ah yes, good point on the DSG limit
His slips say Palm Beach which has a DA of about 1500… 93 octane, tune, intake and piggy pipes, that is quick for a car that does not have a pulley upgrade (I don’t see it listed).
For Comparison buddy John did a best of 12.41 @ 113 mph with APR Stage 2+ carbonio, and AWE cat back on 91 with a DA of 2950 on his first time at the track. DSG helps a lot.
I agree it’s quick for a new DSG car with no DSG tune… He didn’t gut his cats he means CW piggyback… Also, another 1500 foot of DA on these cars is a decent amount… Obviously, he ran the time I have no doubt of that just seems fast for straight 93 in that DA with no DSG tweaks… Just my .02
to be realistic, 12.48 isn’t that quick. That’s 2 tenths faster than the fastest ever stock B8. So in perspective it’s not really worth talking about
You guys should be WAY more surprised and skeptical of Fonzie’s result from like 4 years ago.
Ah I thought the piggy meant his pipes, yes that is quick with no DSG tune or pulley.
What is the record for a factory B8 DSG?
Serious question - is there a way to measure coefficient of friction on the pavement of these tracks? Probably makes a huge difference, more than DA. That has to account for the variance. I’m going to assume they’re all level within 4" of height.
Separately, I have a suspension question about drag racing. The new Mustang has a drag mode where the magneto-electric rear dampers go soft on launch, and then stiffen up when the car starts moving. But when I look at drag racing suspension kits for the normal V8 Mustangs they have like 150 pound front spring and an 800 pound rear spring. So I guess that penalizes launch but helps the front end stay planted if you’re making crazy supercharged power?
In case Mike isn’t still here - he added a pulley with the Chipwerke for these runs (which he has described in the Chipwerke thread and has logs posted as well).
Running a pulley with that map sensor spoof is extremely ballsy. I would absolutely not even think of doing that. Did they build him a different CW spoof map or he can just turn up the knobs? Which means he is now way further off the loads then the ECU thinks.
I absolutely don’t think that knock detection taken at a 5Hz sample rate from a diagnostic interface is indicative of engine safety for a piston that is firing every 20 msec at 6k RPM
6000 RPM * (1 min / 60 sec) * (1 fire / 2 revolutions) = 50 fires/ sec => .02 sec / fire
Yeah it is ballsy! I was fairly impressed with the logs. The lambda was right on (despite a higher differential in fake load/airflow vs actual). He did see a little knock correction on CW (maybe for the first time?). One thing is the stock B8.5 load/timing curves are apparently quite conservative (stay well below the knock threshold) compared to B8 so I think this gives him room for error. Other cars I could foresee more severe knock correction. Can’t comment on what we miss due to the low sample rate but it seems a valid point.
If anything, you want more friction with the drag surface to hook your tires up. And no, that does not make a bigger difference than DA lol Maybe it matters for the fuel economy on a toyota corolla.
Are you talking about an older mustang, or a S550? Cause the older mustangs had obviously different suspension setups. Here is a new one going fast…

There was supposedly an old hack with the old Pontiac Sunbird 2L turbo: if you shut off and restarted the car while the MAP was under vacuum, you could trick the car into recalibrating extra boost.
I remember throwing resistors on my B18C motors IAT to get richer or leaner too…
This CW thing is pretty much as hack-ish as that…lol!
Naw bro, it has something they call rev sens http://www.audizine.com/forum/showthread.php/645409-B8-5-S4-stock-versus-APR-Stage-1-tune-versus-Chipwerke-piggy-back?p=11144085&viewfull=1#post11144085
This pic looks like something from south park haha

