaton

#24

Officially jumped off AZ thread*

So, spoke to Keaton today. bought some extra time so they will have my car thru around mid-july if they need it.I am truly excited too see all the intreats in this platform.

And, I have to admit it BLOWS not having my car. I feel like a kid waiting to open presents on Christmas morning… But after speaking with Keagton this morning, I know its going to be well worth it!

#25

Its painfull reading ON AZ. While you don’t like to see the back&forth its good to see someone sticking it to the negitive comments. The funny thing is the 1.8T guys come in bash then act all WOOOOOH… why are you reacting so harsh.

If You ask me. Both clint and the vinny guy need to grow up. I trully believe that the more sucuessfull these 1.8T guys believe themselves to be the more there going to be super Pro 1.8T and chip away at the advancment of anything but… Thats how I see it.

Still great to have you on here and you make the first big step for these 3.0 guys motorsports916. Being a Audi tech for 33years the 3.0 motor was one on its own. Its going to be a difficult motor to get power out of In my opinion but its great to see that JHM has taken on the challenge and Im eager to see where this can go from here

#26

^WOW 33 years!?! Almost as long as they’ve been in the states :o

#27

dropping by guys reading all this good news gets me excited. i tried fellas but these guy on the zine are ignorant. no point. i’m glad this can be our haven to just talk 3.0 without the “experts” coming in. ANYWHO what is all this talk about a blower. i just passed on some ROTI’S so dont let me down JHM. lol. j/p

#28

Yeah, concave Roti’s are not easy to pass up!!! The new series look sooo damn sexy!!!

Can’t wait to see where things are going with the 3.0

Thanks JHM, Keaton, and those who first got serious about this lending cars, time, and knowledge! All of these things are the perfect ingredients for results!!!

#29

honestly the more 3.0 guys that are here the better it is for the 3.0 guys. This site is filled with lots of guys that know what there doing and are excited about seeing the Audi N/a class of cars get off the ground.

These threads will advance further and faster. The fact that JHM has some presents here is only better for the development and communication with them during the development.

Thank you guys for all of your support thus far. I was just doing a little thinking about all of the 1.8t vs 3.0 back and forth and was wondering if you guys would like to see some pulls between the two. I drive a 2004 A4 Avant, 1.8t and it’s got everything short of a BT. I have an APR tune with the big injector file, a 3 inch downpipe (no cat) and an APR cat-back exhaust. That would make it stage ii+, I believe… Anyway, the more I drive motorsports’ car, the more I feel like this will be a good race.

If you guys are into it (I’ve already cleared it with motorsports916), I think we’re going to do a few pulls of my stage ii+ 1.8t vs the 3.0 stock and then with our early revision of the tune. We’ll see what happens…

The Stand off. Testing the bentch mark Stage 2+ 1.8T Vs 3.0
#31

Yes. I would love to see that!

#32

Yes, I would love to see that also.

#33

I think I can speak for everyone here when I say “Heck yeah lets see that!” ;D

I honestly could care less about it being 1.8t vs 3.0
I know thats what came of it but I simply want to see the improvements that can be made with the 3.0 period! 8)

#34

Well said sir!

#35

i honestly dont care about the 1.8 guys. because i know that in JHM’s hands we will be faster then most of them. honestly i can count the number of people on the zine who have a “quick” a4 1.8t. my expectations are honestly for it to drive as fast or if not faster then an m3 e46. i love the way that engine feels torquey and meaty. if its anything close to that i will honestly be happy. that might be alot to ask for but i think its attainable. but once again we can speculate all we want at the end of the day we have to be as patient as possible and let these guys do what they do best.

Hey Guys -

I hope you’re all having a good Fourth. We had a super busy week with the 3 liter and it’s taken me a few days off to recover from all the tuning, logging, and tuning and logging. I did want to keep you guys updated about what we’ve done so far though.

