I just got the new iPhone app Dynolicious today after reading about it in the W211 forum. I have the 1st gen iPhone and works great: Here's my post from that thread. If you have an iPhone and a W210 you need this!!!

I got the app this morning. It is pretty fun if you can find nice open roads. Don't know how accurate it is, so I posted results for debate. The 210 E55 is "supposed to do" 5 flat 0-60, but I kept getting times from 5.9-6.2 which sounds reasonable since I've never drag raced and can't really launch that well. The real time graph is AWESOME!!!

3 runs. 91 degrees outside. 3 to 5 minutes between each run, engine running the whole time and the car had been driven for 30 minutes prior to reaching secret location. No more than 10 minutes to complete all 3 runs:

Run 1: Traction Control On (12:59PM)
60" - 2.54 @ 28.3mph
0-60 - 5.98
1/4 - 14.31 @ 100.2mph

Run 2: Traction Control On (1:05PM)
60" - 2.63 @ 28.2mph
0-60 - 6.11
1/4 - 14.49 @ 100.8mph

Run 3: Traction Control Off (1:08PM)
60" - 2.54 @ 28.1
0-60 - 6.2
1/4 - 14.56 @ 100.7

I forgot to reset the ecu, so I got no wheelspin from the 3rd run even with TC off. I am going to repeat the test, after adding Lucas Fuel Cleaner, reseting the ECU, doing an oil change, and replacing the air filters this weekend.

The W210 has a brilliant mounting point! All you do is take the ashtray out and slide the iPhone in. Pull up on the bottom of the iPhone and it will wedge itself in exactly in line with the front of the car and it will not slide or move around in any way. I did notice the cupholder can angle the phone away from the true front reducing accuracy, but the ashtray removed mounting point is completely flush. As the phone lays nearly flat you also can cleary see and manipulate the touch screen to start the run. Plus if the fuzz is on to you, you can close the ash try lid/cover with no problem!!!!

the proper way to mount is 100% horizontal with some sort of mount to keep it 100% stationary with no slipping around. Remember it has to be 100% flat or the results will not be 100% accurate. Even a tilt of 5% can cause the results to not be that accurate. Just a suggestion.

Actually according the mounting intructions on the iPhone app itself, it says:

"The iPhone can be oriented in any angle between flat and vertical, however it must be aligned with the direction of travel."

As long as it is first calibrated correctly (I used a 90 degree ruler for intial set up) and mounted properly before starting the run I think it will work fine. The app goes through a calibrtation before the run can be stared. I think this measures the current mounted angles vs. the initial calibration to adjust the numbers.

I will try the test again mounted in ashtray position, then repeat the test with the iPhone secure in the top portion of the center console since thats parallel with the ground.

doesn't it do dynos as well? can't it give you a rough calculation of HP & tq?

armaniE55

That does sound pretty sweet. the iphone is just plan badas@ ... Damn you Verizon....only way to get my grubby little hands on that phone is to change network...

I just ran the beast again. Only one run. Car been driven for only 15 minutes to testing location. 49 Degrees outside. 1/8 tank of gas. TC off (Lots of spin). All else same as previous 3 runs.

Results:
Run 1: Traction Control Off (11:36PM)
60" - 2.50 @ 30.2
0-60 - 5.33
1/4 - 13.67 @ 109.3

I think the significant drop in temp accounted for the better run. Notice 60" is about same, but 0-60 and trap speeds were 10% better (approx 6 sec v. 5.3 and approx 110mph trap vs. 100)

Peak RWHP calculated at 272rwhp, by iPhone on this run. Previous 3 runs calculated at between 230rwhp and 235rwhp. I know the hp figures aren't terribly accurate, but can heat soak account for such a drastic loss?

I think it is a nice toy to play with... however it will not replace real dyno or track runs... good luck and be safe

AMS Performance

272 is actually pretty damn accurate. Rememer it reads as a Dyno Dynamics dyno would (actual real wheel torque) not a dynojet so those numbers are actually pretty damn accurate. how did you calibrate it? in order to get 100% accurate results you have to make sure all the inputs are accurate and precise.

Also getting a true mount will still help improve the results furthermore.

I'm not sure how accurate the ETs are, but it gave me a peak HP rating of 443...which is close to the 440 a Dynojet gave me.

SaMaS

I have fersh dyno done not long ago on Dyno Dynamics maybe i should try tonight and see how accurate this thing is...

AMS Performance

Give it a shot Samas, let us know how it turns out. I just got an Ipod Touch so I really want to know your impressions. Hell, I figure for $13 a program that is more accurate than Gtech is well worth the money.

It is a fun thing to play with. I certainly wouldn't use it to try and validate a claim, i.e I run 10s all day according to my iPhone. That would be ridiculous. However, the more of us that have it and contribute we could average the numbers and see what the average times for w210s are with and without mods.

Also see my initial post about calibrating and mounting instructions. Removing the ashtray and wedging the phone in works like a charm! I think the key to accurate times is proper calibration and mounting.

SleepersRock

I used a 90 degree ruler to make sure the calibrations were done correctly. Also the mounting point I mentioned FIRMLY secures the phone exactly in the direction of travel and allows the user to operate the app with ease.

thebenzbar

That is so cool!
Just shows and validates (to an extent) that a n/a E55 can still dish out plenty of ***** even when compared to today's market of aspirated euros...
It may not be the quickest or fastest beast but those times are still

e36mmm

i want that app for my blackberry so i can try out my 0-60 times

xlr8tin

Hmmm, just saw this thread...thanks e36 for bringing it back up...Hopefully this app is still around for a good price

You can get different ones for Android phones too. All sorts of them out there these days.

I saw this thread today and immediately bought this Dynolicious for my new Ipod Touch. Set it up and tried it when I was out and about. No ECU or shift reset. I put the A/C unit on economy.
Just one run and I was holding it flat against the dash in vertical position. Here is the results of my one run. I will do it a few more times to get a baseline...then again after Thurday's header install!I ordered a window suction holder for it today. MUCH FUN for $12!
