Strange logs of DxC's car

B5 S4/ RS4
#1

He posted logs of his car…first he has gotten around to testing the turbo that he claims to have invented (and that JHM has been testing/selling for two years, go figure!).

Anyway first logs I’ve seen from a B5 S4 without fats time. EVER. Strange omission? No, deliberate.

Since his car is seeing about 270 GPS and peaking (smoothed) at a modest 0.40 g of acceleration in excellent weather for making power I am just wondering why everyone is calling the results awesome? Lots of thumbs up and ass kissing posts in his logs thread. Those maf and g stats are like a well sorted stage 2 B5 or my stock RS4 for crying out loud, also known as a high twelve second car that traps 108-9. My car should be canon fodder for a stage three B5…and anyone who has seen a log in the B5 section should see that. But the back patting is off the charts.

This might be the slowest stage three car ever. Good for a FATS time in the fours and a solid high twelve second quarter mile. Are these kids looking at the logs and only seeing the boost and assuming it is fast because it makes 22 psi

For perspective, a few longitudinal acceleration in G logs from other cars using ECUX

can’t remember whose car, but a well sorted stage 3 car
smoothed G peak at 0.55

Then of course there is DxC’s car.
Smoothed G peak at 0.40. HWUT?

Anyway, why is his car not even logged yet…to the point that this is a victory that he is attempting to boast about? If he really invented these turbos ‘years’ ago, why is it that his friends at JHM were actually logging their own car in 2010-2011…logging customer cars in early 2011…running 10.8 in late 2011…seeing customers by the dozens with the turbos in 2011-2012…and having the first customer to hit the quarter mile early last month (11.7 @ 125 on straight pump in an avant)…all before this other dude has even logged his fucking car?

Now that he has logged the car/turbos, he has posted a myriad of excuses
‘break in file’
‘stock motor so taking it easy’ (even though the RS6r car went 11.7 @ 125 stock motor on pump gas lol)
‘needs new injectors’
‘needs new intercoolers’

Is this guy for fucking real? And are people really eating shit out of his hand at the petting zoo the way it looks on Audizine?

Pretty incredible.

its more waste. This is apparently a car that this guy has had these turbos on for a long time… he has been talking about it… yet there are now all these issue… come on… these guys have been playing catch up… They clarly got cought with a old version of the JHM turbo… they are latching on to the hopes that after they sent that to china that JHM has changed nothing different. this is why DXC was asking people what changes were made to the JHM updated turbos…

There is a small group that are bying into this. Naudlee and him have been working to gether and trying to cover it up. The only other side of teh story wouod be that DXC had no turbos or idea what was going on till naudlee and him got teh first set of the china knock off turbos from chaina. Then all the acusations came out. They think a compressure cover equles end game. Its not that hard to go on JHMs web site and then contact one of teh companys overseas and get them to picee a turbo togher for you… The only issue is they don’t know much more then what JHM has provided.

DXC is just looking to try and unload the china turbos at the expence of jhm. Sad part is like its been said so many times. JHM had there turbo 2 years ago. Chances are better that DXC has gotten jHms old garbage that they didn’t want to sell. Thats why JHM had tehre 3 revisions. These guys are 2 years behind and are now saying look what we found… something that jhm did 2 years ago… we bet teher still doing the same thing… Its lame and its getting pethetic

There stories keep changeing. and thre attempts to pull people in are sad. Fact of the matter is ARD will get you the same 800$ mark up turbos that these clowns have. NONE of these guys is a shop none of these guys is going to have to deal with customers when these turbos blow… JHM like them or not is going to have to deal with people if there are failures or issues… Its not that hard to put two and two together here. JHM had there turbo 2 years ago… They made revisions and there selling a turbo that they know will last. There other guys are just selling the last turbo they found…

Amen brotha ^^^

I tend to stay out of stuff like this but… the motives and timing of the ProjectB5 and DXC are kinda clear. They started talking about this stuff months after JHM started the buz and frankly proved this to be a good product.