As you can see from the video posted in the head to head thread, the JHM tune on motorsports916’s car has made some noticeable power gains over stock. In addition to that, the car that our calibrator has picked up was finally delivered and his car has seen the benefits of the tune as well.

We’ve learned a few things hardware wise too:

  • COILPACKS: In order to get the most power out of this car you’ll need to make sure that your coilpacks are updated to the latest Audi revision (done for free at your dealer). Our tune makes a lot more torque over the stock tune by using the ignition system much more effectively. Along the same lines, you’ll want to make sure you’re at least running the OEM specified spark plug, if not something better. We’re still trying to find out whether or not plugs we run on the 4.2s will be a good match for the 3.0.

  • CATALYTIC CONVERTERS: I know a lot of you have already come to this conclusion, but we’ve found that the cats on this exhaust system are a major limiting factor. Due to the fact that we’re flowing a lot more air with this new tune the stock cats heat up a lot faster and starts to hamper the car’s performance. However, we’re building our tune so it will adapt UP. Motorsports916’s car still has the cats on and it is definitely moving out faster than stock. However, we’re confident that once we upgrade his exhaust system by either gutting the cats from his stock pipes or fabricating new downpipes, his car will perform that much better from the upgrade. This will be the same for anyone with a stock exhaust system: you’ll see solid gains with our tune on stock exhaust and then once you begin to upgrade, the tune will be able to grow with you.

  • AUTOMATIC TRANSMISSIONS: Finally, those of you with automatic transmissions will want to seriously consider getting our transmission tune when you purchase the ECU tune. We were able to make solid power without a TCU tune but once we added the TCU tuning to the ECU tuning it really allowed us to use the new found power better. The TCU tune basically allows us to open up the torque converter a little bit more. This puts the power to the transmission and then to the ground sooner in the RPM band. Additionally, the things Kurt can do to the up-shifts on the Tiptronic Transmission Tuning is just awesome. The car is snappy. The shifts are noticeably faster making the car a lot more fun.

Overall, we’re not satisfied with where the tune is at right now as a final product. Even though we’ve seen solid gains, we still believe that we can do more. That being said, we feel like version 8 as we have it right now is solid enough to put in on a few cars as a “3 Liter Beta Tune”. This will enable us to get some feedback from you guys and allow us to continue making progress on the tune while implementing user suggestions as needed.

Thanks for “tuning” in. We’ll continue to keep you posted! Thanks for the support, audirevolution.net.

so, any plans for a LWFW for us 6MT guys?

#38

Thanks for the update. It’s very exciting to hear things are going well.

I believe JHM said they were looking into a lightweight flywheel for the manual guys.

How difficult is it to remove the downpipes on the 3.0? Is it feasible for the casual backyard mechanic?

#39

Its getting cut this Thursday. Big issues with the 3.0 flywheel. Its not something that we can just adapt from another platform. The 3.0 has its own flywheel and thus JHM needs to tool up just for that. Not sure cost wise but I don’t see it being more then 100$ more then a stock one if you were to replace it.

I plan on seeing how the aftermarket JHM Dp’s fit on my car so Ill do a thuro walk threw and step by step DYS video and post thread on it. After all the swear words are out the window and I find the best way to do it ill post it.

#40

THANKS FOR THE UPDATE DUDE! IT ALL SOUNDS GREAT! :slight_smile:

I might be interested in doing this Beta tune, who could I talk to so that I could get some more information about it???

Also I am almost positive there is a aluminum flywheel available for our cars because I just put a transmission and new clutch, flywheel, nuts, bolts, the whole nine yards in my 6 speed tranny. And I remember there being one available because I debated long and hard on getting one but at the time but decided to continued\ to keep it stock. I will look for it and post it if I can. Also I remember the reason I didn’t get it because it was single mass and stock is dual mass and I was told it would not be as smooth with the single mass and I didn’t like the thought of that. Or maybe i’m missing something here?
