Official RS5 supercharger thread!

Can email it to me and I’ll forward to Steve. redmistracingllc@icloud.com

Alternatively, can PM Steve and get his email. Either way!

That’s great @hahnmgh63 if you can email it over to @Ape_Factory (Thank you buddy) or myself that would be very helpful :+1:

As for tolerances in my transmission i was thinking it could be this and there just looser in my trans for some reason and that’s the cause.

Again tho could this be resolved with adjusting my TCU to suit my transmission by upping for example my clamping pressure or clutch pressure ? It would only need a slight tweak as the judder is very slight now after replacing everything !

I know its not the normal procedure but there must be a way around this as like i said before in dynamic mode it does not do it so what is set different in dynamic to comfort mode in the TCU ? All i could think of was the clutch/ clamping pressure being the main difference but there’s properly a lot more than just that.

Another thing i thought of was to up the revs very slightly when the clutch is engaging 1st gear ? But then that might cause driverability issues maybe :man_shrugging::man_facepalming:

Sent it to you an hour ago Steve! If you don’t see it, lemme know and I’ll resend.

One thing I just thought of…how many times have you run adaptation on the new clutches? Generally you do it once after the installation then again in 500 or so miles.
-m

I’m curious, seems a few mentioned chatter and LWCP pulley issues. Guess I’m next lol

Thank you for that email :blush::+1:
If i got this update would it effect the TCU Stage 2 tune ?

I’ve done the adaption twice so far but i have not completed the 2nd adaption as of yet as i have not put many miles on it since doing it, weather is rubbish here at the moment snow and ice not -30 @BuyTheWarranty so feel a bit stupid saying it :joy:

Thing is I had this judder before fitting all the new parts that’s the main reason for changing everything in the first place it’s defo better than it was.
Also i dont understand why it does not do it in sport mode or Dynamic mode and only in comfort mode, i wonder what the difference is between these modes ?

What have you heard about the issues people are having after fitting these LWFW ?

I’m also running the LWCP kit as well so a double whammy !! My car didn’t get on well with this kit either and JHM needed to mess with my tune to correct this ?
That’s why I’m thinking they might have to do the same with regards to this judder issue as I’ve done everything mechanical i can think of !

Ok…a few more thoughts after a bit of consulting.

FIRST AND FOREMOST!!! Run the adaptation mode fully and properly. This means the fluid has to be at operating temperature before you start! Tough with the COVID restrictions but an absolute necessity.

Why you don’t feel it in S or M…it’s more aggressive in that mode so you don’t have as much time to actually feel/hear it. It’s probably still there just in a lesser amount as you’re punching through that area of the rev range more quickly. The throttle in S and M is more aggressive than D mode.

The other thought is you could have a maintenance issue in the form of a clogged filter or screen. There are enough guys who have the same hardware and don’t have any issues. It was there before the LWFW. And the tune has nothing to do with it. This is a mechanical interface issue of some sort, plain and simple. Changing it would cause more issues or make your current issue worse.

So it’ll take some fiddling unfortunately but start with the basics, running your clutch plate adaptation 100% according to the book and completely.

Are you using OEM replacement clutch discs and liners? Any chance of an improper clutch plate install?

Ok firstly thank you for this and helping me to get this problem solved as I’m truly stuck and at a dead end.

When i run the adaption mode the first adaption you do is : Erase counter for start stop process this i have never been able to finish or complete no matter what temp i have it at 40c to 60c and i even tried it higher ? The rest always adapt ok and finish correctly.
I’ve started the adaption already and i am on the last part of adapting clutches 1 & 2 ( the driving part ) does it matter if i do this over a few days or is it best to do the whole thing until complete ?

What your saying about S mode and M mode makes sense as yesterday i did actually could feel it in both of them modes not as bad but it was there.

The filters have been replaced when i fitted the new clutches also the Mech repair kit come with new screens so these were replaced at the same time, that’s for definite as i actually did these myself.

The judder i have only started after fitting the LWFW before this it was fine ! I also understand what your saying about the tune and to fiddle with this could cause more issues.