If im being honest. DXC and Project haven’t been honest here. Project or Im assuming (PB5) is the short version of the name. Pb5 and DXC have said they have all these cars running around with these turbos but just now. What? 2 months later have logs. No sorry. This is just more of there front. They have made hp claims. Yet no dyno. No proof of anything and where are all these people with the cars… You mean to tell me that there are 5 people that DXC and PB5 couldn’t get to go pimp them on line…ok sure…They were using a (apparently old version or first version) of the JHM turbo on the PB5 website. Come on guys. PB5 has been caught in how many lies now?

I think DXC thinks he knows where jhm gets there turbos but didnt he say he was going to have the invoice to prove it? ok where is that. But then didn’t PB5 say he was getting turbos from ARD? and JHM was cutting him off.

The fact still remains. JHM has had these turbos for well over a year. The add that JHM has was also basically linked to the one CV posted about a company looking for a made in china version of the JHM turbo. How do we know that the link CV posted wasn’t actually DXC?

http://audirevolution.net/addons/albums/images/979025367.jpg

Here is a request for almost a line by line copy of the Rs6r jhm turbos… How do we know this isn’t DXC or how do we know DXC isn’t getting these turbos.

I know all the drum bangers say we need the turbos compared we need them tore down… ok and who are you guys going to get to do that. DXC… sure there is a non bias party. They flat out said they get there turbos from china. JHM said something different. They said they didn’t. ok move on.

You guys need to do your homework with me7 tuning. These numbers are all based off maf scaling and he probably has an underscaled maf. You can make it whatever you want. He was showing that they hold over 18 Psi, which they do cause its much harder to fake the map readings. Probably a low-mid 3 sec fats which is comparable to healthy stage 3 stuff.

You guys just wasted a lot of key strokes focusing on that. No offense meant, just shouldnt be so fast to jump to conclusions.

#7

Hunter was not on pump gas, he was on a pump gas tune with q16 in the tank. Lets keep facts as facts. Nice meeting you last weekend Ian! You guys will have to come down in the spring for a track day!

I’ll bite, too. Here’s a MAF and an Acceleration log from my car:

J-Fonz tuned F21, 1st revision (boost was turned down due to bad boost gauge showing overboost, gauge reads 25, logs show 21.5):

Thanks for the info.

I mentioned the maf as just about every maf reading of those other cars I posted was also in the high 200s…(270-290).

I’ve never seen a stage three car b5 show an acceleration plot this low so it looks very odd.

Can you explain that further?

#10

Why exactly would you underscale your MAF when you log? Seems like you would lose any sense of comparison, or is this maybe his plan? Construe the info so no one can really compare his car to other setups???

#11

^from what I’ve read from the self tuning guys the MAF scaling is common and necessary to get a properly working tune

#12

You need to scale your MAF when you use the stock MAF sensor in a larger housing, which is necessary for everything but the stock K03s…

#13

Thanks for the info guys, I was honestly curious.

#14

can anyone talk about how this affects longitudinal acceleration readings?

#15

Acceleration = change in velocity/change in time (how the acceleration graph above was created). I don’t see how MAF scaling could affect this…

#16

Thank you! That’s mine for reference… Look at the image link :slight_smile: Car is still running that strong, I’m really impressed. I want to pull it apart next year and do a refreshed 2.7 all PC’d and clean seals everywhere, unsure of turbo choice yet.

Carry on.

#17

That’s what I was thinking, and that’s why I posted both the G reading and the MAF reading.

However I have zero experience in ME7 tuning so I can’t be sure.

#18

I’m in the middle of breaking in my clutch. I really hope to get real logs up first. Seems as if I always run into some snags, though!

When I post my RS6R logs…they will be real logs, lol.

#19

Who tuned your car?

#20

My maf readings from a conservative rs6 car-

Though I think my maf scaling is tweaked because I have a massive VAST intake pipe and maf housing.
