Look what I found:

Surprising the accelerometer is that accurate.

 

Nice find indeed~!!!!

 

Wow! I wonder just how accurate it really is? I'm debating right now if I should. DL it or not. Some of the reviews on iTunes are saying it's still really buggy. Maybe Jon can be the geuine pig? Heh heh

 

Yeah I'm debating it also. I don't trust the App Store reviews anymore because 80% of the whole store's reviews are from a bunch of idiots who don't follow directions.

 

I've been using it a bunch today, since I contributed to that article, and I haven't had any issues with it crashing. Unusually slow to edit and add cars, but it's never crashed. Overall a great little tool so far.

 

damn, I'm tempted to install this given there's a rally-x this Sunday

 

I Love You!

 

Alright, bumping this up!

Has anyone actually used this yet? I'm having trouble with mine. I tried tonight, but I'm not sure when I have to let off. I did a run tonight, but let of at around 80 mph.

My 0-60 was 7.16 secs, my 1/4 was 15.99, and my estimated HP was 173 WPH. Is this thing that inaccurate, did I use it wrong, or is my car just that slow!

 

what kind of car was it? Those numbers look like a stock wrx auto. In fact, those numbers look exactly like it.

My numbers from my car was close to what tested numbers for my mb was

 

My car is an 06 Manual Stage 2. I'm pretty sure I'm supposed to be making more numbers.

How did you test yours, did you go flat out?

 

Did you calibrate?

Also, you need to make sure the phone is positioned in a certain way. I haven't really got a chance to use mine though.

 

WHP is lower than crank hp. Always.

 

That is correct and I am sure touge knows this.

However, if I am understanding correctly from his post is that he is getting numbers that are near what an auto wrx bone stock will give, not what a stage2 06 5spd wrx would give. I believe the correct range on 06 WRX Stage 2 will be in the area of 230-245 WHP.

People who have the app knows that you have to calibrate it when the iphone in 6 different positions: up down sides bottom top. I also leave the unit running on my dash while doing runs. Also, make sure it's set right on the drivetrain loss and total weight(including yourself and gas).

 

I think the problem is I'm letting of the throttle too early. My max speed is reading as 96.2 mph on the phone. I went again later last night and got my numbers a little better. But I still let off before 100.

I wish we still had at least our drag strip here. I'm really hesitant to test this ***** out on the road, especially because I live in town.

Oh yeah, I calibrated twice just to make sure.

 

i wonder if suspension would play a factor.
