Dyno App on Android

[SupraPieces]

Just wondering if anyone has used any of the dyno apps on their android phone and how it compared when rating HP and torqe to actual dyno tests? I have it on my phone and without inputting all of the necessary information like weight, length, wheelbase and other characteristics it seemed to be pretty close to what I believe I have. 243hp 261tq. Seems reasonably close. Anyone else ever try any of these that have actually had their cars dyno'd, just out of curiosity?

what app did you use?

 

[SupraPieces]

The one I used was aDyno... again it asks you to input either a car from their database or your vehicles info and I didn't do that.

That would be badass if it worked or even came close to real numbers. I've only used the 0-60 and 1/4 time app

What did you use to secure the phone?

Lol... forgot to mention that.. the phone needs to be at a perfect angle (side-side and front-back)... when I bought the otter box case and holster for my Evo4g, they accidentally shipped me two of them... since I didn't need two and I use my phone as a gps (ever since my gps quit working) I took apart the holster and jb welded the cradle piece to my old gps suction cup mount... pretty trick if I do say so myself.. but any squeeze phone mount would work

oh and it does timed runs with 0-60, 60', 1/8, 1000' , 1/4 times.. HP and torque curves as well as g force and a bunch of other stuff

Anyone try it yet?

 

[mecevans]

Ill try it today. I recently dynoed so i know my real power.

I'd give it a try as well, but there is no way I can get traction until summer, and I doubt it's very accurate when faced with wheelspin.

This system would be based on accelerometers within the phone for playing their little games, wouldn't it? Would be neat if it worked, but I think consistency is going to be iffy, not to mention how this isn't the smartest thing to test on public roads haha...

Anybody else try it yet?

Bueller? Bueller?

I've used DinoDyno with some success in the past. The curves tend to come out pretty good for mapping the power band vs. rpm, but to get anywhere near accurate horsepower numbers it has to be almost drag strip smooth. My buddy's S13 Silvia with just intake and exhaust on it phone dyno'd @ 176hp with a guesstimate on the weight within 100lbs of actual (knew what it was without me and the driver and a few loose articles in the back). Did it with a 2nd gear pull. Power figure sounds about right for the car, but it's never been on a real dyno, so I can't compare for sure.

 

[SupraPieces]

Did he ever have a proper dyno run? I wold love to find out how near it was to the phone dyno...

No :icon_razz

I would imagine that would have been a tad low, SR20DET stock makes 202hp at the crank, add the intake and exhaust and the extra 1 - 2 psi of boost because of them and I would think it should be sitting around 180 - 185hp at the wheels. But who knows for sure, like I said, it never went on a real dyno and a couple years ago someone decided to hit him from behind and total the car.

Still interested to see if anyone who has dynoed their car has used the phone dyno and how close they come to real numbers...
