Calling MEMBER AXEL. new JHM supercharger?

B6/7 S4/RS4
#15

Well, saki and I captured some logs yesterday and they were sent to JHM this morning. Hoping JHM can use them to put together a new tune for me.
Saki says he didn’t really feel the bogging but I still do lol. Then again, I drive it every day, he only drove it for 10 minutes.
Just this morning, the light turned amber and I was close to crossing the intersection so I punched it just a bit in third and wham, felt the car hesitate and pause for a second before getting some power.

We’ll see what JHM has to say.

true, I also drove it like a bitch for the most part as it’s on break-in, and it’s not my car.

I tell you one thing, it was funny driving a JHM tuned car after driving a stock RS4 for a month. I forgot how much better the throttle feel is. I also have to say, even on a very conservative supercharger tune, with an extra passenger, being 100lbs heavier avant, and with 100 lbs of cargo in it, the car would KILL my RS4. It was pretty funny. Logged around 550-600 RPM second like it was nothing. Take that 250 lbs out of the car, and give it the full tune and it will be ridiculous how bad my Rs4 would get stomped.

I don’t know if I’m an anomaly b/c I’m a 05.5, but I had a ebay cable that worked just fine (version 6 or so iirc). I eventually upgraded to a legit vagcom cable b/c I thought I needed it for some issues with the headlights, but didn’t so I just gave my old one away when I sold my RNS-E.

And just general info for guys out there that may have issues:
The one thing with the knock-off cables is you have to make sure you ONLY are running the software version that the cable was designed for and provided with. I.E. you can’t run a knockoff cable that came with software 5.04 to run 5.07 or 5.02 (I don’t know what all versions they have, but you get what I’m saying). So don’t “update” when it tells you the software is out of date.

So I just spoke to JHM’s tuner for the last 90 minutes and it’s all good. He went through the logs and said it’s nothing to worry about (he gave me a full technical run-down which would be too long to write here and I would probably just butcher it anyway). He’s going to send me a new tune to push the fuel pump marginally harder (something like 12%) to clear the CEL. The number of failsafes in this tune is astonishing.

Can’t wait to finish breaking the clutch in. The car’s restless and just wants to go :slight_smile:

Oh and saki, we need to schedule a weekend to make some videos (for ourselves and for JHM). I was thinking the 18th.
What do you think?

#19

That sounds about right. It’s funny everyone was freaking out about the code, saying to park the car, but I knew if it was a legit code and a problem, JHM would have told you that on Monday.

As for vids, sure. What’s the 18th?

#20

A Saturday.

#21

my calender says it’s a friday. So you mean the 19th?

#22

Doh! Yup, the 19th :slight_smile:

Finally got around to taking a few pics of the engine bay. Not much to see but here it is anyway (apologies for the dirty look, no time to clean it right now).

Update:

I received the new tune from JHM and already the car feels like it’s pulling even more than it was before which is fantastic. I don’t seem to be getting those misfires either.
That said, I got another CEL so I’ll be taking it to the mechanic tomorrow to check it out and to do some more logging. In the mean time, I’m having a blast with it now that I’m done breaking in the new clutch. Woohoo!

#25

You still don’t have a cable? Thought you ordered one?

#26

No, you’re giving me your old one :slight_smile:

#27

Beautiful car Axel!!!

Looking forward to hearing it and seeing it in the flesh!

5 minutes of boring video looking at my tail-pipe. For the sound only.

Edit: I added time stamps in the description to skip the boring stuff. Makes it a lot easier to browse (i.e., just click on the timestamps in the description)

The editing was a bit to be desired, but te soundtrack that you used was fantastic.

Do get much supercharger whine, or because it’s a centrifugal charger there is none

Almost no whine at idle and none when moving.

#31

I didn’t care about the boring stuff, it was nice hearing your V8 burbling about. There is only so much you can do with the video camera when capturing exhaust sound clips.

No whine would be very stealthy. It would be nice to have though, if only you could trigger it with a button, but I guess you have the cut gears in the accessories for that ;D

#32

It’s an Avant, stealth is part of the package :slight_smile: Just wait till I mount my cargo box lol.

#33

That was worth the watch. There are several times when you get on it and it sounds so great. One more good thing. Did you see how clean your pipes were duing the run. that is impressive I expected to see a little black smoke coming out on hard acceleration good tune work on JHMs part to keep the AF well under control.

Sounds incredible!
