:mad: :mad: I'm so f*cking pissed of!!! :mad: Excuse my language.... :mad:
I just wasted $120 and 3 hours ot of my life at Kito Auto Sport in Seattle, WA.

It was a Mustang Dyno. I know they read a little lower but this is f*ucking ridiculous! :mad:

First of all, they ran the dyno as a 4WD. WTF? They told me that if you do burnouts with the car the ECU records that and it will void the warranty after 14 burnouts. WTF????!!!!?? BS!!!

I will post the graphs when they f*cking decide to email them to me.

335i Stock (NO Turbo Tuner):
233 HP
248 TQ

335i With Turbo Tuner:
253 HP @ 6106 rpm @ 109.2 mph
287 TQ @ 3276 rpm @ 59.8 mph

And they had the nerve to tell me that: "maybe the powers loss is more like 23% not 15% like BMW claims...that would explain the stock numbers that you got!!!" Give me a break !!!! :mad: :mad:

WTF????

I am not pissed with the Turbo Tuner (I like the product!!)....I'm more pissed with the dyno stock results and wasted time and money...

Just venting...

:mad: :mad: :mad: :mad: :mad: :mad: :mad: :mad: :mad:

they probably coudlnt get it to dyno because of the ABS fault code that gets thrown when the front wheels dont spin... this causes the transmission to go into fault mode, and it will not hold a gear... so they fixed that by running all 4 wheels, which will majorly screw up the results.

What you are supposed to do is once the car is all set up on the dyno, turn it fully off, then back on, then DO NOTHING until you hold down the DTC button for 5 seconds, and completely disable all traction systems, then select your gears in M mode and start your run...

The whole voided warranty thing probably came from the time that BMW would void warranties if you overused the launch feature in SMG on the m3. That shop was full of idiots... go somewhere else

$120? What a scam! As a general rule of thumb if you're not tuning your car, only use a dynojet. It's the only way to compare against Internet numbers.

I don't get Mustang Dynos.
I've been told the new software for them makes them read closer to what a Dynojet does. This one apparently is not a newer Mustang Dyno.
But still, 233 HP to the wheels???
That would be like 23% drivetrain loss, IF the car actually made only 300 hp from the crank.
We all know it's closer to 320 HP from the crank in a 335i.

Even if the 335i had EXACTLY 300 HP at the crank, a decent and 1/2 accurate dyno should still show 245-255 rwhp.

Should of just found a Dynojet in your area.

Mustang MD250 vs. Dynojet 248C
Dynojet 248C is actually an accelerometer whereby it uses a 3000-3200 pound drum that is used to create an inertia load on the vehicle being tested. The vehicle's horsepower (HP) and torque try to overcome the weight/inertia of the drum to accelerate it. As a result the software and electronics try to measure the horsepower and torque that the vehicle is developing to overcome the drum's weight and inertia. The resulting horsepower and torque will be higher than a true loading dyno because once the drum starts rolling not as much power is needed to keep it going. Example -- When pushing a car on a flat road, once the car starts moving not as much power (effort) is needed to keep it going. The software does not ask for vehicle weight or anything like horsepower needed to maintain 50 MPH (a number that is actually put out by E.P.A. and N.H.T.S.A.).

The Mustang MD250 dyno is a true loading dyno, because it uses an inertia weight as well as an eddy current motor that is attached to the rollers. This eddy current motor creates a drag on the shaft by way of electricity that causes a magnetic field to try and overcome the torque going through the roller shafts. This current is controlled by software that is always trying to simulate load as if the car is driving in real world conditions. The real benefit from the loading dyno is the ability to maintain a load that allows a tuner to properly go through a fuel map or ignition map and tune the chip for optimum horsepower and torque. It has the ability to also simulate the IM240 emissions test as required in some states. It can check 1/4 mile times as well as times for 0-60 MPH and 0-100 MPH. It can also be used for road testing and simulation for drivability problems. As a result of the loading capability, the dyno numbers from a mustang dyno will come out lower than the inertia (dynojet) dyno. Further information can be seen at www.mustangdyne.com

O SNAP!!! Is this the KAS that made the exhaust way back in the day when e90post first got started? The name sounds soo familiar.

In regards to burnouts and m3 launch control... it's all a myth, mostly.

In the U.S. a manufacturer cannot void a warranty due to use of a function available on the vehicle, i.e. smg launch control. However, that is why U.S. spec m3's have a much lower rpm launch than the euro spec cars.

Why do you care about the number? The only thing that matters is the gain, and you picked up 20 whp and 40 wtq....looks to me like you had a pretty good day.

I don't get why people get all worked up about a low number when they have a baseline number to compare it to. You know how much power 335s put down stock, so do some math if an ego inflating number is that important to you.

HAHA....That is exactly what i was thinking. Pretty sure they were in Seattle, the guy was talking about working on Sonics player's cars.

The fact that his baseline number is so far off of other peoples' numbers calls into question all the dyno pulls done on that dyno by that operator on that day. It's too easy to say something was done wrong so you can not trust any of the numbers.

20rwhp is pretty weak, the lowest gain I've seen on here was around 26rwhp and most are picking up 30-40.

Hmmm maybe it's Turbo Tuner's crappy map. Terry - go hack it and show us what they're doing.

If all the cars were putting down 20rwhp it would be one thing, but everyone else is doing closer to 30rwhp+, so it tells me this is an outlier. When I had the TT I connected a boost gauge and found it was putting out around 11psi, ~3psi over stock.

Dyno may need to be recalibrated.

[WilyB]

You max power / torque rpm appear out of whack too.

Terry - I was joking.

[bmwzimmer]

So you got a 10% hp increase and a 15% increase in tq. That's not bad for what you paid.

+100000
took the words right out of my mouth. Most 335i's on 91 octane baseline around 275-280 tqe and about 270-280 hp. So 290-300 whp and 315-320 tqe. Done. I accept cash check or cc for my incredible math skills.

It has nothing to do with the actual number, but more to do with an appropriate number!
True, dynoing a car is more about the "gains" than the actual number.
But if the actual number is not an "appropriate" number, it calls into question the validity of the "gain" number as well. (ie: his 20 hp and 40 tq gain, might register 30 hp and 50 tq gain on a dyno that reads more "appropriate" numbers for the power the car is really putting out.

Clearly the stock 335i puts more HP to the wheels than 233.

Yeah, his percent HP gain was the lowest of anyone with a TT so far. I would question those results as well. For comaprison I gained 18% more HP and torque with the TT compared to stock.