AZT, thanks! Didn’t know he was running a pulley… Sorry gave up on the chipwerkes threads months ago… He should disclose that in his 1/4 post…
Drob, LOL @ The South Park analogy…
Say what you want about the CW - it is a crude device - what impresses me is how the B8 S4 adapts it with such elegance. Suddently telling a forced induction motor it is flowing 20% less air @ wide open throttle would get you in alot of trouble with other motors lol.
I’d say the car running full time closed loop really helps here.
has anyone made the spinal tap joke yet out the knobs being turned up to 11?
I don’t understand why he doesn’t just go stage2 with GAIC or APR? What is he gaining from taking on this additional risk versus just going a proven low-risk route if he really does want to go faster? I guess its just for fun and if the engine blows, no worries, just get another?
Or he’s getting a cut of every device sold so the better it shows the better his pocket book is? That would be my guess…
It does seem VERY strange. Although he did vehemently deny any involvement in the business when he came here and then ran away. The first time lol.
It’s funny but basically the only guys to get the chipwerke are corner cutters trying to save a buck over the real deal and hoping to get away with it.
Turns out Mike is the same with his maintenance…took his car to a quick oil change shop and it looks like whole trying to save 20 bucks it will cost him about a thousand.
Good to see him learn a lesson. Maybe he will abandon chipwerke and the inevitable xspower downpipes /exhaust after this.
[QUOTE=bhvrdr]I already blame myself enough and am aware what I did was stupid by not taking my car to a more trusted shop or doing the work myself but i’ll share this post anyways and be ready for the flaming 
I was looking through Groupon and saw a $49 deal to get a full synthetic oil change at the Valvoline Instant Oil Change place. So I figured, why not do an added 5K interval change at such a cheap price. I cant buy the parts that cheap so whats to lose right? …and there is where my mistake lies and what turned into a 4 hour ordeal that involved police.
I pulled up to the oil change place and stayed in the car. A couple minutes into the change I feel a jarring / ripping sensation through the floor of the car. I’m thinking, “Hmmm, I hope they know to slide the aero belly pan to the rear to let it drop down instead of pulling on it.” …I make a mental note.
So now they are at the stage where the person up top starts to pour in the motor oil. He starts to poor it in and stops pretty quickly yelling to the guy below to make sure he drained it all out as it is overflowing. … Mental note number two. Hmm.
So a few minutes go buy and I call the manager over and mention to him that I would appreciate it if he make sure all the 1/4 turn fasteners are put correctly back into place because they are very expensive to replace. He smiles and assures me he will make sure that happens.
So now the oil is supposedly back in the car and we are about to close our transaction. I’m standing at the front of the car now and i’m staring at a 1/4 turn fastener sitting on the ground under the front of my car. I’m waiting…waiting…waiting for someone to pick it up to put it in or to tell me “You’re all set.” …and sure enough I hear…“You’re all set you are good to go.” So I bend over and pick up the 1/4 turn fastener and ask to talk to the manager.
The manager comes over and I point out to him that his person just left $20 worth of fastener of mine on the floor and I’d like to go into his pit to see what else is missing. He takes me down into the pit where I see this…

I’m looking up at the car at first and I see the DSG drain plug right there and there is DSG fluid all over it and dripping. I’m thinking “Why can I see the DSG drain plug? Theres supposed to be an aero pan covering this?” and i’m also thinking…“Oh crap, they drained the DSG fluid.”
As I keep looking up my brain starts to register what it is seeing. Holy crap, this guy cut my car into pieces. My aero pan has a huge hole cut into it. I’m standing in the oil pit now with the tech and the manager and I ask the tech if he did this to my car and if he drained my DSG fluid. He says absolutely not. Well since I am under my car every week and I know no one else was under my car I’m finding that very hard to believe. So I took it upon myself to walk around their oil pit until I found two of these…

Yeah, sitting in their trash can are two pieces of my aero pan he cut out. At this point i’m thinking that I need witnesses, and alot of them. I call my wife and I called the police so I could at least get a report.
It looks like this is what happens…
- Employee cuts hole in transmission aero pan and drains DSG fluid.
- Tech tries to put in motor oil and it overflows all over the engine because no engine oil was ever removed.
- Tech and manager were going to let me drive on my way with no DSG fluid and massively overfilled engine oil in which case id likely be out an engine and transmission.
I had the car flat bedded to Audi and will await the damage on MON. I’m worried they tried to cover up their mistake of draining the DSG fluid and put some no name brand automatic transmission fluid in the DSG in which case I dont even want to know how I can get Audi to test the fluid in there to see if it is non OEM.
I have learned my lesson. This sunday sucks.
