I got mine today (amazon prime, free two day shipping). Works great, slight moment of panic when it required a passcode to pair with my phone. For my device the code was "1234" other users on the interbuts report "6789" worked for them. In either case you have to pair the adapter immediately upon plugging it into the car. Like in under 30 seconds. I found it worked best for me if you have the phone ready to find new devices, and then plug the device into the car when its running.
As far as the torque app goes, its pretty cool. I got to get to the scales and get a good weight for the car, with me, and with fuel. I estimated the best I could and came up with 3960 lbs and it was decently close to what I expected. Since it's a calculation of vehicle weight and speed and a bunch of other information it provides an estimated HP number to the wheels.
The best I got was 211, which is in the ball park of what I expected. I guess drive train loss would be somewhere between 20-25%
So stock 06, according to wiki makes 280hp. So a 25% drivetrain loss would equal 210 at the wheels and a 20% loss would be 224. This factored with an my best attempt at an estimated weight seems a somewhat reasonable range. I have a K&N intake, but I don't really believe it adds any tangible horsepower. Maybe someone who has dyno'd an LS, can comment on an actual drivetrain loss. In the meantime, I'll have to hit the scales.
I only gave one attempt but was able to snag a 6.8 0-60, not bad.
Also I can confirm this
http://www.amazon.com/gp/product/B009F4JHHO/ref=oh_details_o00_s00_i00?ie=UTF8&psc=1 adapter works well, the speeds of information transfer are acceptable, and is small enough that you don't know it's there while your driving, despite the fact that the LS OBDII port is right above your right shin. The adapter comes with a mini disc containing some various software. I WOULD HIGHLY advise just tossing that cd in the trash. I scanned it and it contained two trojan horses. I searched on the internet and apparently some software on the cd is not legally obtained.
Anyway, for a total of 24 bucks ($19 for the adapter, $5 for the app) this is a pretty cool toy, and it reads codes to boot.
Now, time to go put it on the work vehicle. :steering
