bobt Posted February 10, 2009 Share Posted February 10, 2009 On recommendation from a friend I bought and downloaded the 'Dynolicious' app. Turns your iPhone into a G-Tech like thing Its great, no connection to the author, just a satisfied customer.

Area Representative Nick Chan Posted February 10, 2009 Area Representative Share Posted February 10, 2009 Rob, I have seen a couple of threads about this app on Seloc. I think they say something about entering the weight of your car to calculate BHP. How much is the app? Do you just set it going and accelerate? How accurate do you reckon it is?

bobt Posted February 11, 2009 Author Share Posted February 11, 2009 Hi, best bet is to look up the app on the AppStore. Lots of text and reviews telling you all about it. Rob Link to comment Share on other sites More sharing options...
h_____ Posted February 11, 2009 Share Posted February 11, 2009 There was a (mini) review in the back of 911 and porsche world, they thought it was quite good / accurate. *think* it was about $30 Link to comment Share on other sites More sharing options...
Support Team Shaun_E Posted February 11, 2009 Support Team Share Posted February 11, 2009 It's £7.49. For that money I might give it a go. Yellow SL #32 - member of Drowned Rat Racing Link to comment Share on other sites More sharing options...
Mavic82 Posted February 11, 2009 Share Posted February 11, 2009 It may give you a figure and it may sound reasonable but it will not be right. The kit to do just a basic acceleration test properly is about £8k and it does not use accelerometers. The closest peice of kit to this that produced roughly the right bhp figures was called Dynomet and worked off a measured distance, wheel rotation, declared gear ratio's, weight and needed a coastdown period to estimate losses. Evan that only gave an approximation and needed 10+ repeats to take an average. Acceleraometers should only be used for one thing measuring the acceleration of an object. If you do this in a car the resultant acceleration time history in 'g' must then be interpreted to provide an understandable result peak figures, RMS and other various averages. It's bad enough on the F1 coverage when they say the car is cornering at 4.5g B****x! Even with wings the laws of physics can't do that. Just an inappropriate measurement from an accelerometer measuring an instantanious peak reading. So in summary, fun bit of kit to play around with to give an indication of whether one vehicle is likely to be better than another (in gross terms) but that's it.
