Most of you know Unitronic by now. They are fairly new but make awesome software for custom Turbo 1.8T's. Well they also have software for cars on Ko3's just like every other tuner. They released they're TT225 software and wow is all I have to say. On a MUSTANG Dyno, the dynoed a customers Audi TT225 w/ nothing but software and made 211 ALL WHEEL horsepower. If anyone wants to see the dyno plots let me know, pm me or whatever and I'll send u the link but just so you can no i found this on the "other" site. But everything is legit. I cant post pics at all so if anyone wants to post them up here pm me and ill show u the link or just find it on that site. Thats crazy imo, Ive beaten a 225 TT w/ software and other boltons w/ no problem, he has me off the start always though lol, I cant imagine what it would be like w/ that software. What do u TT guys think?
Well, APR's TT225 chip is about 255 HP, which is 210 whp. Keep in mind its 185 whp stock. Also, a Mustang dyno isn't the most reliable thing in the world. Between that, dynojet and dyno dynamics it's going to give you the least accurate numbers.
So am I impressed? Not really. Don't get me wrong, I've heard great things about unitronic, But that really doesn't sound like anything to write home about.
Mustang dyno is far more accurate than a Dynojet. Mustang dyno's also produce somewhat lower numbers than Dynojets as well. Do you have some reasoning as to why a Mustang dyno is innaccurate?
PS. Were you aware that APR Tuning uses Mustang dynos for all of their baseline and modded pulls? Most companies are using them because they are so accurate in producing real world numbers. AWE, APR, GIAC, BahnBrenner, etc.

yea you are for sure right audomatik mustang dynos also known as brake dynos made by companies like dyno dynamic dynos are the most accurate of all dynos and give more realistic figures. dynojets offer inflated numbers and are known as being less accurate.
Yes, it's true, Mustang offers the most accurate dyno. Brake vs Eddy current. Mustang being brake, Dynojet being eddy current.
The REAL reason many companies use them is because you can't increase the load with eddy current which makes it impossible to dyno tune load sites other than WOT because you can't hold an RPM / MAP location. Even my local emission stations use Mustang dynos as rolling roads for testing.
The unfortunate truth is that the abundance of Dynojets out there means that having "comparable" numbers with the rest of the world means putting your car on a Dynojet since it's the most common. Even though the same car on the same dyno on a different day will make more/less power it's as close as people can get in different locations.
This only furthers the nationwide 1.8t dyno number pissing contests on other forums... right up until someone shows up Mustang dyno numbers that are lower than everyone elses... then tries to claim he gets to add 20% because Mustangs show less power.

I guess I was wrong, I was under the impression that a mustang dyno wasn't a brake dyno. I did know the difference between the types, just confused who made what type.

Don't feel bad... we were all confused. Water brake dynos are usually engine dynos. My head isn't screwed on right, I got up earlier than usual today.
They're both eddy, but Mustangs are loadable, Dynojets aren't. Although DynoJet has stepped up to the plate and made one, it's the most expensive 2wd dyno they make, and they just came out with it a little while ago, so don't expect to see them at any shops since many buy their dynos used.

Well I thought that they were awesome gains for a K04 and AWD and that they were on a mustang dyno. I hear many people saying that the mustang Dyno #'s are off, but its usually because they're afraid of themselves getting lower #'s . Also everyone on the TT forum from u know where are impressed because they said 225TT chipped usually make around 190 awhp......soooo for Unitronic to put out 211, I think thats a great acheivement. I know that different cars react differently and all cars react differently to weather oif course but im just stating over all comparable dyno #'s. Brett, you have software dont you? Have you ever dynoed?
I think maybe the problem here is that we are talking about 2 different dynos like I said before. 211 whp on a brake dyno is far more on a dynojet, and that's what APR uses I think. 164 HP stock would be 27% drivetrain loss, whereas on a dynojet it would be more like 15-18%. That would give numbers more like what I would expect. So now that I understand that a mustang dyno is a brake dyno, I am on the same page. And on a mustang dyno it looks like most TT225 chips are around 180 whp, so I am impressed, yes.
So now that I understand that a mustang dyno is a brake dyno, I am on the same page.
No it isn't... go back and read my post. It's true that they read different numbers, but if you go back and read you'll see you weren't as wrong as you thought before. I'm telling you you're right. No matter how you slice it though... power gains are only relevant when measured on the same dyno (the same unit, not the same brand), with the same car, preferably on the same day.

Unfortunately, the test car was only equipped with a MBC for boost control. You will note how it effects the power curve...but decent #'s none-the-less on a moderately boosted GT2871R.

We all know that Aaron, atleast all of us who do know alot about tuning. The point was that Unitronic makes awesome software. Like Brett said, most AWD 225TT make around 190 awhp chipped, thats everywhere as an average. Apparently Steve Soeder ordered it for his car as well, hopefully he'll dyno it and give us results from Virginia, I hope you know who he is (680whp 1.8T MK4 GTI, sold it for a 225TT though...). I'll let you guys know if anyone else dynos, that way we can see Uni's increase on average... (Not trying o start a bash fest either, I know u know your shit very well .....).
I'm not arguing Unitronic, TT dyno numbers, or anything. I'm just laying out some truths about dynos, and stating things that everyone knows.
Chipping isn't something I care much about, I'm a standalone tuner, so I didn't get into, nor did I even bother to read that part of this thread. So no need to get uppity with me... since I wasn't disagreeing or belittling anyone here.

You said in your previous post:

Mustang being brake, Dynojet being eddy current.
But you just said in your last post that it's not a brake dyno...
According to their website they make both Eddy current and brake dynos. Maybe that's where the confusion is coming from.
