Track runs and....Dynolicious works!

[amd is the best]

Hey guys, I might as well make this a two in one post here. I made it to the track tonight and ended up with a best of a 11.8 @ 118 (1.75 60ft) and a best trap of 11.9 @ 121 (2.0 60ft, lots of tire spin). On a side note, I downloaded the Dynolicious app for my iPhone and I can't believe how good this thing works! Here i will post my timeslip results vs. the dynolucious results:

Track:
2.0 - 60 ft
5.279 - 330 ft
7.865 - 1/8th
96.92 - 1/8th mph
10.105 - 1000ft
11.973 - 1/4
121.41 - 1/4 mph

wow the iphone wasnt off much at all

[amd is the best]

I forgot to mention, this is not the same run. Just two runs in the same night.

[AMC]

was this on race or pump gas?

[2001S4NY]

did you spray it in this run?

[amd is the best]

Spray (50 shot) and race gas on both the runs.

[S4 in_lowplaces]

I bet with a new tune you could be running low 11's. Have you tested anything above a 50 shot yet?

[bassed]

I love dynolicious. What are you cradling the iPhone in? I can't mount in my ice<link due to the angle.

75 shot jets are in the mail. I have to order a wideband as well, so I can see where my afr's are. My fuel jet me be a little over conservative which is only hurting my apr softwares over conservative tune, lol.

It fits perfect in the cup holder up against the radio. I don't know how to explain it, may I can get a pic if you want.

hey man whatsup!

OP. nice! that iphone is really close like AMC said. I would of expected it to be a few MPH.... how did you calibrate it ? My buddy wants to download it and SOMEHOW get it stable on a worked up CBR900... is that even possible? to get it working with a bike

It works on anything that moves, you just have to make sure its mounted good and pointed foward.

[AudiA4_20T]

impressive but I would expect more... You can run those times with an OTS K04 file

It's apr software which is the most conservative ots out there. 118 is about the best trap for and apr car so 3 mph with no traction in the launch is not to bad for a little untuned 50 shot.

[RolledMySTi]

Nice runs, but I think with a new tune you could be low 11's. Thanks for posting the info on dynolicious. Now I have to get an iPhone.

[AMC]

agreed. low 11's is def in this cars future. oh and mike i got my D3!

[soccerplayer01]

hey, nice meeting you last night. cars real quick and def good lookin. i had the other silver s4, Mike, there that ran really slow. lol. i also think i have video of you also in different views.

[NogaroWonda00]

very nice, i have an iphone too but i hacked mine so im still on 1.1.4 but im just waiting for the 2.0 to get hacked!! did you use your little charger dock or what i didnt quite get what you were explaining..


also i was wondering why your doing a 50 shot vs a water/meth kit? how much better are you expecting to run with a better tune..

[HeveyS4]

It's apr software which is the most conservative ots out there. 118 is about the best trap for and apr car so 3 mph with no traction in the launch is not to bad for a little untuned 50 shot.

where do you get that 118apr is the best trap. I ran a 11.77 @ 120.63 on apr stage 3 with race gas and dumps. I have hit a 121.xx mph. so i would expect with a 50 shot you should be in the 123 or so. unless your running it through a full exhaust.

I just got my meth kit installed and im looking to run a high 11 with pump now.

nice run tho.

Please do! I tried it on my iPhone and I'm getting ridiculous numbers and times.

[BlackS4TT(Josh)]

Nice! What weight and drivetrain loss did you put in the application?

[bassed]

Please do! I tried it on my iPhone and I'm getting ridiculous numbers and times.

Grab the update and calibrate it. I use it in my Jetta Wagon and it's accurate like his, but in the A4 I can't mount it any where, it falls out of my cupholder above the radio.

[sixfiveoh]

I'm putting in 13% DTL and 3000lbs for my FWD, sound about right?

[hoosierchemist]

I'm putting in 13% DTL and 3000lbs for my FWD, sound about right?

why not just use 0% DTL? That way you will get wheel horsepower out of the program.

Also, you can go by a junkyard and weigh your car to get an "actual" weight.

[RenegadeEngr]

X3 for Dynolicious. What a great program. Can you post a pic of your mounting? I'm real interested to see!!!

[JDM EJ1 95]

wow you guys are trapping pretty high for OTS pump stg 3s.. at 118

best i can trap is like 115

[BlackS4TT(Josh)]

I hope you're kidding.... there is still drivetrain loss when wheel horsepower is measured.

[Nebone]

Get a sticky cell phone pad and leave it on the dash board.

[hoosierchemist]

I hope you're kidding.... there is still drivetrain loss when wheel horsepower is measured.

Obviously, but that is why wheel horsepower and crank horsepower are different. When you enter 0% DTL into Dynolicious, it does not apply a correction factor and the horsepower it reports is equal to the horsepower you actually feel....you know, the wheel horsepower.

will NOT work, i have one and everytime i launch the phone flys somehwere

no, it wouldnt... whp is the power you put down to the wheels AFTER drivetrain loss... 0% correction would be chp or crank hp, not whp.... 22% would be more like whp

[hoosierchemist]

I hate to sound like an ass, but here goes.

Do you even know how the program works???? The accelerometers in the iPhone / iPod touch detect the acceleration of the car AS IT PUTS ITS POWER TO THE PAVEMENT. (I might add, that this is the definition of wheel horsepower). Therefore, to estimate the crank horsepower, the program takes your measured horsepower (which MUST be wheel horsepower) and uses the estimated drivetrain loss (let's say ~22%, why not) to converts it to crank horsepower.

example: I was playing around with Dynolicious one night, made a horrible launch, end up measuring 14.7 @ 104 1/4 mile with 242 HP. If I had input a 22% DTL, the same data would have resulted in:

1 - 22% DTL = 78%
78% (power after drivetrain loss) = 242 HP
242 / .78 = 310.25 CRANK horsepower

[Evilevo]

Correct, but im pretty sure the App applies the correction to get Crank Horsepower, not wheel

[Das General]

He was on race with a 50 shot.

[JDM EJ1 95]

yea and trapping 122.

im talking about the others in the thread trapping 118 with their ots 93 tunes

[saucys4]

Since no one has commented on this here it goes. It looks like dynolicious can be pretty accurate but I am still pretty skeptical about its precision. It just doesn't seem like its that consistent. I know you did more than 1 run run at the track. How did the other runs compare with dynolicious?

[hoosierchemist]

Correct, but im pretty sure the App applies the correction to get Crank Horsepower, not wheel

In this case, the two of us are saying the exact same thing.

The only frame of reference the program can possibly has is what the wheels put to the ground.

Since we agree that dynolicious applies a correction (based on the % DTL) to get crank HP, then we must conclude that it actually measures wheel HP. Therefore, entering a 0% DTL will result in no correction and display your wheel horsepower.

Agreed?

Picture of the mounting arrangement please!

I bought an iPhone shortly after I saw this app was available. I wanted the phone before but this put me over the top! Plus there's a free A4 driving game!

I used 25% for drivetrain loss... should I use less like 22%? I also need to get my car weighed and figure out how much gas weighs! lol

Mounting pics (or my best attempt):







And just for the hell of it, I ran it on my APR stock mode this morning and came up with this:

[Das General]

I can't even get a cup to stay in my "cup holder" and you somehow manage to get a phone to stay...

It's 12.99 I just got laid off and it's still not to expensive to play with IMO. Buck up and buy it for some fun.