I’m using Borg Warner friction plates and Exedy steel’s all were checked to make sure there was no defects and they were straight before putting in. I dont think the clutch plate install is an issue the guy who done it for me is very particular with his work and has done the DL501 many many times as all he does is transmissions.

I also had this judder before they were fitted its only got better and better since doing the clutch plates and fitting the Mech repair kit !

I’ll crack on with the Full Clutch Adaption and let you know how i get on.
I hope I’m giving you enough info as I’m trying to inform you the best i can, if you have any other questions then please ask away !

Thank you once again for all your doing to help me with this your a Top Geeza :sunglasses::+1::blush:

Steve, your happiness is my happiness. I just want to see your car sorted but probably not as much as you do!

Ok so OE plates and Exedy steel which is also an OE replacement. Should be fine there and like you said, the judder was there prior to the clutches being replaced.

I would do the adaptation all at once, one time, with the car fully warm (tough in the middle of winter!) until it’s complete.

Beyond that, I’m racking my brain as to what would cause it. I might look at calibrating the throttle bodies too. Just in case. It’s a quick process, easy to do.

Your to good to me buddy thank you there are very few people in this world that go that extra mile for others like you do :blush:

Ok ill do the adaption on the throttle bodies and the clutches and all in one go and keep you posted.
Does it matter i can’t get the Erase counter for start stop process to run ?

Honestly I do not know on that one…

Ok buddy, well I’ve tried to get it to run but with no joy at all and ive tried all different temps ?
Ill try again if not ill carry on as the others complete ok.
I did read somewhere that this is an issue for others who have tried and to not worry and just skip it if it does not work ? :man_shrugging:

Anyone else on here try to do a full adaption since flashing to the JHM software? I’m wondering if their TCU software somehow interferes with the “Erase Counter” process? I’ve only flashed with 034 software and it’s easy to flash back to stock (on my S5 3.0t). Haven’t bought the JHM for the RS5 yet. Can you flash it to stock and then try to do the adaption or can someone else with JHM TCU software try to do the adaption and see if it works for them?

Could be, things are modified in the tune that change logging parameters so entirely possible there are other processes affected. I haven’t had a need to run adaptation myself and I’ll be on winter weather lockdown here through Tuesday. Might be able to try it the following weekend if no one else can get to it sooner.

I had jhm retune my car when I went catless but then I had miss fire codes and he messed around with some settings and when I launched the car it felt like someone slammed the car in and out of park, so I wonder if this was the clamping pressure? I emailed him back told him what was going on resent him the logs and so far so good

I had misfire codes when i changed to catless and fitted the LWFW with the LWCP’S and JHM had to reflash the car several times and after a few logs got it sorted in the end.

Its interesting what your saying about your LC issue tho as i can not use this function being a right leg amputee and not able to use both pedal to perform LC :persevere:
I will defo have a word with JHM and ask if i can send some logs to them so they can have another look over them to see if there are any issues they can see with my tune on both the ECU/ TCU tune.
Thanks for letting me know about the problems you had with your car its good to get any info regarding all issues people have had :+1:

Hopefully an easy question, are you logging using Vagcom? And if so, what Channels are you loggging for JHM. My tune will probably be similar to Steve’s due to the Catless exhaust and LWFW, no LWCP though. Thanks,

There is a catless Stage 2 file in the JHM Power Connect right now.

I can’t get clarification from JHM if that file also includes the pulley and flywheel update that Steve is running.

I will be flashing this week, but based on others feedback, 90% chance we will need that update.

Andrew,

The file you need is on the server.

Have you signed on to the new flash server and had it scan your car? If not, do that as soon as you can, launch the ECU tuner (it’ll scan it first automatically). After it’s done with it’s scan, back out of the ECU side and then do the TCU side, same way. That way they can check to make sure yours is fully compatible with the update. “The man” can’t check anything until he has that information. Meant to send you an email yesterday but was super busy trying to clean everything up after last week’s mess.

Awesome, thank you! I get my car on Thursday.

Is it possible my TCU needs an update? I’m still running the original version from 2 years ago:

Stage 2 V KS 5.6 on the S0006 box code
