Dyno your car using only your phone - Perfexpert

Here's something I loved and you're going to as well. Dyno your car using nothing but your smartphone. You don't even need GPS, and it actually works. I'll admit I was extremely skeptical when I first heard about it from a guy on a forum. He posted dyno charts that he got using absolutely nothing but a $9 smartphone app. So I decided to spend $9 and download the app which is called Perfexpert by the way. I am in no way sponsored, endorsed etc. by the makers of the app. I paid for it with my own money and I was not paid to make this video. Had the app sucked I would have told you so. The surprise is that the app actually worked. I tested it out on my 100% stock Suzuki sx4 to be sure the data it got was correct. And it was really close to factory specs, showing only that the peak torque and horsepower are developed at slightly higher rpm than stated by the factory, which is definitely not implausible. I couldn't use my MR2 for this because I don't know the power it makes, but now that I know the app works I can't wait to dyno my mr2 with this. Conclusions: I definitely recommend this, it actually works. I included a step by step tutorial on how to set up the app so it gets accurate data. It needs a lot of data and parameters on your car otherwise its completely useless. Check out my blog for more: http://www.driving4answers.com/ #d4a #phonedyno #perfexpert
